Abstract : |
Communication between multiple partitions of a multiprocessor facilitates the implementation of multidisciplinary applications representative of many grand challenge problems of the High Performance Computing and Communications Program (HPCCP). An extremely fast and efficient Intercube Communication Library has been developed to support communication between multiple partitions (allocated cubes) on the Intel iPSC/860. A tool which provides performance data in this context is invaluable to the application developer attempting to identify performance bottlenecks and allocate computational resources to achieve load-balancing. This paper describes how the Automated Instrumentation and Monitoring System (AIMS), a software toolkit that facilitates performance evaluation of parallel applications, has been extended to enable intercube programs to be monitored and visualized., |
