Tegner

Tegner was the pre- and post-processing system for PDC's previous flagship system, Beskow.

Tegner, PDC's pre- and post-processing system

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

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