Re: Amicable Numbers GPU App
With a little help from the admin i figured out why my times sucked so bad.
My XEON CPU's are too slow to keep the GPU feed with just 1 WU and reserving more CPU's does not help as it appears the GPU app is single threaded.
I am now running 3 WU's on my 1070 and 4WU's on a 1080 and it appears to be working correctly now.
each WU gets its own CPU thread.
Re: Amicable Numbers GPU App
That's a really good thing to know KB since I have similar Xeon machines. My single GTX 1080 is running in a 4.2G I7 and a single WU keeps the GPU at 100% load. Another intersting thing is the I7 is PCIe 2.0 and your Xeon MB is PCIe 3 so it should be quicker.

All 7 of my gpu's on it for the upcomming challenge.... Cant bunker too well, server only gives 20 work units per gpu...

Why don't you throw 20 GPUs in each box? HERE

Did you even bother to look at the link Doug?
Re: Amicable Numbers GPU App
Having to run 8 WU per 1080 to keep usage up now.
FYI my xeons are downclocked to 1.9GHz due to using AVX.

Yes, too complicated to build a co_proc, for my feeble mind!

So, you didn't read to the very last line then Doug. :))
