Running PVM programs on your PC or laptop is the same as on the cluster except you would not be using the PBS system. You can use pvm console or xpvm directly. Note that all the processes in your parallel program will run on your machine so you will not see any speedup (unless you have more than one CPU!). However this is an excellent way to develop and test your code. You can often resolve 90% to 95% of problems by running and testing on a single machine.
