From YouTube: How to Access a Customer Kernel via Jupyter

Description

How to Setup the Kernel Json File
Neil Mehta (NERSC)

A

So, uh with a with a raise of hands, or rather uh let me uh share my screen and show you: uh how do we access um a custom kernel through Jupiter?

A

A

First of all, using Jupiter on the system is very easy and very simple. All you have to do is visit this particular site. It's called jupiter.nurse.gov. Let me open a new window so that I'm not able to log in and.

A

At any point, if you're unable to follow just uh stop and ask question so that we can immediately resolve this, so when you log in It'll, ask you for a Federated identity, click on it use your nurse credentials, and it should take you to a page like this.

A

I just want everybody uh to try it and if you are able to just raise your hands as a on Zoom.

A

So again the page is jupiter.nest.gov.

A

Okay, good, so once uh you are configured for this, uh the way to log on to Perimeter through an X system would be use your SSH, your username and Paul mutter.

A

A

You should you should be able to see a login page like this.

A

Now many people will not have these directories configured so you'd have to create these directories, but generally look for a directory called CD dot. Local rather CD into this directory called dot local. If you don't have it, you can create this directory using mkdir.local.

A

Inside this, you will have a directory called share.

A

Within this go to a directory called Jupiter again, if you don't have these directories configured at each step, you'll have to make this directory. So if you don't have dot local, please create a directory called M call Dot local in in your home. Follow it up with another directory called share and finally inside share create a directory called Jupiter.

A

Inside the jupyter directory, you will have another directory called kernels.

A

Now, here you can configure any custom kernel that you wish to launch and by this what I mean is let in in this particular exercise. We want to use Q quantum right, so I will create a directory called Q Quantum, which I already have, and let's call it. Cool, Quantum and inside quantum, okay create create a a document. File called kernel.json create sorry, create a Json. What kernel.json.

A

Once you create this, you have to copy the following lines:.

A

I am placing what you have to copy in the kernel: dot Json uh in the zoom chat.

A

So, essentially, what what this allows you to do is use a custom kernel on Jupiter with a shifter image. Shifter a shifter image is built on a cool Quantum Docker container provided by Nvidia NGC.

A

Is everyone clear on this.
