Abstract
--------

Asynchronous distributed computing is an important
and effective technique for many scientific applications.
This paper describes the design and implementation of asynchronous
communication library routines for distributed computing
across networks of workstations.
The new system is based on modifications of the existing
PVM message-passing environment. An intensive and comparative
study of synchronous, asynchronous and non-blocking communication
protocols is addressed in terms of their design, implementation and
applications. Experimental performance comparisons of an application
program using the three communication protocols
on a network of workstations, are also presented.
The experimental results show the
power of the asynchronous communication library and the
effective enhancements of the PVM message-passing environment.
