Research Computing has several node types available on our resources. Each node type is meant for certain tasks. These node types are relatively common for other HPC centers. We will discuss each node type and its intended use below.
- Four virtual machines
- This is where you are when you log in
- Do not use for: computation, compiling code, interactive jobs, or long running processes
- Use for: editing scripts, moving files, scheduling jobs
Policy for use of login nodes:¶
The RC login nodes are lightweight virtual machines that serve as gateways to CURC computing resources including Blanca, Summit and Alpine. They are strictly intended for non-computational tasks including editing scripts, moving files, scheduling jobs to run on CURC computing resources, and non-intensive workflow monitoring/management tasks. They are not intended for computational tasks of any kind. CURC personnel regularly monitor processes on the login nodes and reserve the right to terminate processes in violation of this policy without notice. Repeated violations by the same user may result in a suspended account.
- Where you compile code, such as Fortran, C, C++
- No heavy computation
- Submit Jobs
- Access these nodes by typing
ssh scompilefrom a login node
