Zcluster
The Linux cluster is comprised of compute nodes with 4-, 6-, 8-, and 12-core processors from both Intel and AMD. Subsets of nodes have "large memory" (e.g., 128, 256, or 512 GB of RAM), while others have InfiniBand connectivity or GPU capabilities. Total CPU compute power is 25.9 Tflops.
The cluster is currently comprised of the following resources:
- 230 compute nodes (2600 compute cores), 32 with InfiniBand connectivity.
- Four 8-core, 192GB high-memory compute nodes
- Ten 12-core, 256GB high-memory compute nodes
- Two 32-core, 512GB high-memory compute nodes
- Six 32-core, 64GB high-memory compute nodes
- One NVIDIA Tesla S1070 with four GPU cards (4 x 240 = 960 GPU cores) for programs written to use this architecture.
- One NVIDIA Tesla (Fermi) C2075 GPU processor (448 GPU cores)
- Nine NVIDIA Tesla (Fermi) M2070 GPU cards (9 x 448 = 4032 GPU cores). These cards are installed on 2 hosts each of which has dual 6-core Intel Xeon CPUs and 48GB of RAM; there are 6 GPU cards on one host and 3 on the other.
- 32 NVIDIA Tesla (Kepler) K20X GPU cards (32 x 2688 = 86016 GPU cores). These cards are installed on 4 hosts each of which has dual 6-core Intel Xeon CPUs and 96GB of RAM; there are 8 GPU cards per host.
