Hi,
I'm glad i asked; i assume that the 5% perf regression applies to
non Amber software, eg, other MD codes ?
Can you provide more details on the perf regression, compiler bug,
etc.? Are there published benchmarks demonstrating the issues?
This information would be useful to those of us forming compute policies
and for communicating both up and down our chains of command.
Thanks for the info and updating
http://ambermd.org/gpus/
with this advice.
