Hello !

I have a problem running WU's on UBUNTU 14.04 / Linux 3.11.0-19-generic

It stops after 1 second => error

GPU = NVIDIA GeForce GTX 660 Ti (2047MB) + 1 CPU core dedicated to the GPU

Do you have any idea how I could solve this issue ?

Hereafter the message I received :

Stderr output

<core_client_version>7.2.42</core_client_version>

Thank You

Kind Regards,

Try replacing your "boinc" executable with the projects modified 7.3.15 version, available from HERE
This reports your driver version to the server so it can send the correct task to your computer.

Thank You, I will try.

The boinc executable provided by the project may report the driver version, but has problems, the most important of which is not keeping task checkpoints correctly. This means you may be crunching a 10-hour WU for say 8 hours, then suspend boinc or the GPU and when you resume, BAM the WU starts all over!! I know because I tried it and lost 3/4 of a NOELIA_BI! Not good...

Better stick to the latest official boinc version.

What NVIDIA driver do you have currently installed? I've been having problems myself, after adding a 750Ti next to my 650Ti, and I've found drivers 331.49 and 334.21 to work well for me, the latter performing better as well.
