Abstract HDTrace is an environment which allows to trace and simulate the behavior of MPI programs on a cluster. It explicitly includes support to trace internals of MPICH2 and the parallel file system PVFS. With this support it enables to localize inefficiencies, to con-duct research on new algorithms and to evaluate future systems. Simulation provides upper bounds of expected performance and helps to assess observed performance as potential performance gains of optimizations can be approximated. In this paper the environment is introduced and several examples depict how it assists to reveal inter-nal behavior and spot bottlenecks. In an example with PVFS the inefficient write-out of a matrix diagonal could be either identified by inspecti...
