== General information on NECluster file-systems ==
All nodes have system drives with the Linux OS installation.
Data directories and NE-specific codes are shared across cluster
from NFS servers via the shared Gigabit network.

== Home directories ==
The home directories are exported from one NFS server.
For this reason the input-output (I/O) performance may suffer
if many users are accessing the same filesystem from multiple nodes.
This can be alleviated by using other shared filesystems for I/O
intensive programs, see below.

User data in are not backed up.
'''Users are responsible for maintaining their own data backups.'''

== Memory mounted /tmp/ directory ==

All nodes have /tmp/ mounted in memory for fast access.
If your job runs on a single node, consider using that for temporary files.
Create your directory /tmp/<username>/

Files are cleared on reboot.

== Shared temporary directory in /home/tmp_scale/ ==

SCALE runs write and read many temporary files. Please use /home/tmp_scale/
filesystem for these files.
This filesystem is exported from a separate NFS server, taking load off your /home/ directory.
Create your own sub-directory /home/tmp_scale/<username>/ and point SCALE there.

Files are deleted from /home/tmp_scale/ after 180 days of last modification.

== Shared scratch directory in /scratch/ ==

Another separate NFS server exports /scratch/ directories.
Please consider using /scratch/ for code development.
Create your own sub-directory /scratch/<username>/

Files are deleted from /scratch/ after 180 days of last modification.
