The MPITrace system is based on the concept of a Regular Section Descriptor (RSD) [2]. These RSD's are extended in the MPI trace system to accomodate nested loops in [1]. RSD's can be used to perform loop compressions. The extensions to RSD enable internode compression of function calls.
These structures are coded into the MPICTrace program, and are used to record and replay the MPI calls for a program.
