-The ''​%%portal%%''​ cluster is a general purpose cluster of four servers whose logins are load balanced among the four 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,​03,04]). Each system is running CentOS Linux 7, has 128GB of memory, ​16 virtual ​cores, and ~200GB of scratch (/localtmp) space. ​The portal ​will eventually replace the old "​power*"​ nodes which are nearing retirement age.+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). 
 + 
 +Most popular software is already available on portal, so you do not need to install it. See: [[linux_environment_modules|Software Modules]]
