Setting up the Environment

• Become superuser and add the following lines at the end of the /etc/bashrc file in your system. The following lines set up the environment for PVM for all users on the system.

  #-------------------------------------------------------
  #
  # PVM (Parallel Virtual Machine) Setup.
  #
  PVM_ARCH=LINUXI386
  export PVM_ARCH
  PVM_ROOT=/usr/share/pvm3
  export PVM_ROOT
  MANPATH=$MANPATH:$PVM_ROOT/man
  export MANPATH
  PVM_DPATH=$PVM_ROOT/lib/pvmd
  export PVM_DPATH
  PATH=$PATH:$PVM_ROOT/lib:$HOME/pvm3/bin/$PVM_ARCH:
  export PATH
  XPVM_ROOT=/usr/share/pvm3/xpvm
  export XPVM_ROOT
  PVM_TMP=/tmp
  export PVM_TMP
  #-------------------------------------------------------
  

  Note that the following setup assumes that the PVM software is installed in the directory /usr/share/pvm3, which is true on beowulf.boisestate.edu. If you want to setup PVM on another system, find out where PVM is installed and adjust the directories as needed.

  Now you can either login again for these settings to take effect or source the /etc/bashrc file for the setting to take effect immediately as shown below.

  source /etc/bashrc

  Test out your settings by typing the which pvm command. It should show the path to the pvm control program.

  [amit@kohinoor amit]:which pvm
  /usr/bin/pvm
  [amit@kohinoor amit]:
  

• You will also need to create some directories as follows.

  mkdir ~/pvm3
  mkdir ~/pvm3/bin
  mkdir ~/pvm3/bin/LINUXI386
