##
## test_case_run_mpi_app
## ---------------------
## run an mpi application initiated by host with host_list processes
##
## Usage:
##	test_case_run_mpi_app host host_list timelimit dir mpi_cmd [mpi_args] [show_perf] [case_tag]
## Arguments:
##	mpitype - mvapich1, mvapich2, openmpi, intel, or variations
##	transport - transport layer for MPI, choices are:
##					For intel_mpi: sock or rdma
##					For others: default
##	host - host to initiate mpi run
##	host_list - hosts/processes to run
##	dir - directory (if not absolute assumed relative to tests_dir) with command
##	timelimit - time to allow between output by command
##	mpi_cmd - MPI appl command
##	mpi_args - application args
##	show_perf - should results be shown as performance
##	case_tag - suffix for test case name, default is mpi_cmd argument value
## Returns:
## Additional Information:
##	must be used within a test_suite's body, performs test_case calls
##	uses case_setup and case_cleanup provided by caller
##	no item_setup nor item_cleanup used
