In the calculation of the peak performances we included also the login nodes since they are identical to compute nodes.
The theoretical peak performance is 988*(0,8+4*7,8) = 31,6 PFlop/s
In the below table you can find the single node theoretical peak performance of the AC992 CN node with two Power9 processors and four NVIdia V100 GPUs.
| Node Performance | ||
Theoretical | CPU (nominal/peak freq.) | 691/791 GFlops |
| GPU | 31.2 TFlops | |
| Total | 32 TFlops | |
| Memory Bandwidth (nominal/peak freq.) | 220/300 GB/s | |
Access
All the login nodes have an identical environment and can be reached with SSH (Secure Shell) protocol using the "collective" hostname:
