Script description

[test.sh] A general UDP/TCP/MPI test script 
          Usage: % test.sh protocol host1 host2 [port-number]
          Protocols: [udp] UDP communication tests
                     [tcp] TCP communication tests
                     [mpi] MPI communication tests
                     [all] Test all three protocols
          Port-number: Server's listening port number in UPD and TCP tests.
          Example 1 : % test.sh udp gw38 gw39
          UDP communication test between "gw38" and "gw39" with default port nuumber
          Example 2 : % test.sh tcp gw38 gw39 2000
          TCP Tests with port number 2000

[test.lsf] A UDP/TCP/MPI test script for Platform's LSF queuing system.
           Usage: % bsub [bsuboption] test.lsf [protocol]
           Protocols:    [udp] UDP communication tests
                         [tcp] TCP communication tests
                         [mpi] MPI communication tests
                         [all] Test all three protocols
           Bsub-options: [-n 2] Define process number
                         [-oe logfile] Log file for output and error message
                         [-extsche "nodes=2"] Define node number for test
                         [-m "machinelist"] Define machines for test
           Example: bsub -n 2 -oe log.lsf -extsched "nodes=2" -m "gw38 gw39" test.lsf tcp
           TCP tests between hosts gw38 and gw39

[test-all.lsf] Another UDP/TCP/MPI test script for Platform's LSF queuing system. 
               This script tests all three protocols.
               Usage: % bsub < test-all.lsf
               You can modify the test configuration in file "test-all.lsf" between 
               "setting" and "end of setting" part.
