  abstract = {We report on a cluster with 96 CPUs (48 Dual-Processor PCs
		  running Linux 2.1.127) at our department, called Parnass2.
		  The computing nodes are connected by a Myrinet, a Gigabit
		  per second switched LAN, and additionally by a
		  Fast-Ethernet. A comparison of different message passing
		  (MPI) libraries for the Myrinet is given. Furthermore, we
		  present the performance results of Parnass2 for some of the
		  parallel codes developed at our department, namely a sparse
		  grid code for PDEs, a particle code for molecular dynamics,
		  a finite difference code for the Navier-Stokes equation,
		  and a parallel adaptive finite element / finite difference
		  multi-grid code. We compare these results with the
		  performance of these codes running on a Cray T3E-1200, a
		  Cray T3E-600, a SGI Origin 200/2000 and Parnass
		  \cite{MGriebel:GWZumbusch:1997a}, a cluster of SGI O2
		  workstations.}
