I get the feeling the GPUGrid is only for an exclusive club of members. I want to donate time for GPUGrid, but I think the deadline times you get is a borderline joke.

I just restarted my GPU work load again, and the first work unit i got was with a estimated time to complete: 32 hours. Fair enough. Then I look at the deadline. 5 days. Lets just do some math here.

I'm home and have turned on my computer on normal workdays 16-22. That gives me 6 hours of potential computation time. I normally use my computer, so it's more like 1-2 hours of computation time that will be available. That gives BOINC an effective computation time of 10 hours pr work week.

I'm short 22 hours.

Weekend are sometimes different. Maybe I can give 7-8 hours on a weekend. So that's 16 hours + 6 for 3 weekdays. 24 hours in total. I'm still 8 hours short.

And all those calculations is with a IF i'm home attribute.

When I look at some of the other GPU project there is out there, then it just gets worse. WCG offer GPU computing for Help Conquer Cancer. Their estimated completion time is 2 minutes. Fair enough, GPUGrid has more stuff to work out. But WCG offers a deadline of 7 days. 2 more days for a unit the is vastly smaller than GPUGrid.

I want to help GPUGrid out. I really do. The project is something personal that I want to support, but the deadlines just denies me.

Could we please increase those deadlines to something that can give us mortals a fighting chance to help you out?

There won't be longer deadlines, this research project needs fast wu returns.
In your case, you should not crunch the long workunits. These are intended for enthusiasts, who leave their PC turned on 24/7.
You can select the type of workunits you want to run on your hosts in your profile.
Click on your user name on the top right.
Look for the Preferences for this project
Click on GPUGrid settings.
Uncheck the checkboxes of ACEMD beta and ACEMD for long runs (8-12 hours on fastest GPU).
Save your settings.
In the BOINC manager select the GPUGrid project, and click on "Refresh".
I suggest you to abort your current long workunit if it won't finish on time, because it will be resent to another host if yours doesn't report it until the deadline, and if the other host reports it before yours, you won't receive any credit for it.

I did not knew they had that option. Thank you. I'll test to see if i'm able to complete those instead.

you should easily be able to complete the short tasks by the deadline.

The long tasks really are for people who have dedicated rigs or are able to leave their computers on overnight.
Note also that the current long tasks are reallllly long. so a 460 will struggle to complete them.

Welcome back to GPUGrid by the way! :)

Topic very, very old but I think it should be refreshed. I don't know how did it looked like 5 year ago but now Short Run task are phenomenoms. Some people haven't got ultrafast computers and don't stay them turned on 24/7 but they want to help. Mayby deadline for Long Run task would be a bit longer? I think 7 days might be okey. In fact it may accelerate work because more people would join.

The deadlines are so short because each work unit runs off of the previous result, so if some people forget that they are accepting work and never complete it, it will be a very inefficient process with a longer deadline. There is always CPU work for those without a fast gpu/don't leave their computer on all the time.

A don't claim that deadline should be unlimited :D But 5-day-long deadline for Long and Short Run tasks isn't fair. 7-day long deadline for Long Run tasks would give chance more people to complete their work.

It was more balanced between the short and the long workunits before. The purpose of the short queue is to make the owners of slower GPUs to be able to contribute. It's too bad, that the project does not have that much work to feed both queues with sufficient number of workunits.
It wouldn't accelerate the work if more people joined with slower cards:
1. This project needs fast turnaround times, as the workunits pick up on the point where the previous one had finished. So extending the deadline would mean that the whole chain of workunits would take significantly longer. Other projects work the opposite way: their workunits are independent from each other, so extending the deadline does not increase the completion time of the whole batch.
2. Years ago, the deadline was 5 days, but after 2 days the work was sent to another host too (so the 1st one may work in vain). So practically the deadline was 2 days, while the BOINC manager (and the user) thought it was 5 days. This caused much frustration, and it had been corrected long ago (by eliminating the reissue after 2 days). But as you can see from this earlier practice this project would be better off by a 2 day deadline.

If your logic isn't to have unlimited deadlines, it's certainly to bend the rules to fit your systems' specs. This messes with every one else's setup, and does not benefit the project.

If your setup is not able to contribute, move on. You will get another chance. In the mean time QC has a full queue and doesn't even require a GPU.

QC doesn't need GPU but needs much of disk space. And I don't want to band rules, I think only that they aren't perfect. Is it something bad?
