We will report on a cluster of workstations at our department, called Parnass. It is based on different types of MIPS processor workstations and servers, connected by a Myrinet, a Gigabit per second switched LAN, and additionally a Fast Ethernet. We have ported some low level message passing libraries as well as MPI to the Myrinet. A comparison of the performance of various communication libraries on different networks will be presented.
