Pool
In order to get access to the interactive nodes, connect to psananeh if your experiment is in the Near Experimental Hall (NEH) or psanafeh for the Far Experimental Hall, or psanacs for either hall psana:
| No Format |
|---|
ssh psananeh
ssh psanafeh
ssh psanacs
|
A load-balancing mechanism will connect you to the least loaded of the nodes in the pool. The psananeh and psanafeh pools are currently made of 20 servers with the following general specifications:

The psanacs pool is currently made of 32 servers with the following specifications:
- 16-cores, Sandy Bridge E5-2680, 32GB memory, diskless, 1Gb/s
The psananeh and psanafeh pools will be retired by the end of the summer shutdown.
Each node Some nodes in the interactive pools has pool have one single user Matlab license. You can find which nodes in the pool have a Matlab license available by running the following command on any of the psana nodes:

The current Matlab version is 2012a2013a:

Batch Farms
There are a number of batch farms (i.e. collections of compute nodes) located in the NEH and FEH. Instructions describing how to submit jobs can be found on the Submitting Batch Job page. The batch farms currently consist of eighty nodes with the following general specifications:
