-This is the portal information.
+==== The portal cluster ====
+The ''%%portal%%'' cluster is a general purpose cluster of servers whose logins are load balanced among the servers. Upon an 'ssh' to ''%%portal.cs.virginia.edu%%'', your login will be placed on the least loaded of the cluster's servers (portal[01,02, etc.]). Each system is running CentOS Linux and has plenty of memory, CPU cores, and scratch (/localtmp) space.
+You can use portal to perform many interactive tasks, like editing files, compiling code, testing code, etc. If you intend to run long, compute intensive programs, you should use other [[compute_resources|Computing Resources]] which are available for general login or through the job scheduler (see [[compute_slurm|Scheduling a Job using the SLURM job scheduler]]).
+You must use your CS userid (identical to your UVA userid) and password to 'ssh' to portal. For example:
+''%%ssh -l abc1de portal.cs.virginia.edu%%''. Alternatively,
+''%%ssh abc1de@portal.cs.virginia.edu%%''
+Note that if you are opening a terminal on your Mac or PC, your username on the Mac or PC may be different from your CS domain userid. So be sure to include your CS/UVA userid on the 'ssh' command line.
