GRNET SA develops and operates the high-performance computing system ARIS (Advanced Research Information System) to support large-scale scientific applications.
Computing Nodes
The ARIS infrastructure comprises of four islands of computing systems in total, based on Intel x86 architecture interconnected into a single Infiniband FDR14 network that offers multiple capabilities and processing architectures.
- An island (thin nodes) is based on the IBM NeXtScale platform and Intel Xeon E5-2680v2 processors. It has 426 computing nodes and offers a total of 8,520 cores (CPU cores).
- An island of nodes consisting of 44 Dell PowerEdge R820 servers. Each server offers 4 Intel Xeon E5-4650v2 processors and 512 GB of central memory.
- An island of GPU accelerator nodes consisting of 44 Dell PowerEdge R730 servers. Each server contains 2 Intel Xeon E5-2660v3 processors, 64 GB of memory and 2 NVidia K40 GPU cards, and
- An island of Xeon Phi accelerator nodes consisting of 18 Dell PowerEdge R730 servers, each containing 2 Intel Xeon E5-2660v3 processors, 64 GB of memory and 2 Intel Xeon Phi 7120P co-processors
