Issue to be resolved
Slow Discover jobs due to $TMPDIR I/O performance.
Solution
For jobs that read and write temporary files, there is a fast scratch filesystem using NVMe (flash) technology. Access this storage by using $TSE_TMPDIR where you would currently use $TMPDIR.
Each user has a default allocation of 250 GB and 200,000 inodes. This data is not backed up and is deleted at the end of your job because the resource is very limited. If you have a job that needs more than the default allocation, email support@nccs.nasa.gov so that we can discuss your job requirements.
