Parnass consists of a total of 49 (37) processors, some of them are single processors and some shared memory dual processors clustered to 4 processor shared memory machines.The single processor O2 workstation is equiped with 64 - 256Mbytes and the dual processors Origin 200 are equiped with 192 Mbytes main memory. Each processor contains 0.5-1 Mbyte second level cache and 32+32 kbytes instruction anddata first level cache. See the original pages the project pages and the network description for details.
The nodes are connected by a high performance Myrinet network
at the speed of 1.28 Gbit/s duplex. The network adapters are connected
by a two plane fat tree structure of full crossbar Myricom 8 port
switches. Additionally the nodes are connected by fast ethernet.
The peak performance of Parnass is 22.4 GFlop/s. Parnass has 4.2 Gbytes
of main memory and about 150 Gbytes of hard disk storage. Parnass is used
for research on and education in parallel and distributed computing in
projects on fluid dynamcis (Navier-Stokes,turbulence simulation), astrophysics
(MHD), geology (surface flow), molecular dynamics (Multipole) and parallel
algorithms (multilevel).
There is a total amount of 27 Gbytes main memory and about 560 Gbytes hard disk storage. The system accounts for 51.2 GFlop/s. Furthermore, in real applications the new system Parnass2 is much faster than the original Parnass, see the performance pages. This is in part due to the fact that the system is dedicated to parallel computing, but basically network and integer computing performance are much better.
