Beowulf Hardware Overview

Helios Hardware Layout
The Helios cluster, also known as the production cluster, currently consists of 18 machines: In terms of networking equipment, there are a total of three switches: The Category 6 Ethernet cables are color coded: (G) Gateway ethernet connections: (A) Admin ethernet connections: (N) Nodes: ProCurve Switch: Each BayStack switches:
 * (G) A 1GHz AMD Athlon(tm) 64 X2 Dual Core Processor 3800+-based machine with 2 GB RAM.
 * (17) A 3GHz AMD Athlon Dual Core Processor with 8 GB RAM that serves as a large computation node
 * (N) Sixteen Sun Fire x2100s w/ 2048MB RAM that serves as the computational nodes.
 * An HP ProCurve 2824 24-port gigabit switch
 * Two Bay Networks BayStack 304 switches for the management network
 * Green cables represent non-computational network traffic
 * Blue cables represent connections between switches
 * Yellow cables represent computational traffic
 * Red cables represent management traffic (OS independent)
 * Green cable to the ethernet
 * Green cable to the admin machine
 * Green cable to the gateway machine
 * Green cable to the ProCurve switch
 * Red cables to one of two BayStack switches
 * Yellow cables to the ProCurve switch
 * Blue cables to both of the BayStack switches
 * Green cable to the admin machine
 * Yellow cables to each of the nodes
 * Blue cable to the ProCurve switch
 * Red cables to half of the nodes

Castaway Hardware Layout
The Castaway cluster, also known as the development cluster, currently consists of 28 machines, but has been depreciated and dismantled in favor of Mist-rider and Cumulus: In terms of networking equipment, there are a total of two switches:
 * (GA) A AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ 2.0 GHz PC with 2 Gb RAM
 * (N) Twenty-six Gateway Pentium III 933MHz w/ 256MB RAM that serves as the computational nodes.
 * A Dell PowerConnect 2016 16-port 100Mbit switch (Currently nonfunctional)
 * A D-Link DES-1024D 24-port 100Mbit switch (Now being used for cumulus)

Cumulus Hardware Layout
The Cumulus Cluster, currently in development, consists of the old Mist-Rider machines. Networking
 * (N) HP Workstations with Intel(R) Core(TM)2 Quad CPU Q9450 @ 2.66GHz and 4GB of RAM
 * A D-Link DES-1024D 24-port 100Mbit switch (Originally from Castaway)

High Bandwidth Cluster
The High Bandwidth Cluster consists of old Mist-Rider Nodes as well as the three Thing machines using Infiband (Summer 2014). Networking
 * (N) HP Workstations with Intel(R) Core(TM)2 Quad CPU Q9450 @ 2.66GHz and 4GB of RAM
 * Switch borrowed from IT (New switch to be requested?)
