 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. The ''​%%portal%%''​ cluster is a general purpose cluster of servers whose logins are load balanced among the servers.

 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 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]]). ​
