Usage Guidelines
USAGE GUIDELINES
- Users are supposed to submit jobs only through interactive manner
- Users should run and write their jobs from /home/username/foldername only
- Users must understand that HPC is a central facility that is shared by all members of the institute. Users should therefore use an optimum number of processing cores by testing for scaleup.
- Users are strongly encouraged to specify only the required number of processing cores.
- The quota for each user is 50 GB in home directory.
- It is strongly recommended that users backup their files-folders periodically, as ISTF will not be having a mechanism to backup users’ data.
- For any issue or requests pertaining to Aneesur, please send your email with your working-path, error logs and error screenshots and submit-script only at helpdesk.istf@iitgn.ac.in
- Users may use -X as a flag to run X Windows or any GUI based app

External Usage
Computational Resources for External Usage @HPCLab in IITGN
Access to our High Performance Computing (HPC) Facility is granted to external users (Academic/Research organizations and Industry only) through a Committee.
The Proposal from the user should reflect the
- Technical Details of specific facility needed & its duration
- Brief scientific narration of their proposed work
Please send your detailed proposal to support.hpc@iitgn.ac.in
Based on the review outcome and feasibility consideration of our facility, we will allocate computer resources.
Obtaining the HPC Account
- Once the proposal is reviewed, accepted and approved by the committee, the user may download, fillup the HPC application form ink-sign, scan it and email us.
- Thereafter a unique group/user name will be created for the external user and associated user(s) and thereafter the user credentials would be sent in reply-email.
