Got same error code on my Linux box for several tasks:

http://gpugrid.net/results.php?hostid=447186

Most recent task, I suspended the task before it began. I rolled my computer's date back a month (February to January), then resumed the task to let it begin.

It didn't stop with an error immediately, that's a good sign.

I waited a minute, then returned my computer's date to real time. It's still running, hope it finishes okay.

More than half the current research projects on the server status page are now showing amber for the error rate. That's the sort of signal that might attract the admins attention.

I've had no response to my PM, but if there's no sign of change by tomorrow morning I might try again.

It was going so well, but suspending and resuming with the date set to February caused the error again. The app seems to check the date at the beginning, and upon resuming as well. Ten hours of work wiped out, d'oh.

Trying again, starting with a January date and then trying to never suspend. Maybe it'll work this time.

BOINC never keeps a task scheduled for a GPU in memory (there's no equivalent of paging or a swap file for graphics memory), so every 'resume' is actually a complete application relaunch. Try to avoid letting it swap out.

Success! So fiddling with the date is a possible workaround for Linux users.

Edit: P.S. Suspend other tasks before rolling the date back. It's okay if they stay in memory, but if they're running, the rollback will lock them up. There are probably other ways to do it, but to be safe: I suspended everything, then rolled back date, then started GPUGRID task (manager won't show it running, but it is running), then corrected the date (manager now shows GPUGRID running), then resumed other tasks, and made sure the GPUGRID task never suspended.

Got a response to my trouble ticket at acellera.com about the app error from Gianni.

the error message is misleading, there is no license to request. We are already fixing the application in gpugrid.

So I hope that we see a new Linux application from him shortly that doesn't error out.

[Edit] There is also a new News item mentioning the issue.

[Edit2] Question from me:

Thanks for the reply Gianni. Any estimate when that will be made available?

Gianni's reply

not yet, but it will be posted on gpugrid forum. We have a problem that the person that builds it is out until the end of the week. We have to see if the others can do it without him.

Looks like the same issue with the Short Acemd tasks. Thought it might use a different application, guess not. Same error in Linux as before.

Will have to wait for the developer to fix the application.

Should we turn off GPUs in the meantime to avoid failed WU or it doesn't matter ?

Perhaps better to help out another project temporarily until this one is ready for you again?

Just completed a WU for the new version 9.19, seems to be working fine.

I've already done and validated two new tasks with the 919 application. Original problem is resolved.
