1) Message boards : Number crunching : pps sieve running 5 at once (Message 102788)
Posted 967 days ago by _heinz
if I run five wu's per gpu on my 3 Titans with appinfo or appconfig BOINC 7.6.33 Shows:
GPU0 5 wu's
GPU1 5 wu's
GPU2 4 wu's
It runs on the last GPU allways 4 not 5 wu's Independent if I use appconfig or appinfo. Have no idea why.

Today I started genefer17mega on my 3 Titans without any appconfig or appinfo. The app started on all 3 Titans but run still on gpu0 and gpu1, on gpu3 it hang around and does nothing, later the app changed automatic the gpu and at least it run on gpu0, here you can have a look on the result
resultid=763669663

plese have a look at my host

Win10 killed my machine during the contest. Had to install driver again with several new starts. Installing EVGA Precision again and so on. Lost 2 hours today.

Intel Atom NVIDIA ION (256MB) driver: 34052
65,894.21 sec/wu

surely the slowest GPU, but it does it.

I have app_info running 4 at once on my three Titans also together 12 wu's at once. It would be nice to have an entry to add all my cpu's too. Till now they do nothing.
In Top Computers I'm at place 3 now (without any CPU working wu's).
