I have been a long time SETI and Einstein cruncher. With SETI going into hibernation, I have joined MW to fill the void. I have 3 boxes with Nvidia GPU cards (2 with GTX-760 and 1 with GTX-1050Ti). i have read in other posts that Nvidia GPU cards don't process MW GPU work units efficiently. Is this still true? My plan is to limit Einstein WU to the GPU cards and limit MW WU to the CPU. Does this sound like a good plan, or should I just let both projects run both CPU and GPU WU?

This is a fallacy promoted by dedicated MW volunteers of long standing. Their opinion is simply based on the better dual precision FP64 ratings of AMD cards at cheaper prices than equivalent Nvidia cards. The AMD application is also better at running multiple tasks per card compared to Nvidia cards. If you are starting crunching MW from square one and have not purchased any gpu yet, then AMD cards are recommended.

However if you already own Nvidia cards, then they are perfectly capable of crunching MW with similar but slightly longer crunch times compared to AMD. And ANY gpu is more efficient at crunching ANY task compared to a cpu. So run both cpu and gpu tasks for MW and Einstein on your Nvidia cards and don't worry about it.

Ron -

I only see 2 or your 3 computers listed. If your third (unlisted) computer has at least 2GB of video card memory you are OK for Einstein GPU tasks.

Take note in your planning that Einstein "GPU tasks" actually use 1 CPU and 1 GPU.

In any case, try things and see what happens.
