New Clusters in MetaCentrum: Infrastructure Expansion with CESNET and CERIT-SC Resources

We are pleased to announce the successful integration of new computing clusters owned by CESNET and CERIT-SC into the MetaCentrum infrastructure. This expansion brings increased capacity for both CPU and GPU calculations.

Below are the technical specifications of the new machines.

1. Cluster hildor (CESNET)

Owner: CESNET (hildor[1-20].metacentrum.cz, deimos[1-13].meta.zcu.cz, haldan[1-15].metacentrum.cz), České Budějovice, Plzeň, Brno
Capacity: 48 nodes / 6 144 CPU cores
Node configuration:

CPU: 2x AMD EPYC 9555 (64 cores per node)
RAM: 768 GiB
Home: 2x 1,92 TB NVMe
Net: 10 nebo 25 Gbit/s + Infiniband HDR200
Node performance: SPECrate 2017_fp_base 1700

The clusters are intended for computationally intensive tasks utilizing CPUs, and do not include GPU acceleration.

2. Cluster grogu (CERIT-SC)

Owner: CERIT-SC (grogu[1-3].cerit-sc.cz, grogu[4-8].cerit-sc.cz), Brno
Capacity: 8 nodes / 768 CPU cores / 12 GPUs
Node configuration:

CPU: 2x AMD EPYC 9454 48-Core Processor (96 cores per node)
GPU: 4x NVIDIA RTX PRO 6000 Blackwell Server Edition (grogu[1-3])
RAM: 1536 GiB
Home: 6x 7 TB NVMe
Net: 100 Gbit/s
Node performance: SPECrate 2017_fp_base 445

The clusters are intended for computationally intensive tasks utilizing CPUs, nodes grogu[1-3]include 4x GPU accelerators.
