Here’s a quick set of steps for testing PVM without having all of OSCAR installed.

  1. Install the PVM rpm(s) (If you don’t have Env-switcher/Modules installed you can set the following environment variables by hand on all systems to be used in the virtual machine, e.g., via $HOME/.profile (BASH) or the appropriate file for your shell.)

    if on x86


    if on x86_64 or ia64


  2. Grab the ‘master1.c’ and ‘slave1.c’ files from the testing/ subdir of the PVM opkg.
  3. Compile the test programs,

    sgrundy: $ gcc -I$PVM_ROOT/include master1.c
    -L$PVM_ROOT/lib/$PVM_ARCH -lpvm3 -o master1

    sgrundy: $ gcc -I$PVM_ROOT/include slave1.c
    -L$PVM_ROOT/lib/$PVM_ARCH -lpvm3 -o slave1

  4. Create the default location for PVM binaries,

    sgrundy: $ mkdir -p $HOME/pvm3/bin/$PVM_ARCH

  5. Copy the ‘master1’ and ‘slave1’ files to the default PVM binaries location (see above),
      sgrundy: $ cp master1 slave1 $HOME/pvm3/bin/$PVM_ARCH
  6. Startup pvm and add a machine (or two)

    sgrundy: $ pvm pvm> conf #…lists the current virtual machine configuration… pvm> add oscarnode1 pvm> conf # …lists the current virtual machine configuration…

  7. Exit from the pvm console using ‘quit’ (not ‘halt’).

    pvm> quit sgrundy: $

  8. Run the ‘master1’ binary and you should get results for the calculation. (Assuming you have two nodes (localhost and oscarnode1) you would have 6 lines, three values from each machine.) 1.You can now return to the pvm console and halt PVM to end the test.

    sgrundy: $ pvm pvm> halt
