+==== 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 computing resources in the Dept.
+See [[linux_ssh_access|Linux Server Access]] for information about accessing CS Dept servers.
-You must use your CS domain userid (identical to your UVA userid) and password to 'ssh' to portal. For example:
