PETSc can gather data for use with the utilities Jumpshot (part of the MPICH distribution). If PETSc has been compiled with flag -DPETSC_HAVE_MPE (MPE is an additional utility within MPICH), the user can employ another command line option, -log_mpe, to create a logfile, "mpe.log", which can be visualized Jumpshot.
