Cluster Ohio Cluster
The Cluster Ohio cluster is configured with a head node cohn.cs.kent.edu.
This is the only node that can be logged into directly (using ssh).
It is a 700MHz Celeron processor with 256MB of memory. It should only be used to access the cluster, not to
run computations.

The computational cluster has eight nodes each consisting of:
- Four, 550 Megahertz Intel
Pentium III Xeon processors, with
- 512kB of secondary
cache
- Two Gigabytes of RAM
- 18 Gigabytes, ultra-wide SCSI hard drives
- Two Myrinet interfaces- only one of these is currently active
- One 100Base-T Ethernet
interface
- RedHat
Linux
- Portland Group Compilers for
FORTRAN
- KAI Toolset for C, and C++
- Etnus
Totalview
- NAGlib
- Miscellaneous tools from the
public domain or OSC developed.

MPI configuration
The Cluster Ohio cluster runs LAM. Nodes may be accessed over the 100Mbps Ethernet or the Myrinet network.
Over the 100Mbps network, the computational nodes are addressed as node1, node2, node3, node4, node5, node6, node7 and node8.
Over the Myrinet network, the computational nodes are addressed as mnode1, mnode2, mnode3, mnode4, mnode5, mnode6,
mnode7 and mnode8.
Note that these are on two private networks 192.168.1.0 and 192.168.2.0 respectively and thus may
only be accessed through the head node cohn.cs.kent.edu.
