Shifter image of STAR SL13a


A demonstrator STAR Shifter image is available for testing at Edison.

 At this time there is only one STAR image available for starver=SL13a. To deploy it on a single 32 core Cori node for 30 minutes execute the following sequence of commands (marked in bold

 /* login to Edison, keep graphics port open */

my-laptop$ ssh -A -X

/* load needed module */
edison06:~>$ module load shifter


/* verify you see STAR shifter image */

edison06:~> shifterimg images | grep balewski

/* request one interactive node with 32 cores for 30 minutes */
