How do I view VampirTrace output?
While OMPI includes VampirTrace instrumentation, it does not provide a tool for viewing OTF trace data. There is simply a primitive otfdump utility in the same directory where other OMPI commands (mpicc, mpirun, etc.) are located. Another simple utility, otfprofile, comes with OTF software and allows you to produce a short profile in LaTeX format from an OTF trace. The main way to view OTF data is with the Vampir tool. Evaluation licenses are available. 8. Are there MPI performance analysis tools for OMPI that I can download for free? The OMPI distribution includes no such tools, but some general MPI tools can be used with OMPI. You can search the Internet for such tools, and we list a few candidates here. For tracing, there are: • MPE (or here) is a software package for MPI programmers. It is associated with MPICH, but works with other MPIs. The Jumpshot trace viewer has similar functionality to Vampir. • Sun Studio Performance Analyzer has MPI tracing support (like Vampir and Jumpsho
