NIH HPC Biowulf Login Node Usage
Date: 28 July 2020 12:07:33
From: NIH HPC Systems Staff
This is a reminder that data transfer and intensive file management
tasks should not be performed on the Biowulf login node, biowulf.nih.gov.
Instead such tasks should be performed on the dedicated interactive
data transfer node (DTN), helix.nih.gov.
Examples of such tasks include:
- cp, mv, rm commands on large numbers of files or directories
- file compression/uncompression (tar, zip, etc.)
- file transfer (sftp, scp, rsync, etc.)
In addition to previously disabled file transfer programs, the sftp
service has been disabled on the login node.
There are typically 200+ users on the Biowulf login node, and this
policy is to ensure the login node remains viable for vital tasks
such as job submission.
Thank you and be safe!
