A Synchronized Real-Time Linux Based Myrinet Cluster for Deterministic High Performance Computing and MPI/RT
Overview This paper describes the design and implementation of a real-time cluster of PCs that provides globally synchronized scheduling and predictable messaging passing. A high-accuracy, fine-grain global clock implementation has been closely coupled with a time-based scheduler to facilitate finely synchronized global scheduling across the cluster. A real-time messaging layer provides predictable communication latencies over the interconnecting Myrinet network. This system provides a solid framework for QoS based real-time communication, and in particular facilitates efficient layering of high-performance real-time distributed middleware such as MPI/RT. This paper present experiments and results to demonstrate the degree of predictability and synchronization achieved on an 8-node Myrinet cluster.
