Cluster Shell App:  This app provides users with a shell login to access the various cluster front-end servers at CCR.  No need to install a SSH client like PuTTy!




The Academic and Faculty cluster shell options log the user into one of the vortex front-end login nodes.  The Industry cluster shell option logs users into the presto front-end login node.  Academic users have access to all three options; Industry users only have access to the Industry option.  NOTE: The default Slurm cluster on the Industry front-end is 'industry' so academic users will need to specify the option "-M ub-hpc" with all Slurm commands.
