-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: You must use your CS userid (identical to your UVA userid) and password to '​ssh'​ to portal. For example:
