6.4 PVM hosts file

After PVM and Omega are installed, each Omega job run via PVM must be supplied a file (via -pvmconf) that describes the hosts and number of CPU's to use. Each line in this file includes the word ``host'' followed by the hostname of the slave followed by the number of CPU's to use on that slave.

To use 10 slaves on a linux cluster (where nodes are named ``linux1'', ``linux2'', etc.)

host linux1 2
host linux2 2
host linux3 2
host linux4 2
host linux5 2

To use 32 CPU's on a single-image system like an SGI Altix, a single line can be used:

host altix 32
