Eine Systemumgebung zum verteilten funktionalen Rechnen

This paper presents the first part of a project to create a system environment for distributed functional programming, suitable for use in the computer algebra system PARSAC-2. 'Distributed Thread System' (DTS) allows a user to distribute a program over a network of loosely coupled workstations. This can lead to significant improvements in program execution time. DTS is based upon Parallel Virtual Machine (PVM) 3.1 and C Threads. It provides functions to start concurrent function calls (threads) which are then automatically spread over the network by the system. DTS can recover from host failures and allows on-the-fly addition and deletion of host from the network. The use of DTS with PARSAC-2 is discussed in part 2 of the project which also presents detailed measurements of a few example distributed PARSAC-2 algorithms and the implementation of a public key cryptosystem. It demonstrates that good speedups can be obtained through using DTS.
