Info

The jup_sched utility has been deprecated. Please refer to Getting started with HAL OnDemand for instructions to use Jupyter Notebook with HAL OnDemand


Warning
titleDo not run Jupyter directly on the login node

You will not get GPUs this way and will also impact others' ability to use the system. Refer to the link above.
