Abstract:
Although PVM was developed to use a network of heterogeneous
UNIX computers as a single large parallel computer,
it has become an interface for portable programming even on MPP's.
We present PVM performance results for a massively parallel
transputer system with up to 512 processors.
In comparison to an implementation of the same application
in the native transputer operating system Parix,
we realized about 30% performance loss for the
PVM application.
This is mainly caused by restrictions in the process model
and the less efficient communication of PVM in comparison to
Parix.
