The strace output I/O analyser is a tool to analyze the I/O behaviour of serial and parallel applications. It traces the system calls and generates statistics for every accessed file.
The process is described in https://github.com/cniethammer/strace-analyzer.
The tool consists of two parts: a trace wrapper and an analysis tool. The wrapper is used to generates a set of strace log files - one for each MPI process. The log files will be stored in a directory strace-logs under the current path and can be analysed with the analysis tool.
