Head node

  • The head node is wonko.bi.up.ac.za

Compute servers

  • There are 10 x 28-core compute nodes with 128 GB RAM each (wonko1 - wonko10). These nodes constitute the short, normal and long queues.
  • There is a 96-core SMP server with 3 TB of RAM (alf). This large multicore server takes care of the bigmem queue on its own.

Storage

  • Please also see Storage Quotas and Charges
  • Home directories are on a 70 TB NFS4 filesystem over Infiniband (/home)
  • User data directories are on a 1.2 PB Lustre filesystem over Infiniband (/nlustre/users)
