Tegner

Tegner was the pre- and post-processing system for the Beskow system at PDC.

Tegner, a pre- and post-processing system that used to be at PDC

Although Tegner was primarily used as the pre- and post-processing system for Beskow, it was also available as a general cluster for researchers from the Stockholm region or for other users interested in using GPUs.

Tegner was a heterogeneous system which had 67 Supermicro nodes with Intel CPUs - 9 of those nodes had NVIDIA Tesla GPUs. Tegner's memory was quite large with each node having 0.5 TB, 1 TB or 2 TB. In total Tegner had 42.5 TB of main memory. The system was equipped with an EDR Infiniband interconnect.

Usage

  • was primarily used as a pre- and post-processing system for Beskow (Note: A small time allocation on Tegner was automatically included in all Beskow time allocations.)
  • was also available to academic researchers in the Stockholm region for general computational processing
  • was also used in some industrial research projects
