One possible drawback of your mod, and the way it bypasses BOINC's knowledge of CUDA: it doesn't do task-switching very well - I've already found it trying to run 5 x CPU and 0 x GPU a couple of times. Easy to manage with task suspension, but it still means babysitting.

If only SETI MB used - all will be fine - always 4+1. If you will use AP too - things bacome complicated - yes, 5+0 possible (if no free SETI MB tasks) And if another project is used too, well, chances to get 5+0 increase. It could be solved by increasing SETI project share.
Sure task scheduling is BOINC job, no science app job. And my mod just works instead BOINC now.
Raistmer:
This is replacement for CUDA part of V8 of my package. This build has VLAR autokill ability.
You need to decompress this file into SETI project directory (when BOINC switched off of course) if you don't want process VLAR on CUDA.
That is, if VLAR task goes to CPU app - it will be processed. If it goes to CUDA app - task will be aborted with error (BAD_HEADER).
EDIT: There was wrong file name (.exe twice). Archive replaced, please, remove secondary .exe by renaming manually or download new archive.

Raistmer:
V8a update available.
Changes:
- VLAR autokill mod enabled for CUDA app
- PGO redone for CPU app
- Wall-clock elapsed time since last restart (or since start of task) is added to stderr for both apps.

AMD SSE3 (X2 Athlon ) working on this build ?

No, will do SSE3 soon.
BTW, does anyone need SSE2 and low ?
That is, does anybody have SSE2-only CPU with CUDA-enabled GPU ?
