After looking the

After looking the documentation movie "Cathedrals of Culture" (2:45h) I started 8 tasks on one machine - 4 on each GTX670.
No problems until now: Progress about 5%, GPU Usage 97%.
I'll will report if anything changed.

Win7 x64 host with two GTX

Win7 x64 host with two GTX 750Ti cards. First betas of the cuda55 app have reduced runtime by about a half hour - from around 2 hours 25 minutes per task (running 1x) with cuda32 (v1.52) to 1 hour 55 minutes with cuda55 (v1.56). Better than a 21% improvement.

I've posted improvement

I've posted improvement results (22%+) for a first host on the CUDA32 to CUDA55 performance thread in Cruncher's corner and suggest that others with performance observations not bearing on actual problems with the new application consider posting there rather than here.

I run 3 BRP tasks at a time, since I have a mix of CUDA 32 and CUDA 55 tasks in my 1.5 day cache my question is will running 32 and 55 CUDAs play nicely together?

Hm, can't say, if this was a 32 bit or 64 bit programm run, not visible in the logs. ATM the 32 bit executables are being used. Hope that this will be a clean run.

Windows (32Bit) version 1.57

Windows (32Bit) version 1.57 will be published soon. This just upgrades the CUDA 5.5 libraries to the latest available version 5.5.22 (from 5.5.20 used in version 1.56).

It's a shame the version 5.5 CUDA FFT library is so big - 67 MB for each version, and BOINC doesn't discard the previous one. The next release up, CUDA 6.0, is back down to 27 MB (all for 32-bit files).

I just did 2 ending in an error in less than 2 seconds. not a big loss for me, but a disappointment because I want to use more of my GTX660's capabilities.

After the download was finished they still said the were d/ling on the task page and then they all were deleted and this stderr
