Einstein does CUDA

We have finally begun to automatically deliver CUDA work & applications (plan class "ABP1cuda23") to machines that satisfy the following requirements:

- enabled NVIDIA GPU work in Einstein@home preferences
- NVidia GPU with at least 450MB of free memory
- Display Driver version 190.38 (&up), i.e. CUDA 2.3 capability
- BOINC Core Client version 6.10 (&up)

CUDA Beta App testers should drain their work cache and switch back to the normal project work.

Oh well that should keep the GPU warm while SETI is borked and out of WU

Thanks for the heads up, it was beginning to get cold in here

Looking at the thread it doesn't seem like a very efficient use of your GPU

Its improving... http://einstein.phys.uwm.edu/forum_thread.php?id=7683&nowrap=true#101108

Our tests indicate that the upcoming ABP2 GPU tasks typically take ~0.6 hours per WU. This is still "just" a factor of 2-3 faster than the ABP2 CPU version, but after the ABP2 release we are going to concentrate on improving the GPU code.

Do yu need to substitute the 2.3 dll's?

(like you do with SETI)

I've got version 2.3 dlls in the einstein folder but I don't remember putting them there. The files also have slightly different date attributes from the ones I put in the SETI folder so I think its likely that it gets the new versions by itself.

Thanks for the info

Its got another big bit better

ABP2 will perform the same search on the same data as ABP1 currently does. But due to code optimizations and a smaller template bank it does this much faster; also ABP2 results don't validate against ABP1 ones, so we set up a new 'application'. We expect the ABP2 WUs to take ~1/5 of the time of ABP1 WUs.
