Jeff Buell, who is working full time on characterizing HPC workloads on our virtualization platform, has posted a new blog entry on the VROOM! Blog. This one focuses on NAMD performance. In particular, his experiments focus on some small test cases running NAMD using MPI over TCP/IP.
We are in the process of acquiring a small cluster with QDR InfiniBand and 10 GbE to allow further testing of parallel distributed applications in a virtual environment. What Jeff is reporting here is the start of a larger effort.
