This directory contains programs and tests that need to be run by
a human being rather than a script.  Instructions on running each test
are in the test file at the top.

singjoin - A test of Comm_join, including a test of comm_join by singleton
           processes

testconnect - A test of Comm_connect and Comm_accept, with many processes.
              Use the script manyconnect to run them, as in

make testconnect
./manyconnect

dimsbalanced - A test of MPI_Dims_create; this checks that Dims_create 
               produces well-balanced results.  Since there are no 
               requirements on the "balance" of the output of Dims_create,
               this is a test of the quality of implementation of the
               default MPI_Dims_create when there is no underlying 
               network topology.

spawntest_master, spawntest_child - A test of MPI_Comm_disconnect to ensure
		  that once processes are disconnected, one can proceed
		  through MPI_Finalize without waiting for the other to
		  also proceed through MPI_Finalize.  This test is 
		  designed to succeed even if either the child or master
		  waits for the other in MPI_Finalize.  If MPI_Comm_disconnect
		  works correctly, the spawned children (4 by default), 
		  should exit roughly 30 seconds before the master.
