I really like the AMI. Some details would help here, such as your run command, number of processors invoked, and benchmark statistics. The gpu tutorial gives a good primer on benchmarking cuda-accelerated runs.

I am trying to run the namd AMI package and I'm not getting very good performance. I've tried a few types of p2 and p3 node types and I can't get comparable performance to my university's HPC clusters when running 2 workloads on the same node. ~200000 atom system. The performance doesn't appear to be very different from copying over the precompiled binary from the website. Just wondering if anyone else has encountered this issue.
Completely possible I'm just not running things in the correct way, so I would be very interested to see how you guys run things.
