> 
> The cluster-wide, shared /scratch directory on Biowulf is a low-performance, temporary storage space for users. User jobs on compute nodes that read or write from /scratch (as opposed to the high-performance /data areas) run much slower, impacting both the jobs and the filesystem as a whole. To ensure that user jobs don't access /scratch, and for the stability of the filesystems, /scratch is being removed from the compute nodes.
> 
> /scratch will continue to be accessible from Biowulf, Helix, HPCdrive and Globus.  As before, /scratch can be used for temporary files that are expected to be automatically deleted in 10 days time.
> 
> Any batch or swarm command files which reference the /scratch file system should be modified before Sep 1, to use either your /data directory or /lscratch as appropriate.  Please see https://hpc.nih.gov/storage/index.html for an overview of storage on HPC systems.
