My cruncher has produced ~70 terminated WUs in quick succession with the following STDERR output;

Here's the BOINC start-up messages showing it's starting state;

Any idea on how to resolve this and what is error 212?

Thanks,

Interesting update on my failed GPUGRID WUs. I stopped WUs for GPUGRID and loaded Einstein@Home. So far, the machine is crunching E@H GPU WUs with no errors while the GPUGRID WUs were failing immediately. Anyone else having issues?

Same problem here. Probably it is related to Nvidia 331.38 driver. They were going to drop support for it. We should update to newest drivers but the drivers in the repos have problems with CUDA and Boinc.

CPU tasks are crunching but when I restart Boinc all the progress is lost...

I'm not experienced with Linux, but you should check the "Important news for Linux crunchers" thread.
You are right about that your drivers need to be updated.

I had and stopped crunching for Gpugrid. But after some days checked and it got CUDA42 jobs and crunched them succesfully. Now tasks are said to be cuda42 but ends with an error, probably they are cuda60 internally and need the driver update.

I thought the new drivers weren't required until 2015? My cruncher has been completing CUDA 42 WUs successfully until today. I've tried unsuccessfully for several hours to upgrade drivers to higher then 331 with no luck and was hoping to run CUDA 42 WUs through the end of 2014. For the time being I've stopped accepting work for this project until someone can find a solution to the CUDA 42 WUs terminating with errors. I'm fairly certain that it's a project issue as the cruncher is completing E@H GPU WUs successfully.
Thanks,

I thought the new drivers weren't required until 2015? My cruncher has been completing CUDA 42 WUs successfully until today.

That's fairly strange, since your BOINC still reports it was using the same 8.03 CUDA 4.2 app as it was doing before. "Removing support for this" would mean to disable this app completely.

It could be something in the new WUs not being compatible with the old app. This would then probably be a mistake.

I don't check in often so I upgraded my box earlier this month.

It completes the jobs in about the same 18 hrs as before but now it only uses 3% of a core instead of 98% of a core.

Consider giving the 343.22 driver a try. I had to search the nvidia site for a while to find it but I eventually found a 343 that was not listed as beta. The machine is running ubuntu 12.04.01 LTS server if that makes any difference. I like running the server without x-windows to save a few cycles.
