Abstract
The PAPS (Performance Analysis of Parallel Systems) toolset is a testbed for the model based performance prediction of message passing parallel applications executed on private memory multiprocessor computer systems. PAPS allows to describe the execution behavior of the computer hardware and operating system software resources up to a very detailed level. This enables very accurate performance prediction of parallel applications even in the case of substantial performance degradation due to contention for shared resources. In this paper the fundamental design principles and implementation methodologies for the development of the PAPS toolset are presented and the PAPS parallel system specification formalisms are described. A simplified performance study of a parallel Gaussian elimination application on the nCUBE 2 multiprocessor system is used to demonstrate the usage of the tool.
