We have 4 NeXtScale nx360 M5 nodes on Apocrita with Nvidia Tesla K80 GPU cards.
|Processor||2 x 16 Core Intel Xeon E5-2683V3 (Broadwell)|
|Interconnect||Mellanox ConnectX-4 EDR Infiniband|
|GPU||Tesla K80 with 2 x GK210 chip|
|CUDA cores||2496 per chip|
|GPU Memory||12GiB per chip|
Accessing the nxg nodes¶
Access is permitted to QMUL researchers upon request. Note that access to GPU nodes is not permitted for Undergraduate and MSc students. Please raise a support ticket by emailing email@example.com with a brief overview of intended use, so that we can verify that the jobs will use the GPUs correctly. More detail is on the using GPUs section.
Please ensure that you specify system (as opposed to GPU) RAM carefully when
requesting a "half-node job" (i.e. to make use of a single GPU).
Remember that CPU memory is per core, so if you are using 1 GPU and 16 CPU
-l h_vmem=7.5G will request 120GB of system RAM.
