Hosted at the University of Liège (SEGI), NIC5 consists of 4672 cores across
73 compute nodes, each equipped with two 32-core AMD Epyc Rome 7542 CPUs @ 2.9 GHz.
The default partition contains 70 nodes with 256 GB RAM, while the hmem partition includes
3 nodes with 1 TB RAM, intended for memory-intensive workloads.
All nodes are interconnected through a 100 Gbps HDR InfiniBand fabric
(with a blocking factor of 1.2:1), and have access to a fast 520 TB BeeGFS /scratch space.
Suitable for:
MPI parallel jobs (many communications, dozens of cores),
and SMP/OpenMP parallel jobs.
Max wall time: 2 days.
