You can get into the LCLS photon computing system in the NEH by ssh'ing to one of these nodes:

...

psexport.slac.stanford.edu

...

psimport.slac.stanford.edu

...

From these nodes you can move data files in and out of the system and you can connect to the bastion hosts:

...

pslogin

...

psdev

...

Note that, from within SLAC, you can directly connect to the bastion hosts without going through psimport/psexport.

...

These nodes are reserved for the users who are currently running an experiment. Each instrument has three dedicated interactive compute systems:

...

• AMO:

...

• psanaamo01
psanaamo02
psanaamo03

• SXR:

  psanasxr01
psanasxr02
psanasxr03

• XPP:

  psanaxpp01
psanaxpp02
psanaxpp03

• XCS:

  psanaxcs01
psanaxcs02
psanaxcs03

• CXI:

  psanacxi01
psanacxi02
psanacxi03

• MEC:

  psanamec01
psanamec02
psanamec03

The general specifications for these nodes are:

• psana<instr>01: 8 cores, Xeon E5520, 24GB, 500GB disk, 1Gb/s, dedicated Matlab license
• psana<instr>02: 8 cores, Xeon E5520, 24GB, 500GB disk, 1Gb/s
• psana<instr>03: 8 cores, Opteron 2384, 8GB, diskless, 10Gb/s

Interactive Farm

In order to get access to the interactive farm, ssh to the address psana. A load-balancing mechanism will connect you to the least loaded of the nodes in the farm. This farm is currently made of six 8-cores Opteron 2384 nodes with one 10Gb/s connection to the data.
