Unit: Faculty of Physics

Keywords: Supercomputer, cluster BullX 500

Responsible person: Dr. Mindaugas Mačernis, +370 5 236 6049

85 computing nodes.

85 computing nodes (24 computing cores per node with SSE4.2 processor instructions, 95 GB of RAM); expected physical availability of computing nodes: 50%.

Nodes are connected by an IB network with a speed of 40 Gbps with other nodes of the cluster and clusters.

The entire system uses high-performance file systems: 46TB (100 Gbps speed in the IB network) and 289 TB (40 Gbps speed in the IB network). The maximum file size for the task is 200TB.

Task queues: SLURM
Operating System: Red Hat Enterprise Linux release 8.4

Architecture: BullX.

Applicability

OpenMP and MPI type
calculations by selecting the number of nodes, cores, and memory required for the task in the Linux RHEL8 environment.
