Re: [AMBER] CUDA 10.0 vs CUDA 9.2 for Amber18&1080Ti GTX - any gain in performance?

Hi Nick,

CUDA 10.0 is not yet supported. There will need to be modifications to the AMBER source code to support it.

As such there is no comparison available yet between CUDA 10.0 and 9.2. If history serves as a guide though you can generally expect to see about a 5% decrease (yes decrease) in performance when going to a newer CUDA compiler.

Note Turing works fine with CUDA 9.2. Just compile with sm_61 and it will run on the RTX cards no problem. Note AMBER 18 needs a few tweaks to get optimum performance on RTX cards though. A patch will be coming shortly.

All the best
Ross
