Advantages of PVM over sockets:

-portable software between
	-UNIX and dedecated MPP machines
	-different flavours of sockets
-transparent interoperability between
	-heterogeneous machines
	-heterogeneous software
	-TCP/IP and dedecated MPP machines
-one-line remote process creation
-fault detection
-multicast
-striding array packing

And using some of the extra goodies that people are building on top of
PVM:

-load balancing & resource management (several versions)
-assorted matehmaitcal libraries
-optimistic programming (soon, I'm working on it :-)
