Directories and filesystems

The INCD filesystems are based on the Lustre shared filesystem which is mounted in the compute nodes and in the submission/login nodes. Lustre is mostly suited to the storage of large/huge files. 

 
 For more specific information regarding the Lustre deployment at INCD please see the lustre section

 [1] Each user belongs to a Unix group: unixgrp - determined by the project they are attached to [2] Increases to these quotas will be considered on a case-by-case basis. [3] Time limit defines time after which a file is erased on the file system since its most recent access time, as defined by the file access timestamp. [4] This folder has read+write permission to all users belong same group 

 

 NOTE: To know your unix group id type the command: id 

 

 Filesystems 

 /home 

 
 Intended to be used for source code, executables and immutable data (input files etc), NOT large data sets. 

 Globally accessible from all nodes within a system. 

 Quotas apply. Please read our Disk Quota Policy To know your actual quota limit: 

 
 lfs quota -uh username /home/unixgrp/username

Disk quotas for usr username (uid XXXXXX):

 Filesystem used quota limit grace files quota limit grace

 /home/unixgrp/username 11.6G 20G 20G - 1395 10400 10400 -

 

 

 NOTE: if your used >=quota users are not allowed to write 

 

 /data 

 
 Each project has a directory with pathname /data/unixgrp on each compute node. Users connected to the project have rwx permissions in that directory and so may create their own files in those areas. 

 Globally accessible from all nodes within a system. 

 Quotas apply. Please read our Disk Quota Policy To know your actual quota limite: 

 
 lfs quota -uh username /data/unixgrp

Disk quotas for usr username (uid XXXXXX):

 Filesystem used quota limit grace files quota limit grace

 /data/unixgrp/ 219.6G 300G 300G - 81395 1102400 102400 -

 

 

 NOTE: There are also limits on the number of files (files) that can be owned by a group (project) on /data. 

 

 /exper-sw 

 
 Intended to be used for software, shared by group 

 Globally accessible from all nodes within a system.
