Presentation Transcript

  1. AMMPI - Summary • Active Messages–2 (AM) implementation over MPI version 1.1 • Porting is trivial - works on virtually any platform that has MPI 1.1 • Often provides very high performance – vendors tune their MPI well • Linux/Myrinet, MPICH, IBM SP3, Origin 2000, Cray T3E, many others… • Based on the AMUDP code base, same cool features • Robust, clear error reporting for ease of debugging • SPMD bootstrapping library (but we use site-specific mpirun) • Network performance/utilization monitoring API • MPI Interface • Non-blocking sends, non-blocking receives • Uses MPI communicators to co-exist happily with other MPI-aware layers

  2. Good Bad AMMPI – Latency Performance minimal small message, round-trip time measured from application

  3. Bad Good AMMPI – Bandwidth Performance with 64 KB messages == MAX_MEDIUM == MAX_LONG

  4. AMMPI – Raw Performance Data
