The Tron partition is a subset of resources available in the Nexus. It was purchased using college-level funding for UMIACS and CSD faculty.
Compute Nodes
The partition contains 69 compute nodes with specs as detailed below.
| Nodenames | Type | Quantity | CPU cores per node | Memory per node | GPUs per node |
|---|---|---|---|---|---|
| tron[00-05] | A6000 GPU Node | 6 | 32 | 256GB | 8 |
| tron[06-44] | A4000 GPU Node | 39 | 16 | 128GB | 4 |
| tron[46-61] | A5000 GPU Node | 16 | 48 | 256GB | 8 |
| tron[62-69] | RTX 2080 Ti GPU Node | 8 | 32 | 384GB | 8 |
| tron[00-44,46-69] | Total | 69 | 1840 | 13282GB | 396 |
Network
The network infrastructure supporting the Tron partition consists of:
- One pair of network switches connected to each other via dual 100GbE links for redundancy, serving the following hosts:
- tron[00-05]: Two 100GbE links per node, one to each switch in the pair (redundancy).
- tron[06-44]: Two 50GbE links per node, one to each switch in the pair (redundancy).
- tron[46-61]: One 100GbE link per node. Half of the overall links for this set of nodes go to one switch in the pair, and the other half go to the other switch in the pair.
- One switch connected to the above pair of network switches via two 100GbE links, one to each switch in the pair, serving the following hosts:
- tron[62-69]: Two 10GbE links to the switch per node (increased bandwidth).
The fileserver hosting all Nexus scratch, faculty, project, and dataset allocations also connects to the same pair of switches supporting tron[00-44,46-61] via four 100GbE links, two to each switch in the pair (redundancy and increased bandwidth).
