Traditional way to analyze performance of message passing (MPI) applications is via visualization of their execution traces. Several tools were developed to aid this activity; one example of such tool is Jumpshot. However, performance analysis with such tools is a complex task due to large traces and complex interactions between processes. In this paper a new way to analyze performance is proposed by automatic detection of performance problems in message passing applications. Performance problem is defined as a set of actions that inhibit good performance and is specified using tracing and analysis rules. Keywords: performance problems specification, performance problems detection, message passing applications.
