Message-passing systems are typically used to achieve high-performance parallel
computing. In this paper we examine how advanced concurrent programming can be
achieved using existing message-passing systems. In particular, we look at
Reppy's extension to Hoare's basic CSP model, called higher-order
concurrency, where communication events (such as send, receive and
non-deterministic choice) are first-class just like normal program variables
(e.g., integers), that is, they can be created at run-time, assigned to
variables, and passed to and returned from functions. This allows the
construction of high-level concurrent features without explicit support for
them in the model itself. We see how first-class events can be implemented in
PVM, showing that it forms the base of a powerful concurrent-programming
language. We also provide garbage-collection of processes, which
simplifies selective communication and dealing with end-cases. The
implementation promotes more widespread use of the flexibility present in the
higher-order-concurrency model, and allows multiple processors to be exploited
in such programs.
