Still crunching for Seti. We had a few warm days during the week so the Nvidia crunchers were off during the day. Credit is currently around 23.8 million with a daily output (RAC) around 71,000. It looks like its going to take a while to get to the 25 million target.

The oldest Raspberry Pi has locked up a few times today for no apparent reason. Given all the SD cards were replaced a couple of weeks ago I don't think its the SD card this time.

Yesterday Nvidia announced the GTX980 and GTX970 cards based upon the Maxwell architecture. Looking at the specs of the GTX970 they look like a good replacement for my GTX670's. Depending on pricing I may just get a pair. They have more CUDA cores and use less power.

Nvidia are dropping CUDA support on the older cards that are Pre-Fermi (ie Pre-GTX460). If you've got one and you use CUDA then don't upgrade to the latest drivers.

Nvidia also seem to be moving to 64 bit for CUDA with the latest Apple Mac drivers only being available in 64 bit.
