A shared scratch area is available in the cluster at /scratch. The size of this are is currently around 3TB. It is shared across all the nodes and hence the data written to this folder (sub-folders included) will be seen (almost) simultaneously from all the other nodes. This space should be used to store TEMPORARY job data ONLY. Please do not store any data that is critical in the scratch space as this is not under any backup / restore schedule. Also, please note that your job needs to handle file writes to this area smartly so jobs do not overwrite each other's input/output/data files.
Currently all files / folders in this scratch area that are older than 60 days are cleaned everyday. So make sure to move your data off this space as soon as your job completes. There is no quota on this area at present, but if need arises, a quota will be imposed later.
