I have run afoul of the excessive work unit download this version suffers from. Einstein has downloaded 30 or so workunits (cuda) and none of them are starting. I know cuda works because seti and collatz are using the GPU. I have suspended this project. What version should I revert back to and what are the proper steps to get rid of the excessive Einstein work units and to recover proper functioning of this project?

Environment is vista 64b with nvidia 9600m GT GPU.

How much memory do you have on that GPU? Einstein's ABP2s run in approximately 400MB of video RAM. And then it's only doing the FFT calculations on the GPU, all other calculations are done on the CPU (so you need one free for that).

You can return to the recommended 6.10.18, available from http://boinc.berkeley.edu/download.php (but do check if it downloads the 64bit version, if you have a 64bit BOINC at this time).

That's not necessary. Just deselect using the GPU in the Einstein@Home preferences.

However, if you can't free up enough GPU memory to get the already downloaded tasks started, you'll have to abort them.

You won't even need to downgrade BOINC if that's the only problem you have with that version.

That is interesting, I looked all over the Einstein web site and could not find any cuda requirements. I do have 512mg of video memory so looks like it should run.
Thanks for your help.

Nope, there are many threads on the Einstein forum about hosts where a 512MiB GPU doesn't have enough available memory to run Einstein CUDA tasks.

You could enable some logging options (cc_config.xml) to see exactly how much memory is needed/available, but the name of the options has changed lately, so I don't know which one you'd have to use (depends on your BOINC version).

Thanks to all of you. I aborted all the cuda workunits yesterday but they are still showing in the client and are taking up 750meg of disk space. How do I physically get rid of them?

Click update.
