      you may as well abandon them all. Since they are past the deadline you won\'t get credit. Any new work will have a longer deadline and I hope as more accurate estimate to completion.

        you may as well abandon them all. Since they are past the deadline you won\'t get credit. […]

        That’s not necessarily true, in most projects—and the way things are going around here these days, deadlines are almost irrelevant. In order for you not to receive credit for a late but otherwise successfully completed task, at least three others have to be submitted before yours.

        Browse any batch of current WUs and you’ll see that very few have more than one successful result: errors and “No reply” all over the place. Moreover, almost all our hosts either still have more work than they can handle or, if participating in other projects, aren’t asking for work because SDG has run up a CPU-time “debt”; this means the replacement tasks for late or erroneous results are only trickling out. The upshot is that although you may have to wait a long time for it, chances remain good that a successfully completed task will earn credit.

        AFAICT the main factor militating against this likelihood is the maximum number of errors, which is ten here. (I’m not sure whether or not “No reply” counts as an error.) However, I expect the failure rate to decline as stragglers come in and replacements start getting crunched, because our ‘once bitten’ BOINC clients will be ‘twice shy’ when they next ask for work, most likely getting only one task at a time. Unfortunately those who had all their tasks aborted, without completing any at all, won’t have benefited from the experience … OTOH Ádám has been known to manually grant credit for successful tasks that get ‘orphaned’ by circumstances beyond users’ control …

        @Lotus: When you say “no progress”, do you mean that the “Progress” column in the Tasks tab says 0.00%, while many hours show in the “CPU time” column? Or are you just concerned that you haven’t completed any tasks yet? If the former, that’s definitely a problem; if relaunching BOINC (maybe rebooting) doesn’t produce some improvement within a few hours, you should abort that task.

        I see that you crunch for a lot of projects, so you should probably abort any tasks that haven’t started yet as well—unless you don’t mind your computer working on nothing but SDG for the next few weeks. But if you have tasks that are showing incremental progress, they could well be worth finishing: from a quick look through your WUs it appears that nobody else has returned a successful result for any of them! It could easily be a another month or two before they’re ready for validation.

        In any case, suspending tasks (or the project itself) isn’t going to help in the long run: either give them a serious go or abort them. Remember you have the option of setting the project to “No new tasks” while you deal with whatever work you decide to keep, if you want to await news before taking on more.

          We\'ll I didn\'t get any credit. There appears to be a lot of issues with this site--gross underestimation of durations, faulty programs that take forever to run and yield no credit, too short of deadlines, etc....

          Good luck to those of you patient enough to help resolve them.

          Fairwell.

            I have a few workunits that I did not get any credit for due to too many results.

            I hope they sort out the current issues soon.
