Ralph Castain 6509f60929 Complete the memprobe support. This provides a new scaling tool called "mpi_memprobe" that samples the memory footprint of the local daemon and the client procs, and then reports the results. The output contains the footprint of the daemon on each node, plus the average footprint of the client procs on that node. ... Samples are taken after MPI_Init, and then again after MPI_Barrier. This allows the user to see memory consumption caused by add_procs, as well as any modex contribution from forming connections if pmix_base_async_modex is given. Using the probe simply involves executing it via mpirun, with however many copies you want per node. Example: $ mpirun -npernode 2 ./mpi_memprobe Sampling memory usage after MPI_Init Data for node rhc001 Daemon: 12.483398 Client: 6.514648 Data for node rhc002 Daemon: 11.865234 Client: 4.643555 Sampling memory usage after MPI_Barrier Data for node rhc001 Daemon: 12.520508 Client: 6.576660 Data for node rhc002 Daemon: 11.879883 Client: 4.703125 Note that the client value on node rhc001 is larger - this is where rank=0 is housed, and apparently it gets a larger footprint for some reason.
