Example 10-3 Example of Running and Binding Programs in Psets
List the current Pset configuration for the local nPartition. Two Psets are
configured: Pset 0 and Pset 2.
Note that processor ID 10 is not active in this nPartition (because iCOD
software has deactivated it).

Use the mpsched command to run the “potato” program and bind it to
processor ID 2. Then use the psrset -q... command to list the Pset
binding for “potato” (process ID 10368); “potato” is bound to Pset 0.
# mpsched -c 2 ./potato -n 7
Pid 10368: bound to processor 2 using the default process launch policy
