AK V8 + CUDA MB team work mod
Jason G:
AKv8 stuck? Uh Oh...(never heard of that before..) I didn't do it :P Exit stage left ...
Archangel999:
i don't know it some boinc problem because before 5 hours it work 3 work unit now when i come back it is working all the 5 again from time to time stop working 1 or 2 unit but they as you see on the pic are in the memory and the boinc says that they are running i don't know maybe because my xp is x64 ?? >:(
Jason G:
Ahh, may not apply completely in your situation, but this is basically how it works for me. I reckon it is the imperfect Boinc scheduling mechanism still. Thinking logically through my situation (And extending it to quad core scenario, I have only dual core so I'm using my imagination):
- 5 tasks going ( 4 x CPU & 1 x Cuda, Total ~4.04 CPU + 1 Cuda), was possible because cuda started first!
- Cuda task finishes.
- Boinc says I have 4 CPUs & 4 apps allocated (no more room for 0.04 CPU required for CUDa)
- Boinc waits until 1 CPU task finishes (Gets down to 3) then allocates a new cuda task, has available CPU so allocates another AK task afterwards. (five running again)
For myself, it worked best without using any ncpus mod, and sticking with Boinc 6.5.0.
Yeah I found it frustrating enough that I went back to running the v7VLARkill mod & AstroPulse on the CPUs, but with AP off on main, no longer a suitable option.
I hope there might be some useful clues amongst that mess, that might apply to your situation.
Jason.

aham but doesn't explain that when there are only 2 working and 3 working not 5 will wait to see the answer for the Raimster :) Thank you

Still wanna see stderrs of hanging tasks.
There is update for "team" AK_v8 that will exit after checkpointing when it detects that CUDA not running. So, if CUDA task finishes, one of AK_v8 will exit with zero status.
BOINC will restart it then allowing CUDA app to run.
So, there should be no situations described by Jason now.
ADDON: here is update:
