PVM is a software system that enables a collection of heterogeneous
computers to be used as a coherent and flexible concurrent
computational resource.

The individual computers may be shared- or local-memory
multiprocessors, vector supercomputers, specialized graphics engines,
or scalar workstations, that may be interconnected by a variety of
networks, such as ethernet, FDDI. User programs written in C, C++ or
Fortran access PVM through library routines.

After installation you find in /usr/share/doc/packages/pvm/ the
documentation as PostScript file pvm-book.ps. Furthermore some
examples are packed together in two tar archives. Those archives
should be extracted into your HOME directory which leads to
~/pvm3/examples/ or ~/pvm3/gexamples/ in your HOME directory. The call
`aimk all' (see manual page aimk(1)) e.g. in ~/pvm3/examples/ compiles
the examples for the PVM system.
