Overview
In 2016, two new HPC clusters were installed at the University Oldenburg in order to replace the previous systems HERO and FLOW. The new HPC clusters are:
- CARL (named after Carl von Ossietzky, of course, but if you like acronyms then try "Carl's Advanced Research Lab") serving as multi-purpose compute cluster
- Lenovo NeXtScale System
- 327 compute nodes
- 7.640 compute code
- 77 TB of main memory (RAM)
- 360TB local storage (HDD and SSD flash adapters)
- 271 TFlop/s theoretical peak performance
- EDDY (named after the swirling of a fluid) used for research in windenergy
- Lenovo NeXtScale System
- 244 compute nodes
- 5.856 compute code
- 21 TB of main memory (RAM)
- 201 TFlop/s theoretical peak performance
Both clusters shared some common infrastructure, namely
- FDR Infiniband interconnect for parallel computations and parallel I/O
- CARL uses a 8:1 blocking network topology
- EDDY uses a fully non-blocking network topology
- Ethernet Network for Management and IPMI
- a GPFS parallel file system with about 900TB net capacity and 17/12 GB/s parallel read/write performance
- additional storage is provided by the central NAS-system of IT services
The systems are housed and maintained by IT services and the adminstration of the clusters is done using the Bright Cluster Manager 7.3.
