Surface is an unclassified resource for visualization and data analysis work. It is limited access.
Here is a breakdown of the "mixed" composition of CPU/GPU architectures on Surface:
| Architecture | Clock Speed (GHz) | CPUs GPUs |
Cores/CPU Node Cores/GPU Node |
Cores Total | Memory/Node (GB) | Memory Total (GB) | TFLOPS peak |
|---|---|---|---|---|---|---|---|
| Intel 8-core Xeon E5-2670 NVIDIA Tesla K40 GPU |
2.6 745 MHz |
162 158*2 |
16 2880 |
2,592 910,080 |
256 12*2 |
41,472 3,792 |
53.9 451.9 |
The chart, below, is necessarily simplified to the limitations of the database and consistency with other systems.
