# Hardware Overview
Karolina consists of 829 computational nodes of which 720 are universal compute nodes (**Cn[001-720]**), 72 are NVIDIA A100 accelerated nodes (**Acn[01-72]**), 1 is a data analytics node (**DAcn1**), and 36 are cloud partitions (**CLn[01-36]**). Each node is a powerful x86-64 computer, equipped with 128/768 cores (64-core AMD EPYC™ 7H12 / 64-core AMD EPYC™ 7763 / 24-core Intel Xeon-SC 8268) and at least 256 GB of RAM.

[User access][5] to Karolina is provided by four login nodes **login[1-4]**. The nodes are interlinked through high speed InfiniBand and Ethernet networks.
