The test and regular WUs are completing fine now.

Hopefully. Short queue is dry.

So I can check the preference to accept long jobs on my GTX 680?

Doubt it. Haven't seen word from researchers yet.

The CUDA 4.2 application is now available for long workunits.

I've downloaded one long 4.2 for Linux and one for Windows. Looking forward to seeing how both perform against the previous app for different tasks. Both should start within two hours.

Zoltan, I see that on one of your rigs Nathan's tasks run about 50% faster.

I1R47-NATHAN_RPS1120528-12-166-RND6733_0 3521240 25 Jun 2012 | 10:43:53 UTC 25 Jun 2012 | 22:51:32 UTC Completed and validated 17,171.72 607.02 60,900.00 Long runs (8-12 hours on fastest card) v6.16 (cuda42)

BTW.
Not having any useful info in the <stderr_txt> messages with the new app isn't going to help!
