Architecture

The NEC Cluster platform (vulcan) consists of several frontend nodes for interactive access (for access details see Access) and several compute nodes of different types for execution of parallel programs. Some parts of the compute nodes comes from the old NEC Cluster laki.

Compute node types installed:

• Haswell, Skylake, CascadeLake
• different Memory nodes (128GB, 256GB, 384GB)
• Pre-Postprocessing node with very large memory (1.5TB)
• Visualisation/GPU nodes with AMD Radeon Pro WX8200, Nvidia Quadro RTX4000 or Nvidia Tesla P100
• KI nodes with Nvidia Tesla V100
• Vector nodes with NEC Aurora TSUBASA CPUs

Features

• Operating System: Centos 7
• Batchsystem: PBSPro
• node-node interconnect: Infiniband + GigE
• Global Disk 2.2 PB (lustre) for vulcan + 500TB (lustre) for vulcan2
• Many Software Packages for Development
