Thorough Testing


Up: Details Next: Tuning P4 Performance Previous: Managing the servers

The examples/test directory contains subdirectories of small programs that systematically test a large subset of the MPI functions. The command

    make testing 
in the mpich directory will cause these programs to be compiled, linked, executed, and their output to be compared with the expected output. Linking all these test programs takes up considerable space, so you might want to do
    make clean 
in the test directory afterwards. The individual parts of MPI (point-to-point, collective, topology, etc.) can be tested separately by
    make testing 
in the separate subdirectories for examples/test.

If you have a problem, first check the troubleshooting guides and the lists of known problems. If you still need help, send detailed information to [email protected].
