Introduction
The central HPC facilities of the University of Oldenburg comprise three systems:
- FLOW (Facility for Large-Scale COmputations in Wind Energy Research): IBM iDataPlex cluster solution with 2232 CPU cores (Westmere-EP, 2.66 GHz), 6 TB of (distributed) main memory, and Quad-Data Rate (QDR) InfiniBand interconnect (theoretical peak performance: 24 TFlop/s).
- HERO (High-End Computing Resource Oldenburg): hybrid system composed of two components:
- IBM iDataPlex cluster solution with 1800 CPU cores (Westmere-EP, 2.66 GHz), 4 TB of (distributed) main memory, and Gigabit interconnect (theoretical peak performance: 19.2 TFlop/s),
- SGI Altix UltraViolet shared-memory system ("SMP" component) with 120 CPU cores (Nehalem-EX, "Beckton") and 640 GB of globally addressable memory, and NumaLink5 interconnect (theoretical peak performance: 1.3 TFlop/s).
- GOLEM: older, AMD Opteron-based cluster with 390 cores and 800 GB of (distributed) main memory (theoretical peak performance: ).
FLOW and HERO use a dedicated, shared storage system (high-performance NAS Cluster) with a net capacity of 130 TB.
