Interactive Pool

In order to get access to the interactive nodes, connect to psana:

ssh psana

The psana pool is currently made of 18 servers with the following specifications:

  • 12-cores, Xeon E5-2620 v3 2.4GHz, 128GB memory, 1 x NVIDIA GPU GTX 1080Ti, 10Gb/s Ethernet, no IB

LCLS provides a few Matlab licenses and one IDL license. Instructions on how to use these tools are in the Matlab and IDL pages.

Each psana interactive nodes has a GPU accelerator.

Batch Queues

There are a number of batch queues (i.e. collections of compute nodes) in the psana systems. Instructions describing how to submit jobs can be found on the Submitting Batch Job page.

The main batch farm currently consist of 80 nodes with the following general specifications:

  • 12 cores, Xeon X5675, 24GB memory, QDR IB

and 40 nodes with the following specifications:

  • 16 cores, Xeon E5-2640 v3, 128GB memory, QDR IB

Remote Visualization

When performing analysis on the psana interactive nodes, it is useful to display plots on your host machine. For host machines near SLAC, using ssh with X-windows forwarding (the -X or -Y options) suffices. X  windows forwarding can get slow for host machines in Europe. Some users have found better performance with technology called nomachine, this is documented on the Remote Visualization page.
