    Hi, Adam!

    I\'m back from two extended trips, and I see that not much has been done with the WU time problem with the exception that there has been another update to the Windows Application to correct errors.

    Any possibility that there are similar errors in the Mac OS X version? I don\'t believe that I have had a single completion without an error on my Mac G4. I keep hoping for an update that has some possibility of completing successfully in time.

    Until then, I will keep a watching brief on the message boards.

    George

      My old G4s, running “Panther” (OS 10.3.9), have been doing OK. My G4/400 has completed eight WUs successfully over the last couple of months, although it hasn’t yet received any credit. The G4/733 has only completed three, as it’s been working on a very long task (due Oct. 31!) for the past several weeks; it’s showing 60% done after some 300 hours of CPU time. I’ve suspended it for the weekend because I have deadlines coming up in other projects, but I’m reluctant to abort it after all that time; we’ll see what happens next week.

      Anyway, I guess the verdict won’t be in until the validator has had a chance to do its thing, but ‘from this end’ v2.00 has been running fine, albeit often slowly, on both my G4 Macs.

        Thanks for that info. I am running OS X 10.4.8, and the processor is a dual 1GHz G4, so there may be some difference in how it handles threads.

        By the way, if you are running BOINC, you don\'t need to worry over deadlines. BOINC will handle multiple deadlines better than you can schedule them.

          My dual-core G5 running the same OS has had no errors either (touch wood). Are you running any other BOINC projects? There is a known issue concerning insufficient shared memory on multiple-CPU Macs running several projects; the solution involves a minor reconfiguration of the system. What kind of error messages are you seeing?

          By the way, if you are running BOINC, you don\'t need to worry over deadlines. BOINC will handle multiple deadlines better than you can schedule them.

          In this case, I think not: once BOINC is in EDF mode, the task with the earliest deadline gets top priority. That G4’s SzDG WU is already long overdue, and would continue to get 100% of the hosts’s resources, even though at this point another day or two is unlikely to make any difference, especially considering the increasing likelihood that it will get the maximum-CPU-time-exceeded error—but Einstein@home work (of which I had a few tasks due today) usually gets sent out and turned around quickly enough that a missed deadline will almost certainly result in redundant work, even if it ends up getting credit. AFAICT the BOINC scheduler isn’t capable of making such ‘judgement calls’. That said, situations requiring intervention are rarely encountered.

            I am runing seti@home, einstein@home and world community grid. There is 1GB SDRAM in the system, and any time I have monitored the memory usage, there is at least 100MB free. Active memory rarely exceeds 500MB. I get errors like:

            Sun 19 Nov 23:17:44 2006||Can\'t rename state file: Error -1
            Sun 19 Nov 23:17:44 2006||Couldn\'t write state file: system rename

            but that seems to be a synchronisation problem.

            Tell me about the shared memory issue: I haven\'t heard of it.

              but that seems to be a synchronisation problem.


              Or perhaps access permissions? Have you verified your volume with Disk Utility recently? Rebooted to make sure no stalled or ‘ghost’ process is claiming rights to the file?

              Tell me about the shared memory issue: I haven\'t heard of it.

              I’m no expert, but AIUI the BOINC core client communicates with the science apps using shared memory; a block is assigned to each ‘live’ task, each corresponding to a folder in the “slots” directory. With two or more CPUs and several projects one can have quite a few Running and Preempted tasks at any given time, each of which needs a chunk of shared memory reserved for it. The problem is that Apple’s default allocation is quite stingy—4MiB—and is the same for all systems regardless of the number of CPUs or the amount of installed RAM.

              Before I get over my head, let me just refer you to an article on the issue from Pirates@home, including instructions for increasing the allocation over what’s provided in the default configuration. The fix seems to have worked fine on my G5, which started throwing “Can\'t create shared memory: system shmget” errors shortly after I attached it to its fifth and sixth projects in September; I haven’t had any of those errors since—and IIRC I’ve only rebooted the system once in the meantime.

                  Yep. At some point, BOINC changes all permissions — perhaps to lock out other processes — and the state file can\'t be renamed. I\'ve tried again and again to set the permisssions on the state file so that it can be renamed, but BOINC persists in resetting them. Since the error doesn\'t happen very often, it has to be some synchronisation issue with BOINC itself. I regularly check disk permissions with Disk Utility, as well as checking disc health with fsck, although with the current system, I only get problems with a crash, which hasn\'t happened for ages (I run the system 24/7).

                  Tell me about the shared memory issue: I haven\'t heard of it.

                  Thanks for that. I haven\'t had any trouble with running just four projects, but if I do, I\'ll change the size of the shared area.

                    That might be a good idea, but make it ‘Mac OS X’: OS9 is dead.

                    An even better one would be to ensure that all posts are in English or another Indo-European Language, or translated. :-) Magyar is not an Indo-European language, and because it is highly irregular and agglutinative, is extremely difficult to learn. Thus, although I can get along in about 6 other languages, most of them Indo-European, Magyar isn\'t one of them. Most other non-Hungarians have the same problem: it is not a common second language.

                      The Magyar is the one of the Official languages of the European Union. So try to learn it somehow. ;)

                        Like many other eastern European languages (Indo-European or not) it’s also much less widely supported by online translation services than are those from larger countries, or from nations that once had worldwide empires. However, since the project is based in Hungary, it doesn’t seem reasonable to disparage Magyar here—and now that the character-encoding bug has been fixed in the forum software, the text is no longer the scrambled eyesore it used to be …

                                Szerinted nekünk nem nehezebb megtanulni azt a teleszájú, tök mást leíró, mint kiejtő hablaty-féleséget, amit angolnak mondanak?!

                                According to this site Attis said:

                                \"Sandal everyone? l , but unlocks.
                                According to us not heftier learn that the teleszájú , gourde mást expository , than pronounce? seamaid - assortment , that eel legend?!
                                /Sandal everyone? l , but unlocks.\"

                                Can\'t help thinking that if this is the best that dedicated translation software can do then what hope have the rest of us got of learning Hungarian? On the other hand, if there is a chance of being offered an assortment of seamaids, then it might be worth putting in some effort.

                                    Tried it with other two on-line translators - there\'s always a sandal offered along with seamaid-assortment (this better be good ;). I\'m a little bit worry about this eel legend - never know what kind of sea monster you can meet when trying to make acquintance with whole assortment of seamaids ;)

                                      An even better one would be to ensure that all posts are in English or another Indo-European Language, or translated. :-) Magyar is not an Indo-European language, and because it is highly irregular and agglutinative, is extremely difficult to learn. […]

                                      Like many other eastern European languages (Indo-European or not) it’s also much less widely supported by online translation services than are those from larger countries, or from nations that once had worldwide empires. However, since the project is based in Hungary, it doesn’t seem reasonable to disparage Magyar here—and now that the character-encoding bug has been fixed in the forum software, the text is no longer the scrambled eyesore it used to be …


                                      There was no intention to disparage Magyar, and certainly no intention of being Anglo-centric. The point that I was trying to make is that not only is Magyar a minority language (in the sense of population: certainly not in the sense of artistic and scientific contribution to European and world culture), but it is reputedly a difficult language to learn because of its high portion of irregular structures, and it is unrelated to other European languages (except distantly related to Finnish and Lettish, other minority languages), and thus even those of us who are amateur linguists shy away from tackling it. Moreover, because of its lack of relation to other European languages, it is even impossible to guess the meaning of a phrase or sentence.

                                      In a world where the current Lingua Franca is English (for whatever political or colonial reason: once it was Latin, and before that Greek, and so on), it then makes sense to conduct correspondence in that language. For instance, I note that Attalla is a major contributer to several of the threads in these fora, and that he has also replied to my comments. I have no idea what he said in reply, and several people who attempted to use online translators have come up with a mish-mash that indicates his reply is an idiom based on Magyar culture. If that is the case, it seems quite rude to me for \"insiders\" to comment on my communication when I cannot even divine their intention.

                                      Indeed, that is illustrative of the reason I raised the point initially. While it is true that it is a Hungarian University that has begun this project, by requesting computer time internationally, it behooves the locals to invite us into their circle of intercourse: otherwise, why should we not feel that we are being used, rather than participants? Two of the three message boards are entirely in Magyar, and this one occasionally has what appears to be important correspendence in Magyar — correspondence in which the rest of us are unable to participate.

                                      While my appeal was tongue-in-cheek (wretched English ideom for \"not completely serious\") and marked with a smiley, it arose because of my frustration at not being able to read some of the correspondence that appeared to be important. I guess we need a human translator.

                                        Some time ago I set my Athlon Duo running (Windows XP SP2) and my Mac PowerPC Dual 1GHz (running OS X 10.4.8) machines to no new tasks, because neither machine was successful in completing tasks in time, or they suffered computational errors. Three days ago, I re-activated STAKI Desktop Grid on both machines because of the success others were reporting and because Adam reported that most of the long tasks had been finally flushed out of the system.

                                        Since then, the Athlon Duo has completed five tasks successfully, with three already having been given credit.

                                        The Mac machine, gwgg4pmac.local, on the other hand has completed two tasks, work id 31021 and work id 31037, claiming success for both, but receiving not credit for one: the other is still pending, but with a similar error log, so I think it too will fail.

                                        Here is the error log for work id 31021:

                                            Nope. Not a single task has completed without error for either of my two G5 machines. 0 of 5 for my Quad, 0 of 4 for my iMac.

                                              Update: The problem I was having was with 5.8.3 and 5.8.4. By downgrading to 5.8.2, the -161 errors have stopped. I have since successfully returned two results. Hopefully, that was the only problem. Fingers crossed!

                                                i\'ve got dual g5, and it\'s 20% with 63 hours of cpu time...
                                                is it ok?
                                                this is my first task with sztaki...

                                                is there any mac finished a task?


                                                Yep. Out of about a dozen WUs (that I didn\'t kill: I have killed maybe 20-30 on this machine since I started running last October), I got credit for 2 or 3. I have stopped running SZTAKI on my Macs because they run so slow and yield mostly empty or bad results.

                                                Every now and then, I start one up to test the water, but I intend to wait until the queue of pending has emptied. There are now 3 in a queue of 5 that have not expired due to timeout, and I expect 2 of them to fail: for example, one WU has 5 pending results without a quorum, 3 client errors, 2 timeouts with no reply, and 1 running that expires on 9 February.

                                                I eagerly await some improvements in the checkpoint algorithm, and some optimisation for Macs.

                                                  Yep.

I have stopped running SZTAKI on my Macs because they run so slow and yield mostly empty or bad results.

                                                  To some extent my experience with my G5 has been similar; it’s had a better success rate in terms of getting some credit—but it usually gets much less than it claims. It’s now 192 hours into a ‘five-liner’, showing 60% done, which has just put BOINC into EDF mode because it’s due on the 31st. At least the second core can keep me ‘in business’ WRT my other projects.

                                                  As I mentioned near the top of this thread a couple of months ago, my G4s have been going very slowly: I have one task at 720 hours & counting at the moment; another that took ~680 h has been pending for quite a while now at “Checked, but no consensus”. At this rate, my sample of completed results is too small to make any meaningful conclusions from, but I haven’t noticed any errors recently.

                                                  I’m still making up my mind about keeping my Macs in; while they could be earning more credit or contributing more usefully elsewhere, I don’t want to withdraw altogether—particularly since this project is one of comparatively few that has made the effort to support the platform at all.

                                                    Hello Odysseus I agree with you.
                                                    I\'ve stopped this project on my Macs, though I would like to stay.
                                                    The reasons are like you wrote:
                                                    less credits running to slow and furthermore to many errors.
                                                    I hope it will be possible to make at least a application for intel-macs in the future which is running as good like that one for linux or win.

                                                      That G4/400 finally submitted its result this weekend, having crunched for just over 744 hours—for which it received 129 credits, less than a tenth of what it claimed.

                                                        And some other host with an invalid result received more credit than you with your valid one - bummer. Congrats on sticking with it though.

                                                            Well, as the saying goes, “you pays your money and you takes your chances.” I’m mainly glad it turned out valid—and I think it sets a record among times posted here, for successful results at least, in which I can take a perverse kind of satisfaction. My G5 just got a maximum-time-exceeded error after 223 hours, on the fourth line of a five-liner. Considering the benchmarks, that would likely be something like 1000 h worth on the G4 …

                                                                  is it ok?

                                                                  is there any mac finished a task?


                                                                  Yep. Out of about a dozen WUs (that I didn\'t kill: I have killed maybe 20-30 on this machine since I started running last October), I got credit for 2 or 3. I have stopped running SZTAKI on my Macs because they run so slow and yield mostly empty or bad results.

                                                                  Every now and then, I start one up to test the water, but I intend to wait until the queue of pending has emptied. There are now 3 in a queue of 5 that have not expired due to timeout, and I expect 2 of them to fail: for example, one WU has 5 pending results without a quorum, 3 client errors, 2 timeouts with no reply, and 1 running that expires on 9 February.


                                                                  Things have hardly changed. There are still 3 outstanding WUs.

                                                                  I eagerly await some improvements in the checkpoint algorithm, and some optimisation for Macs.

                                                                  George

                                                                  On reading this thread, there still seems to be no action on legitimate complaints about the Mac version. In another thread, I offered to have a go at a newer port but got no answer: so is anyone working on a Mac update? If not, why not? Recent posts on this thread seem to indicate that more and more Mac users are deserting the project, which is a real shame.

The Applications page indicates that the version is current. Perhaps something got rearranged in the recent website update, so the download server can’t find the file?

And here\'s been the project serving up to us WUs that can run for 200+ hours. Followed by a roll of the dice whether credit is granted or not.

                                                                                            But I was impressed by the 2.06 app crunching your WU in 19 minutes on a G4 and 7 on a C2D. I figured maybe 12 minutes on my G5 2.0GHz.

                                                                                            So I downloaded my first WU in six months. I received a 5-liner. It took 3 hours to do the first line. As I write this it is at six hours and, to judge by the checkpoint file, only appears to be halfway through the second line. So I\'m guessing the total crunch time will be in the region of 20 to 30 hours. Not exactly the 12 minutes I expected.

                                                                                            And I switch my Mac off at night so I hope restarting in the morning doesn\'t invalidate the WU. It isn\'t a problem that has affected me before so maybe Macs handle that issue better than other platforms. I\'ll let you know how it goes.

                                                                                                But I was impressed by the 2.06 app crunching your WU in 19 minutes on a G4 and 7 on a C2D. I figured maybe 12 minutes on my G5 2.0GHz.

                                                                                                So I downloaded my first WU in six months. I received a 5-liner. It took 3 hours to do the first line. As I write this it is at six hours and, to judge by the checkpoint file, only appears to be halfway through the second line. So I\'m guessing the total crunch time will be in the region of 20 to 30 hours. Not exactly the 12 minutes I expected.

                                                                                                And I switch my Mac off at night so I hope restarting in the morning doesn\'t invalidate the WU. It isn\'t a problem that has affected me before so maybe Macs handle that issue better than other platforms. I\'ll let you know how it goes.


                                                                                                Hey,

                                                                                                I was using a _test_wu_ 1-liner, stripped down, not a real world wu,
                                                                                                prepared and used for testing (and from the 10 dimension space, so that it
                                                                                                finishes faster). This has nothing to do with the runtime of a real wu.
                                                                                                I posted the results to demonstrate the \"picture\" what to expect, just
                                                                                                for comparison. And the picture is that it took ~19min instead of the
                                                                                                1h+ (which is rather long for testing).

                                                                                                The runtime has nothing to do with the runtime of wu-s we are distributing,
                                                                                                they take rather longer to finish (we cannot say how long it will take :( ),
                                                                                                but the speedup is there too.

                                                                                                You can switch of your mac, since the app checkpoints, so it will continue
                                                                                                working the next time you switch it on. The wu-s have deadlines set so, that
                                                                                                should not be any problems with not finishing on time.

                                                                                                  How many time do you need to run a wu ?


                                                                                                  ( Standalone mode means that you run the app from command line, and not
                                                                                                  through the boinc manager).

                                                                                                  In standalone mode, the application does not use the boinc manager, so it
                                                                                                  is always running, uses all cpu time available (and reports back nothing).
                                                                                                  So when you run it normally, it depends on the settings of the boinc manager
                                                                                                  (when is the app allowed to run, how much cpu time it is allowed to use).
                                                                                                  We could think of this as a theoretical minimum, but since it was only
                                                                                                  a test wu the run time does not say anything. Instead use it for
                                                                                                  comparison (~19min vs 1h+), so you can see there will be \'some\' speedup
                                                                                                  for the real world wu-s.

                                                                                                      i was talking with adam about this, and he wants to investigate this problem.
                                                                                                      anyways if you have any other problems with the mac/linux app, pls let me know.

                                                                                                        I was using a _test_wu_ 1-liner, stripped down, not a real world wu,


                                                                                                        Thank you, Attila, I understand. There was just something about your comment about being bored after one hour that amused me.

                                                                                                        However, I seem to have hit a checkpointing problem.

                                                                                                        I have been regularly opening the minute-by-minute checkpoint file in a text editor and have seen that in this 5-line WU, each line has a range of 24 or 25 \'steps\' to calculate. Thus it is not difficult to judge approximately how far the WU has crunched at any given time. When I switched off the first night, It was just past halfway on the second line, about 33% total. The Boinc Manager [5.8.17] was correctly showing 20%. Next morning the Boinc Manager immediately jumped to 40% but the application continued as it should from the 33% position. When the 2nd line completed, the progress remained as 40%. (I wondered if it would incorrectly jump to 60%.) This all continued fine for three nights.

                                                                                                        Last night when I switched off it was at step 22 in the final line and showing 80% progress in the Boinc Manager. This morning, as expected, the Boinc Manager jumped to 100% but the application did not resume processing from the (approx 96%) checkpointed position. The result was sent off immediately with the final 2 or 3 steps remaining uncalculated.

                                                                                                        WU
                                                                                                        Result

                                                                                                        Of course, even the above assumes that each \'step\' was calculated correctly on restart, either by continuing from the exact correct position within the step or by recalculating that step from the start. No way for me to know that.

                                                                                                        Just for reference, processing times were:
