- 177 thin nodes, each with 32 Broadwell cores, 64 GB RAM
- 32 fat nodes, each with 32 Sandy Bridge cores, 2.7 GHz, 256 GB RAM
- 64 GPGPU nodes each with dual NVIDIA Tesla K40m GPUs, 96 GB RAM
- 18 KNL nodes, each with 64 Knights Landing cores, 96 GB RAM
All nodes are connected with FDR 56 Gbps infiniband, and they are attached to 7.9 Pbyte of online storage.
Furthermore, SURFsara provides:
- Lisa, the national compute cluster, offering 7856 CPU cores
- an HPC Cloud, allowing researchers to buid their own high-performance compute infrastructure;
