ClustersKarolina NG
Hardware Overview
Work In Progress
Karolina NG is still WIP and subject to change.
Karolina NG consists of 20 accelerated nodes (Acn[01-20]). Each node contains 2x AMD EPYC™ 9555, 64-core, 3.2GHz (4.4GHz boost) processors and 1520GB DDR5 RDIMM.
User access to Karolina NG is provided by two login nodes login[1-2]. The nodes are interlinked through high speed InfiniBand and Ethernet networks.
For more technical information, see the Compute Nodes section.
