That is an excellent run down.
Thank you.
As you point out,new development versions are arriving with great frequency.
BOINC 6.3.21 has been treating me well on 64 and 32 linux and on 32 XP
I see that 6.3.23 has started to roll out already for Win and Mac
The only hurdle I see on the Linux side for the CUDA effort is the terribly poor performance of the NVidia 17x.x desktop drivers causing XOrg to go into a spin and swallow 100% of 1 CPU. This is a multi-distro problem (and not a topic for this thread).
In the mean time, I must suspend the CUDA client and put up with the NVidia-lag when I want do do something useful.
But when I plan on doing some real work for a prolonged period, I have to unload the NVidia drivers altogether, which means no CUDA work can get done at all.
Having a CUDA unit running makes it impractical to use the desktop, but this is not a CUDA issue. The problem derives from the NVidia driver itself.
Getting CUDA to work with PS3Grid in Linux and still allowing the owner of the Linux boxen to interact with the desktop may be a good incentive for NVidia to finally fix this driver issue.
I do hope so.
