Accessing the HPDA hardware

The 12 visualization and pre/post processing nodes provide 2048 Gio RAM per node, 2 Slingshot 200 Gb/s NICs and 2 NVIDIA L40 graphics cards. The operating system is RHEL8 and the default CUDA version is 11.2.

The CINES proposes two ways to access the HPDA nodes; via the NiceDCP remote desktop facilities or, through SLURM.

Note

Be well aware that the HPDA nodes possess NVIDIA L40 GPU and the compute nodes possess AMD MI250X GPUs, they work differently.

SLURM reservation

To reserve an HPDA node, simply specify the --constraint= flag to HPDA. For more details on how to reserve a node, you can refer to the Running jobs section.

Remote desktop

Through a web service

Warning

We are waiting internal validation of the visualization software’s web interface. You can already use the HPDA partition through SLURM and X11 forwarding (we know it is suboptimal).
