A monitoring system for a transputer-based multiprocessor
Mats Aspnäs, Thomas Långbacka · 1991
This paper describes a distributed performance monitoring system for a transputer-based multiprocessor, Hathi-2. The monitoring system allows the programmer to measure how well a parallel program utilizes the hardware resources of the multiprocessor system, i.e., the processor CPU's and communication links, during program execution. It can be used for identifying performance bottlenecks in parallel programs. We present the different components of the system, together with a case study where we monitor an existing application program.
