Feature(s)


Description

THE SYSTEM HAS BEEN DECOMISIONED IN FEBRUARY 2026 AFTER ALMOST 10 YEARS OF SUCCESSFUL OPERATION.

The RRZE’s Meggie cluster (manufacturer: Megware) is a high-performance compute resource with high speed interconnect. It is intended for distributed-memory (MPI) or hybrid parallel programs with medium to high communication requirements.
  • 728 compute nodes, each with two Intel Xeon E5-2630v4 „Broadwell“ chips (10 cores per chip) running at 2.2 GHz with 25 MB Shared Cache per chip and 64 GB of RAM.
  • 2 front end nodes with the same CPUs as the compute nodes but 128 GB of RAM.
  • Lustre-based parallel filesystem with a capacity of almost 1 PB and an aggregated parallel I/O bandwidth of > 9000 MB/s.
  • Intel OmniPath interconnect with up to 100 GBit/s bandwidth per link and direction.
  • Measured LINPACK performance of ~481 TFlop/s.
Meggie is a system that is designed for running parallel programs using significantly more than one node.
