Scratch file system purpose is for temporary user data storage. Users data, either intermediate or final, that are spawned on execution time, must be placed on scratch. Users are forced to make use of this temporary space, avoiding thus to exceed their quota limits on their home directories. For each user there is a unique folder in scratch named with the corresponding username. Thus, users must format their scripts so as for the spawned data to be saved on scratch.
Attention: Quota limits are also activated in the scratch filesystem, thus users cannot exceed the limit that has been allocated to them. Also, data older than one month are automatically deleted, thus users should take of their data properly. Scratch filesystem should not be taken for granted as a permanent storage solution.
