Abstract

The process of obtaining useful message passing applications tracefiles for performance analysis in supercomputers is a large and tedious task. When using hundreds or thousands of processors, the tracefile size can grow up to 10 or 20 GB. It is clear that analyzing or even storing these large traces is a problem. The methodology we have developed and implemented performs an automatic analysis that can be applied to huge tracefiles, which obtains its internal structure and selects meaningful parts of the tracefile. The paper presents the methodology and results we have obtained from real applications.
