I needed to remove it because it loaded a huge number of GPU tasks of very short duration which erred one after another, but tied up the GPU preventing three other GPU projects from running any tasks. I am still running SETI for CPU only on four other machines. http://sciencespringe.wordpress.com http://facebook.com/sciencesprings ID: 1312286 ·

This is a new machine so the drivers were the "latest and greatest". But I had 301.42 on GTX 670's before. http://sciencespringe.wordpress.com http://facebook.com/sciencesprings ID: 1312323 ·

Either project runs OK alone, but when you are switching between them weird things seem to happen? Someone else may remember more info about this? Ian ID: 1312419 ·

In fact, the other projects were fine with the new driver. I am just glad to be able to do for SET@home whatever I can, to respect its position as the "mother" of all BOINC. http://sciencespringe.wordpress.com http://facebook.com/sciencesprings ID: 1312584 ·

Ian Not all Cuda projects have thread safe Cuda apps, 270.xx drivers and later react badly to terminating processes mid kernel execution, and with recent Boinc versions, one project's Cuda app can be pre-empted so another can run, which can cause driver restarts and downclocking: Recent Driver Cuda-safe Project List Claggy ID: 1312628 ·
