Grid Resources

Grid

Our grid contains a variety of machine configurations, from basic dual-core systems to large-memory multiprocessors. All systems are accessible to all members of the CS community for research or educational purposes.

All machines mount the department's filesystems. All are on the department's network, but some are better connected than others. See the networking notes below. Access to the machines is restricted to the gridengine software.

Dedicated Machines

The current grid sports 182 nodes with a total of 1828 cores, as detailed in the following table.

In the table above, where there are multiple machines of a type, hostnames end with a number (e.g. dblade17).

All machines are running 64-bit Debian Linux.

Networking

Each machine on the grid has a 1Gb switched network connection to the department's core switches, with the following exceptions.

Angstrom Rack

The "ang" machines are split evenly between two dedicated switches, each of which has a single 1Gb uplink to the department's core switches.

History / Provenance

bench

These are MaxBuilt (tstaff) systems originally added to the grid to provide a separate benchmarking platform. Since that's no longer necessary, they are just additional resources.

dblade

These are Dell PowerEdge 1855 blade systems. They were purchased by the department, for the grid.

blade09

These are the second round of Dell blade systems purchased for the grid in 2009. They are Dell PowerEdge M610s.

mblade12

MaxBuilt blades purchased for the grid in 2012.

mblade13

Nodes 1-7 are Erik Sudderth's research machines. As a grid donor, he and his group have priority access to these machines.

dpe07

These are Dell PowerEdge 1850 servers, a gift from Pixar in 2007.

ang

These systems were donated to the department by an alum.

ec

These are Eugene Charniak's research machines. As a grid donor, he and his group have priority access to these machines.

rockyroad

The grid's first high-end multiprocessor, it was purchased for the grid by the department.

sandpiper

This is Maurice Herlihy's research machine. As a grid donor, he and his group have priority access to it.

chunkymonkey

The grid's second high-end multiprocessor, it was purchased for the grid by the department.

arya

A former high-end desktop machine repurposed for grid use.

tron

A retired server.
