Grid Resources
|
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 177 nodes with a total of 1380 cores, as detailed in the following table.
| Name | Machines | Cores | Total Cores | Memory | Disk | CPU | Clock |
|---|---|---|---|---|---|---|---|
| bench | 8 | 2 | 16 | 3G | 160G | Athlon 3800+ | 2.0 |
| dblade | 70 | 4 | 280 | 8G | 300G | Xeon | 2.8 |
| blade09 | 16 | 16 | 256 | 24G | 80G | Xeon | 2.4 |
| mblade12 | 20 | 32 | 640 | 64G | 160G | Opteron 6282 SE | 2.6 |
| dpe07 | 5 | 2 | 10 | 8G | 36G | Xeon | 3.4 |
| ang | 51 | 2 | 102 | 12G | 80G | Opteron 250 | 2.4 |
| ec | 2 | 8 | 16 | 16G | 80G | Opteron 870 | 2.0 |
| oriole | 1 | 8 | 8 | 8G | 73G | Xeon | 2.8 |
| tanager | 1 | 4 | 4 | 8G | 73G | Xeon | 2.8 |
| rockyroad | 1 | 8 | 8 | 32G | 80G | Xeon | 3.0 |
| sandpiper | 1 | 16 | 16 | 8G | 80G | Xeon | 2.93 |
| chunkymonkey | 1 | 24 | 24 | 96G | 100G | Xeon | 2.4 |
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, with the exception of five dblades (dblade66 to dblade70) and tanager which run 32-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 51 "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.
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.
oriole, tanager
Older (Xeon Gallatin, pre-64bit) Intel systems, donated (no strings attached) to the grid by Maurice Herlihy.
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.
