[AMBER-Developers] Request for testing new cuda code updates

Hi everyone:

Dave Cerutti has added some new CUDA code (commit
4596dbe1571a33581f04f), that adds Turing and Volta-related updates to
the CUDA codes. It adds support for CUDA 10, and gets optimized codes
for Volta and Turing without the need for any user flags (like the '-volta'
flag that used to be needed).

I'm asking developers that use CUDA codes to update their master branch,
recompile pmemd.cuda, and see if you find any problems on jobs you are
running as a part of your ordinary work. These changes will probably
become an update to Amber18, but we want to give them a workout
ourselves before unleashing them on the world. (They pass all the test
cases, but I'd like to get them exposed to a wider variety of problems as

If you are interested in performance issues and have the time, reported
before/after timings, especially on Volta and Turning, would be useful.
