Login Nodes

Overview of DAIC login nodes and appropriate usage guidelines.

Login nodes act as the gateway to the DAIC cluster. They are intended for lightweight tasks such as job submission, file transfers, and compiling code (on specific nodes). They are not designed for running resource-intensive jobs, which should be submitted to the compute nodes.
