High Performance Computers  (KDM)

The Computing Services Department is responsible for the maintenance and expansion of KDM. The computing resources of the Center are interconnected by the WCSS internal network and connected to the Wrocław Academic Computer Network (WASK). 

In June 2021, the Center launched its Bem 2 cluster, the latest computing machine with the following parameters: 

• access node for local users of KDM WCSS: ui.wcss.pl
• computing power: 2,2 PFLOPS
• operating system: Alma Linux
• microarchitecture: Cascade Lake
• CPU cores: 24 288
• RAM: 141 TB
• temporary space: 750 TB Lustre
• 506 computing nodes:
  •  277 HUAWEI CH121L V5 nodes consisting of:
    • CPU: 2 x Intel Xeon Platinum 8268 (24 cores, 2,9 GHz)
    • RAM: 192 GB 2933 MHz ECC DDR4
    • network card: Infiniband EDR 100 Gbps
  • 229 węzłów HUAWEI CH121L V5 consisting of:
    • CPU: 2 x Intel Xeon Platinum 8268 (24 cores, 2,9 GHz)
    • RAM: 384 GB 2933 MHz ECC DDR4
    • network card: Infiniband EDR 100 Gbps

• computing network: Interconnect Infiniband EDR, capacity up to 100 Gbps, ultra-low delay (on the order of microseconds)
• software available on the Bem 2 cluster.

The scientific software used on the clusters includes: Amber, Matlab, system kolejkowy SLURM Workload Manager. The KDM team supports researchers in preparing and launching computing operations, compiling software and optimizing applications.

The WCSS computers can be used free of charge, on the basis of the so-called computing grants. Grant applications are accepted continuously.
