Had a crash on the cuda program x86 last night. Switched back to the V6 packages. One of the main problems with V8 and BOINC 6.45 is it requests less work by the day. It has a buffer of < 4 day with a setting of 10. (this was before there was no work) All task run way below 1 hour but the rest time counter always stay above 1 hour and mostly on 1:20 1:30. Seen a task complete at 20 Minutes and the rest time went ... up instead of down as it normally does.

Switching back to V6 is meaningless. They deprecated already. V8 CUDA app has all improvements from V6 + some more.
What crash you had to decide such downgrade ?

Why? because I run some other projects as well and e.g. Wold Community Grid is greedy and downloads a lot of work and goes into High p mode. That stops the Cuda task altogether and worse SETI does not download any work, so the buffer gets very low. When you have a new AP ready I switch to that version. The completion time is now about 15 Minutes and on the V8 it goes to 1:30 and more even as the work is done much faster.

Try V7, but not V6.

Done, but the cuda exe is the same MB_6.08a_mod_VLAR_fix_CUDA.exe. And the AP is no longer working anyway.
