UWM LSC Group Beowulf System UWM LSC Home Page > Beowulf System

The Center for Gravitation and Cosmology is a research group within the Physics Department at the University of Wisconsin - Milwaukee (UWM). Within this center is a group of researchers working on the LIGO Experiment, a large national project to detect and study gravitational waves, as part of the LIGO Scientific Collaboration (LSC). The work of the UWM LSC group is centered on the analysis of LIGO data.

This analysis is extremely computation-intensive, and benchmarking studies carried out the by the UWM LSC group and researchers at Caltech have indicated that Beowulf-type machines are the most cost-effective way to carry out LIGO's data analysis. Many of the algorithms being developed for this analysis are being tested on data from a prototype experiment (the 40-meter detector) and the UWM LSC group has set up a Beowulf machine to use for this purpose.

Medusa: The 300 Node Beowulf

Medusa web pages
The medusa web pages provide a complete description of the design and maintenance of the cluster. There is also a record of the benchmarking, construction and commissioning process.

We have received a grant from the NSF to construct a 300 node beowulf system for LIGO related data analysis. The system is comissioned and bulit and is now servicing our users.


48 Node DEC Alpha Beowulf

The 48 Node DEC Alpha Beowulf
Constructed 4th May 1998

Our old Beowulf has 48 nodes connected by a 100-base T switch. Each node is a DEC 300XL workstation containing a 300 MHz alpha 21164 CPU with 2Mbytes of cache, and a peak floating point performance of 600 Mflops. The system has a peak floating point performance of 28.8 Gflops, 8.45 Gbytes of distributed RAM, and 98 Gbytes of distributed disk storage space.
