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 full configuration includes 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, one to each switch in the pair (redundancy)
- tron[06-44]: Two 50GbE links, one to each switch in the pair (redundancy)
- tron[46-61]: Two 100GbE links, one to each switch in the pair (redundancy)
- 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 (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).
