qrshx

qrshx is a scheduler command that requests an interactive session on a worker node. The resulting session will support graphical applications. You will usually run this command from a login node.

Examples

Request an interactive X-Windows session that provides the default amount of memory resources and launch the gedit text editor:

[te1st@sharc-login1 ~]$ qrshx
[te1st@sharc-node001 ~]$ gedit

Request an interactive X-Windows session that provides 10 Gigabytes of real memory and launch the latest version of MATLAB:

[te1st@sharc-login1 ~]$ qrshx -l rmem=10G
[te1st@sharc-node001 ~]$ module load apps/matlab
[te1st@sharc-node001 ~]$ matlab

Request an interactive X-Windows session that provides 10 Gigabytes of real memory and 4 CPU cores:

[te1st@sharc-login1 ~]$ qrshx -l rmem=10G -pe openmp 4
