On the 21st of October 2021 we will be deploying multi-factor authentication on the HPC login nodes (ShARC & Bessemer) for all password logins.
For more information please see our page on this change.
Worker nodes: 26
CPU cores: 1,040
Total memory: 5,184 GiB
Fast network filesystem (Lustre): 460 TiB
Note that some of these resources have been purchased by research groups who have exclusive access to them.
General CPU node specifications¶
25 nodes are publicly available (not exclusive to research groups).
Machine: Dell PowerEdge C6420
CPUs: 2 x Intel Xeon Gold 6138
Skylake processor microarchitecture;
Support for AVX-512 vectorisation instructions (simultaneously apply the same operation to multiple values in hardware);
Support for Fused Multiply-Add instructions (expedites operations involving the accummulation of products e.g. matrix multiplication).
Hyperthreading is disabled on all nodes.
RAM: 192 GB (i.e. 4.8 GiB / core)
Local storage: 1 TiB SATA III HDD
/scratch: 836 GiB of temporary storage;
/tmp: 16 GiB of temporary storage.
GPU node specifications¶
One node is publicly available (not exclusive to research groups):
25 Gigabit Ethernet
Operating System and software¶
OS: Centos 7.x (binary compatible with RedHat Enterprise Linux 7.x) on all nodes
Interactive and batch job scheduling software: Slurm
Many applications, compilers, libraries and parallel processing tools. See Software on Bessemer
Two login nodes (for resilience)
Other nodes to provide:
Lustre parallel filesystem
Slurm scheduler ‘head’ nodes
