===== File System =====

ZAMREN uses NFS to serve two directories, HOME and SCRATCH . The HOME directory has a 2.5 GB quota and 
is  backed up. SCRATCH is for temporal storage and is purged periodically and hence not backed up. 
It has a 5TB quota.

==== Home ==== 

When you login,the system automatically sets you to the home directory, /home/xxxxxxxx where xxxxxxxx is replaced by your login name. Users should store important files that should be backed up in this directory up as home directory is backed up daily. This directory has a quota limit of 2.5 GB. The login node and any compute node can access this directory. Users are allowed to install applications in their home directories. However , ZAMREN will not support those applications.

Execution of jobs in the home directory is not allowed. Jobs executed from this directory will be automatically stopped.

==== Scratch ====

The directory is meant for storing temporary files and is accessible from compute nodes. Execution of jobs should be done from here.

Please note that files are not backup up in this directory and can be purged at anytime. No recovery services will be available for files once purged. Users are urged to be saving their files in their home directories.

====Software ====
ZAMREN provides a range of third party and open source software for general use. The following packages are currently installed and supported on the cluster. Users can compile and install their own applications, however, these are not supported.
