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.
The current grid sports 181 nodes with a total of 1820 cores, as detailed in the following table.
|mblade12||20||32||640||64G||160G||Opteron 6282 SE||2.6|
|mblade13||7||64||448||256G (1-3), 128G (4-7)||1T||Opteron 6380||2.5|
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.
Each machine on the grid has a 1Gb switched network connection to the department's core switches, with the following exceptions.
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
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.
These are Dell PowerEdge 1855 blade systems. They were purchased by the department, for the grid.
These are the second round of Dell blade systems purchased for the grid in 2009. They are Dell PowerEdge M610s.
MaxBuilt blades purchased for the grid in 2012.
Nodes 1-7 are Erik Sudderth's research machines. As a grid donor, he and his group have priority access to these machines.
These are Dell PowerEdge 1850 servers, a gift from Pixar in 2007.
These systems were donated to the department by an alum.
These are Eugene Charniak's research machines. As a grid donor, he and his group have priority access to these machines.
The grid's first high-end multiprocessor, it was purchased for the grid by the department.
This is Maurice Herlihy's research machine. As a grid donor, he and his group have priority access to it.
The grid's second high-end multiprocessor, it was purchased for the grid by the department.
A former high-end desktop machine repurposed for grid use.
