Raijin Fujitsu Primergy - System Details
Raijin is a high-performance distributed-memory cluster is based on Intel Sandy Bridge 8-core processors (2.6 GHz)
- 57,472 cores in the compute nodes;
- Approximately 160 TBytes of main memory;
- Infiniband FDR interconnect; and
- Approximately 10 PBytes of usable fast filesystem (for short-term scratch space).
- Peak performance of approximately 1.2 PFlops -- 8.6 times that of the previous peak system;
- Sustained performance of approximately 6.7 times the previous peak system (i.e., an aggregate SPECfp_rate2006 of 1.6M); and
- Filesystem performance which is approximately 6 times that of the previous system; and consistent with NCI's requirements that the system be well-balanced.
- Two-thirds of the nodes have 32 GBytes, i.e., 2 GBytes/core;
- Almost one-third of the nodes have 64 GBytes, i.e., 4 GBytes/core; while
- Two (2) per cent of the nodes have 128 GBytes, i.e., 8 GBytes.core.
The System software includes:
- CentOS 6.4 Linux distribution (based on RHEL6.4)
- the oneSIS cluster software management system
- the Lustre cluster file system
- Altair PBSpro batch management system, with customised hooks for NCI requirements
