FahBench with OpenMM 6.1

It seems that a lot of GPU problems revolve around specific versions of drivers. Though AMD has their own support structure, you can often learn from information reported by others who fold.

FahBench with OpenMM 6.1

Postby foldy » Sat Oct 18, 2014 4:41 pm

I did a compile of FahBench with new released OpenMM 6.1
Currently OpenMM 5.1 is part of FahCore17.
But i wanted to test if there would be a performance improvement in just using OpenMM 6.1

Tested AMD 14.9 driver with FAHbench on my HD 7950 @ 900Mhz (equals AMD R9 280)

OpenMM 5.1 (FahCore17)
Explicit 35
Implicit 122

OpenMM 6.1 (FahCore ???)
Explicit 35
Implicit 150

So this is an improvement in Implicit by 23% :-)

I also tested with a real work unit as scratch data and it also showed a 20% speedup.
