Overview of High Performance Computing (HPC) environments @ UMCG/RUG

Key features of the current 2.x High Performance Computing (HPC) environments @ UMCG/RUG::

• Job scheduling: ​SLURM
• Account management: multiple account servers with centralized account management via IDVault. Hence you have the same account for different clusters.
• Linux OS: CentOS 6.x
• Distributed over multiple data centers.

Server overview

Server types

Server types that you can access directly:

• User Interface (UI) servers: this is where you login to manage your jobs
  • Thin UIs: Small virtual machines with a just a few cores, little memory, etc. Only suitable for job management; not for running/testing large interactive scripts/commands.
  • Fat UIs: Large physical machines with many cores, lots of memory and sometimes local fast scratch disks. Can be used for both job management and for running/testing large interactive scripts/commands.
• Data Staging servers: Dedicated machines for large data transfers.

Server types that you can access indirectly:

• Schedulers: Determine which jobs will be executed on which nodes and when.
• Nodes: Crunch jobs submitted to queues/partitions.
