Abstract
Performance evaluation of parallel applications on an HPC machine is complicated. However, modeling the main factors of single processor performance and communication performance among processors is usually sufficient for application performance evaluation. This paper describes the performance measurements of our SMP POWER4 machines p690 and -655 using the PMaC benchmark suite.
