Hardware
- 64 SX-ACE nodes with a single vector processor
- 4 cores for 256GFlops peak performance
- 1 GHz frequency
- 16 vectore pipes per core, each doing 2 add and 2 multiply per cycle for a peak performance of 64 GFlops per core
- 1MB ADB (vector cache) per core, enhanced in size, speed and functionality from SX-9
- 64 GB of memory per node
- 32 memory channels for 256GB/s bandwidth, usuable by one core or sharable
- around 260 Watt power consumption per node during Linpack
- nodes are connected through IXS crossbar for message passing with 4GB/s per node
- SUPER-UX Unix based OS
- NQSII batch system
- SX-ACE brochure
- Frontend for Cross Compilation
- Dual socket NEC Express5800/R120e-1M with 2x Intel E5-2697 v2 @ 2.70GHz, running Redhat Linux
- Filesystem
- 250TB NEC ScaTeFS (scalable technology filesystem)
- 2 servers (shared object and metadata servers)
- 4 NEC iStorage M300 raid arrays with 3TB spindles
- Network
- NEC proprietary highspeed network using IXS crossbar for message passing between nodes
- 4GB/s theoretical MPI bandwidth per node
- 40G Juniper QFabric network for 10G ethernet connection of filesystem using QOS to separate metadata and data traffic
