2.2 Loading the PVM Software

This section describes how to load the PVM software onto each PVM cluster member.

2.2.1 Deleting Existing PVM Software Subsets

Before loading a new version of the PVM software, any previous versions of the software must be deleted.

*** To test that the compiled PVM program runs successfully
*** (and prints an approximation of 'pi'),
*** you may, as a non-privileged user:
    % dpvm
    dpvm> quit

    %/tmp/mb_pi.dpvm -numprocs 4
