From PVM document, speed value doesn't make any different internally.
It's provided to aid the future implementation of some form of task
scheduler in the future. For now, user can set the speed field according to
the relative speed of hosts in their system. Then the application can
call pvm_config() to get the speed and use it to decide how to distribute
the work load properly.
