there is
//limit to 8 GPU's for now
comment in CUDA MB source.
That is, current CUDA MB build can't support more than 8 GPUs per host.

Given Nvidia's issues @ 40nm process....might be a while yet before Quad-GPU on dual PCB.....so luckily not much need for a while.
However, bet we see this from AMD/ATI sooner than we think. ;)

My four computers have been running fine the last 2 hours. Perhaps the electrons just needed to be trained, I don't know. I did download the 3 dll's directly from Seti (fanout) and will try replacing them if I have further problems. Will advise here.
[edit] Just after this post one hung up. Copied in the stock dll's and rebooted. It's running again. Will advise.
[edit again] And another cuda app hung up. Now installed stock app into all 4 machines, rebooted and running again. Will adivse.
Geek@Play:
No Good. :'( :'(
Still looks like the MB_6.08_mod_CUDA_V9.exe is hung up in Boinc Manager. It shows "Waiting to run, .04 cpu's, 1 CUDA". But the GPU temp is still up indicating that it is still running.
I have seen many times in the last hours that the work does complete and starts a new work unit. But it can show as described above at any time.

Jason G:
is that with the older DLL's now?
Geek@Play:
Yes.......now using the older dll's. Also on two of my machines I have had to restart Boinc in order to get the CUDA app going again. Looks like a hard lock up can also occur.
