The WU 2283038 looks good. 70% completed with 10hrs26mins (4hrs14mins to go). Please do not abort this WU. I will post the WU\'s progress again.


An update on this WU 2283038. 75% completed with 11hrs26mins (3hrs42mins to go). Looking good.


Another update on this WU 2283038. 90% completed with 13hrs24mins (1hr31mins to go). Nearly finish.


Further update on this WU 2283038. 95% completed with 15hrs20mins (49mins to go). Almost ...


This story ended sadly. When the WU is completed and uploaded, a \"Too many total results\" error is generated. I counted the total replicates to be 11. So in any cases, this error message will be generated and no credits will be granted. A lesson learned but the system should keep the replicates to 10 and not sending out excessive WUs for crunching.

May I also contribute an example, the most recent WU completed on my Linux machine:

Tried to download some new WUs and it seems that I am lucky today. All WUs completed in short time. They are

WU 18226 0f740a11-ddf9-... completed in 0.5 hr
WU 16751 247cb2c2-8265-... completed in a little less than 1 hr
WU 16731 21b342bd-9be3-... completed in 6.7 hrs

All units created on 1 Oct and they were crunched on my PC with Pentium 4 CPU 2.80GHz.

I am happy to report that 4 more WUs have been completed since my last post. They are

WU 18716 21b342bd-9be3-... completed in 3.7 hrs
WU 18648 247cb2c2-8265-... completed in a little less than 2 hrs
WU 18481 247cb2c2-8265-... completed in 2.4 hrs
WU 18224 21b342bd-9be3-... completed in 25 hrs

I would think that the new WUs are acceptable. Of course, it would be much better if the WUs could give crunchers a realistic idea of how much time they may take and show progress. However, if the present algorithm and the BOINC software are unable to give us what we want, we should accept as is to keep the project running. We have to work to progress.

This is the final update of WU 2478 as I have, reluctantly aborted it after the deadline passed. The final CPU time was 232 hours and progress was 20%. Regarding the two other computers crunching this unit, one has aborted and the other has no reply. I have set all computers attached to the project to \"no new work\". I shall continue to monitor the situation and when the computation time problem is solved, I will surely return to the project.

I would update my WU figures since my last message and provides, hopefully, some views for SZTAKI participants for further discuss. It seems that the board is very quiet, because perhaps, everybody is too tired crunching the LLLLOOOONNNNGGGG WUs.

My WU is now at 120 hours and, well, still at 10% and the other two crunchers have also not finished yet. Too sad.

BOINC, evolved, from the original SETI@home is to allow scientific or mathematical projects to utilize idle CPU cycles of computers around the globe. Credits are given to participants as a commendation to their efforts. As a matter of fact, the credits have no money value. Nowadays, many crunchers, like most of us, turn on our computers 24/7 in order to take part in many BOINC projects. We pay the electricity bill, bear the tears and wears caused by the non-stop running of hardware. We, without noticing, become too much concern about getting credits, remembering that we had asked Adam over and over again: \"where is our credit?\", until well we were satisfied.

Now regarding the long WUs, the gut of the issue is nevertheless the same: \"where is our credit?\". We gives our CPU cycles to the project but cannot have any credits. I understand that Adam is correct in a way that he does not know that exact run time. But I, as from the point of view of many crunchers, would ask whether the credit system could be, say, modified or relaxed. The suggestion may include, if technically feasible,

- extend the report deadline of further WUs and Adam to announce the existing WUs could be granted credits even completed after the deadline;
- grant credits to WUs even there is client error.
- for \"maximum CPU time\" error, I have a machine running climatepredition.net and the WU has report deadline over 1 year and is now running over 2000 CPU hours without error. Could SZTAKI be modified as such?
- give credits even the 3 quorums cannot be satisfied.

For my part, I shall let my Notebook to run the WU for at least until the report deadline. I am now leaving my machine to run overnight to maximize the run time. For all of you serious crunchers, please give Adam some time. Like the \"credits problem\" before, he would eventually sort out the problem.
