Shared directory

A shared directory (/ist/ist-share/LABS) that all users allow to create and store their files for each laboratory.

Local Scratch

A scratch directory is a temporay directory in each node that can use to read/write files (/scratch). Scratch is a shared directory for all users but each file will be deleted in 60 days start from created time.

This directory can be access by Slurm job only. We recommended to write a command to transfer the result back in job script.
