We have 2 Lenovo ThinkSystem SR650 nodes for high memory jobs. These nodes should only be used for jobs which utilise at least 128GB RAM, but ideally more than 512GB RAM.
Accessing the high memory nodes
These nodes have been restricted to only allow jobs which pass the
-l highmem option in the job script.
|SRM||Lenovo ThinkSystem SR650|
|Processor||2 x 18 Core Intel Xeon Gold 6150 (Skylake)|
- srm nodes have a large local temporary folder space. Using
tmpdir rather than central storage can result in
considerable performance improvements. Additionally there is a smaller 1.6TB
/fastwhich uses NVME devices, and should give around double the performance of local SSD storage. However, unlike tmpdir, it will not clean itself and you will need to ensure your files are cleaned up at the end of the job.
- Access is permitted upon request for QMUL researchers who have memory requirements that exceed the existing high memory nodes Please raise a ticket by emailing email@example.com with an overview of requirements.
