PVM (Parallel Virtual Machine) is a software package
that permits a heterogeneous collection of Unix and/or Windows computers
hooked together by a network to be used as a single large parallel computer.
Thus large computational problems can be solved more cost effectively
by using the aggregate power and memory of many computers.
The software is very portable. The source, which is available free thru netlib,
has been compiled on everything from laptops to CRAYs.
PVM enables users to exploit their existing computer
hardware to solve much larger problems at minimal additional cost.
Hundreds of sites around the world are using PVM to
solve important scientific, industrial, and medical problems
in addition to PVM's use as an educational tool to teach parallel programming.
With tens of thousands of users, PVM has become the de facto standard
for distributed computing world-wide.

Compile problem with Redhat 7.0 and PVM 3.4.3. Redhat changed the way
compilers work between 6.x and 7.0 that causes an error message on compile.
The fix is simple and can be applied manually:
You need to change 2 lines in pvm3/src/lpvmpack.c as follows:
line 1827: tc = (char) va_arg(ap, int);
line 1852: th = (short) va_arg(ap, int);
then recompile. That should do it.
This fix is in the PVM 3.4.4 and later releases.
