This hypertext document is intended to provide photographs, descriptions, and contact information for the various sites using Linux systems for parallel processing. Each parallel system is listed in approximate reverse chronological order, i.e., the system that became operational most recently is listed first. To have information about your site posted here:



School of Electrical and Computer Engineering,
Purdue University

Date System Became Operational
November 1996
Hardware Parallelism & Interconnect Structure
16 Linux machines connected by five PAPERS 960801 modules
Hardware Configuration
Eight identical IBM 386DX25 PS2 Model 70, 4M RAM, 250M disk, VGA display; eight identical Intel 386DX33, 8M RAM, 250M disk, Ethernet, VGA display; 4x4 monitor VGA display array
Primary Use Of System
To prove that the field-scalable PAPERS 960801 design really works and to develop/test software, including PEN (the PAPERS ENvironment that serves as a meta-OS across the Linux systems). The 386DX25 PS2 systems are too slow for much beyond driving the VGA video wall for demos and some scientific visualization.

Hub
Cluster

Computer Science,
Cornell University

Date System Became Operational
January 1996
Hardware Parallelism & Interconnect Structure
4 Linux machines connected by 100 Mbps Ethernet
Hardware Configuration
Pentium 133, 16M RAM, 1G disk, DECChip 21140 Fast Ethernet, SVGA; Pentium 90, 32M RAM, 2G disk, DECChip 21140 Fast Ethernet, SVGA; Pentium 133, 32M RAM, 1G disk, DECChip 21140 Fast Ethernet, SVGA; SMP 2-processor Pentium 133, 64M RAM, 13G disk, DECChip 21140 Fast Ethernet, SVGA; Intel Express 10/100 Hub
Primary Use Of System
This is an experimental set-up for clustered computing using the U-Net interface over Fast Ethernet. The state of the machines of the cluster (and their connectivity) are always in flux: one of the machines participates in the U-Net ATM cluster (along with 12 or so SparcStations). Planned upgrade to a more permanent set-up involving P6 workstations and a Fast Ethernet switch.
