Parallel jobs

  • See QuantumWise's Parallel Guide
  • We use Intel-MPI instead of MPICH2, with the Hydra process manager instead of MPD. See the sample.job file for details:
$ATK_HOME/sample.job


Remote access

To run ATK/VNL directly on your computer (as opposed to running it remotely and sending graphics over the network), follow these steps, all on your computer, to prepare for and launch the application:

Preparation

  • Log out from all Carbon nodes.
  • Log out from Mega.
  • Modify your configuration for SSH port forwarding to Mega. On Mac or Linux, make the changes to your file ~/.ssh/config. On Windows, apply the changes as shown in the help pages of your SSH application.
Add two entries for Remote Forwarding:
Local port: 6200,   Remote Port: 6200@cmgmt3
Local port: 6201,   Remote Port: 6200@cmgmt4
Note that the local ports are different but the remote ports are the same between the two entries.
  • Log back in to Mega. This will activate the tunnel configuration that you added previously, to be used later by the ATK License Configuration wizard.

Download, Install, and Configure

localhost:6201@localhost
  • Finish the helper.

Launching ATK/VNL

  • Log in to Mega if you are not alreay logged in.
    You need to have exactly one Mega session active to access any kind of service on Carbon, be it for a single use or several ones concurrently.
  • Start VNL or atkpython normally for your platform.
