Tips for the cluster

Expanding upon the coding tips page provided by Lucas Estrada.

If a user’s name was John Harvard:

unix/ bash

• rsync: move files from local drive to remote
• find . -exec touch {} \;: touch all files within a directory
• scp source_filepath/filename jharvard@login.rc.fas.harvard.edu:destination:filepath: from your local machine, moves a file onto the cluster. Use the recursive flag to move multiple files, reverse the order of the arguments to move files from the cluster to your home machine.

slurm

• salloc: starts an interactive job
• sshare: prints fairshare score

slurm flags

• -p controls partition (eg. huce_cascade, huce_intel)
• -c controls cpus per task
• -m minimum memory per core
• -d controls dependencies
• -r makes the argument recursive
