PVM

Description

PVM (Parallel Virtual Machine), is a software package that allows a programmer to create and access a concurrent computing system made from networks of loosely coupled processing elements.

Version

 3.4

Installed on
  • linux cluster

    • Executables

    		/usr/local/pvm
    /usr/bin/pvm

    Using PVM on Linux Clusters

    		If you have large jobs to run, please run them on the reindeer or archipelagos clusters. Otherwise, please run your jobs outside of peak usage times in 1111 and 1171.

    Setting up keys

    		To run parallel jobs, use the following steps:
    1. ssh to kepler.berkeley.edu
    2. cd ~/.ssh2
    3. ssh-keygen kepler
      You will be prompted for a passphrase. Choose you passphrase carefully! Do not re-use your password. It defeats the purpose. Two files will be created: 
         ~/.ssh2/kepler      Your private key.
   ~/.ssh2/kepler.pub  Your public key.  Can be shared.
    4. pico ~/.ssh2/identification and put in the following
      IdKey kepler
    5. pico ~/.ssh2/authorization and put in the following
      Key kepler.pub
    6. Start ssh-agent by issuing: ssh-agent /bin/tcsh
    7. Add your key to the agent: ssh-add
      You'll be prompted for your passphrase.
    8. ssh machinename.decf.berkeley.edu
      You SHOULD NOT be prompted for a passphrase.
    9. Log out of client

    Starting PVM

    1. pvm
    2. add hostname
    3. Your application must reside in ~HOME/pvm3/bin/LINUX/
