PADUM: Hybrid High Performance Computing Facility at IITD

How to Use and setup the environment.

You will need an ssh client to connect to the cluster through your IITD kerberos credentials. CPU login is available through ssh hpc.iitd.ac.in (Use IITD credentials). To copy data use scp to hpc.iitd.ac.in. GPU or Mic (Xeon Phi) nodes can be directly accessed through gpu.hpc.iitd.ac.in and mic.hpc.iitd.ac.in respectively. Please avoid using gpu and mic for large data transfer.

Once logged in to the system, you have access to your home (backed up) and scratch (not backed up) directories. Please generate an ssh key pair in your .ssh directory to start using PBS. Please report issues to hpchelp[@]iitd.ac.in
