tau_poe — Instruments a MPI application while it is being executed with poe.
This tool dynamically instruments a mpi application by loading a specific mpi library file.
To instrument a mpi application a specific TAU library file is loaded when the
application is executed.
To select which library is loaded use this option. The library files are build
according to the options set when TAU is configured. The library file that have
been build and thus available for use are in the [TAU_HOME]/[arch]/lib directory. The
file are listed as libTAUsh-*.so where * is the instrumentation options. For
example to use the libTAUsh-pdt-openmp-opari.so file let the comman line
option be -XrunTAUsh-pdt-openmp-opari.
