We are pleased to announce the successful integration of new computing clusters owned by CESNET and the University of West Bohemia (ZČU) into the MetaCentrum infrastructure. This expansion brings increased capacity for both CPU and GPU calculations, as well as a specialized SMP node with large shared memory.
Below are the technical specifications of the new machines.
This cluster replaces the original cluster of the same name. It is designed for demanding CPU calculations and does not contain graphics accelerators. The cluster is already available in standard scheduler queues.
Owner: CESNET
Adress: adan[1-48].grid.cesnet.cz
Total capacity: 48 nodes / 6 144 CPU cores
Node configuration:
CPU: 2x AMD EPYC 9554 64-Core Processor
RAM: 768 GiB
Disk: 2x 3.84 TB NVMe
Net: 25 Gbit/s
Node performance: SPECrate 2017_fp_base: 1360
The alfrid[1-9].meta.zcu.cz cluster underwent significant modernization and expansion in two phases (May and December 2025). It replaces the original hardware and now offers 8 GPU nodes and one SMP node.
a. GPU nodes (alfrid (4 nodes) a alfrid-II (4nodes)) These nodes are equipped with NVIDIA L40 and L40S accelerators, suitable for accelerated calculations and AI tasks.
Owner: ZČU Plzeň
Total capacity: 8 nodes / 1 024 CPU cores
Node configuration:
CPU: 2x AMD EPYC 9554 64-Core Processor
RAM: 1 536 GiB (alfrid) / 768 GiB (alfrid-II)
GPU: 2x NVIDIA L40 48GB (alfrid) / 4x NVIDIA L40S 48GB (alfrid-II)
Disk: 2x 7 TB NVMe
Net: 25 Gbit/s
Node performance: SPECrate 2017_fp_base: 1230
b. SMP node (alfrid-smp) A specialized node designed for tasks requiring a large amount of shared memory.
Owner: ZČU Plzeň
Adress: alfrid-smp.meta.zcu.cz
Capacity: 1 uzel / 128 jader CPU
Node configuration:
CPU: 2x AMD EPYC 9554 64-Core Processor
AM: 4 608 GiB (přibližně 4,5 TB)
Disk: 2x 7 TB NVMe
Net: 10 Gbit/s
Node performance: SPECrate 2017_fp_base: 1200
