The Run Limit refers to the maximum total number of jobs that can be running in a queue. Queue Name refers to the keyword to be used in a PBS job script to access the appropriate queue. Jobs will be accepted in the priority indicated by the last column above. IISER Bhopal students, researchers and faculty members can apply for accounts mentioning the user pool required along with a justification of the resources required. Click on the Application Form To apply online.

The filesystems accessible to the users are divided into two main parts - Home (composing /home1 and /home2) and Scratch (/scratch). All areas are completely backed up on our tape-library (TSM-based).

USAGE POLICY

HOME AREA

Every user will be allocated a home area 1 TB for Core users and 500 GB for Peripheral Users, by default. Additional space can be allocated based on adequate justification. The location of this area will be e.g. /home1/<userid>. and can also be accessed by the environmental variable $HOME

SCRACTH AREA

The Scratch area is mounted on GPFS (parallel-file system) and should be used for I/O intensive activity over the NFS. Every user will be assigned their own directory in the scratch area - e.g. /scratch/<userid>. This is also accessible by the environmental variable $SCRATCH. Currently, there is no quota limit for any user in the scratch area. However, please be advised that files in the scratch area more than 14 days old shall be purged. So users are advised to backup dated files.
