Swing Login Nodes

There are two login nodes available to users for editing code, building code, submitting/monitoring jobs, checking usage (lcrc-sbank), etc. Their full hostnames are and The login nodes hardware is quite different to the compute nodes. The various compilers and libraries are present on the logins, so most users should be able to build their code. However, software requiring GPUs should be built on the compute nodes as the login nodes do not have GPUs installed in them. All users share the same login nodes so please be courteous and respectful of your fellow users. For example, please do not run computationally or IO intensive pre or post-processing on the logins and keep the parallelism of your builds to a reasonable level.
