In the last year's IEEE Micro special issue on the Hot Interconnects IV Symposium, we discussed our experiences with client-server computing on the Paragon-based Shrimp multicomputer. Since then we implemented the same virtual memory-mapped communication (VMMC) mechanism on the Myrinet-based Shrimp multicomputer (a set of Pentium PCs connected by a Myrinet network). In both cases we achieved protected, user-level, end-to-end performance close to the hardware limits. However, VMMC imposes a copy for high-level connection-oriented communication libraries. Therefore, we extended the VMMC model, and designed and built a new implementation. We call the new model VMMCII. This update reports our latest work with VMMCII on the Myrinet-based Shrimp multicomputer.
