I'm Christoph Kluge, main developer of the HPC portal and I will show you the tool or

my tool from the perspective of a user and of a manager or PI.

The main entry point that some of you already know is the login page in which it's required

to log in via SSO, either with the IDM login and the FIU or some other institution of your

affiliation. So it should also work

the other way around. Now I'm logged in.

And the first view you have the user view. And when you log in the first time you will have

the right email subscription box for the first and only time in this view.

Where you can then select the recommended NHRS system announce,

the general NHR users newsletter, and whether you want to subscribe permanently even after your account

or your project has reached its end of validity. I will just update these.

You can change the subscriptions later in your profile which I will show in a short minute.

Give me localization. Yeah, for your user view you have two tabs here. You have your accounts which are

linked to your user and our user HPC Cafe has already one account in the project

Cafe Quality Project. And if you have multiple accounts that will be listed, we will see that later.

You can see your account details, the general ID, your home path, which shell you use, and the state

and your validity date. In this case the state of the home, and the state of the home.

And the state and your validity date. In this case the 30th of January.

This account already has a public SSH key uploaded. I will demonstrate that also in a second.

But just it looks like this if you've already done it. It's a fingerprint, the MD5 fingerprint

of your key, and an alias for yourself to identify the key. These will be used in the cluster

environment for login. This new button directly links your account to Cluster Cockpit.

I will show that also later because I'm on the local page right now. But with a click here you

will be forwarded to Cluster Cockpit, all automatically logged in to your respective account,

and will be shown your jobs in the job list.

This account also obviously has already some computation done in the last year and this year.

So we have some GPU hours, we have some core hours on Flitz, and it's just a listing of the usage done

by this account or your account, which you can also plot for some use back in 2020-2025 at the moment.

Again, this localization hangs a bit. But we have some Flitz hours used up here, and some

Alex as well. Not yet documented, but it's very small bars here because some people calculate in

the 100,000s of hours and on the second cluster they just have a few 100 for testing. You can't

really see these, but you can click on the legend to switch to your data bars as needed.

The second tab is the invitation tab, which is the main path to create accounts in this tool.

In this case, our user HPC Cafe already has one invitation accepted, thus it is archived,

and it was the self-invitation. So a manager can create this or her own account by inviting him or

herself. State accepted, created yesterday. No more new invitations. As a manager or a PI,

you will have a second tab called the management tab where you can view the projects in which you

are either PI or manager. So in this case, we have a fully blown project already here,

the coffee quality project in which our user is the principal investigator. We have not yet

any managers, so it's his own project. PIs are always in charge of the coffee quality, as we know.

Project resources can be viewed in this dropdown. Again, the usage project-wide this month,

this year, and over all the years, and also the quota which is allocated to this project.

You can as well trend this, plot this. It's the same plugin, the same tool, only that this is

summed up over all the accounts of this project. So this is the total GPU hours or total core hours

for this project. Again, I can plot out Alex to better see the small start in Fritz.

On the right side, we have the accounts for this project. So we have the account we just saw

in the user tab. So it's the account of the PI himself. Again, we can view the usages and plot

the usages of this account. We can edit the account, in which case we can change the validity

and view the general information of this account. But you can also view the other accounts. So we

have the demo user, IMS, which also did some computation, far less. So we are on the 100s.
