Demoting Vista x64 to 32-bit is rather drastic. This is a S@H-issue, as several weeks of GPUGrid-chrunching did not produce any problems at all. It was very stable - no babysitting necessary. What could shed proper light on the cause is to run a debug-version of the cuda-app... Morten Morten Ross ID: 857681 ·

What do you mean under "debugging version" ? Do you want pdb-file to run under debugger? ID: 857727 ·

If the cuda-executable is compiled with debugging flag set on, it could log debug-information to file for further analysis. Or is there a way to activate verbose/debug logging (eg /d or /v)?

Morten AFAIK no useful debug info provied, but you can try -verbose switch... And try to reproduce hang in standalone run. ID: 858016 ·

Interesting, I recived some reports like yours already. But still can't reproduce this behavior on my hardware. Could you post OS you used, link on affected host on SETI site, link on affected results. In short - I need more info about your setup to try give some more or less constructive answer. ID: 859004 ·
