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:
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.
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:
and 40 nodes with the following specifications:
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.
