Users, projects and accounts at NSC - FAQ

If you are a new user who have not used NSC systems before, read the Getting started section below.

If you are the Principal Investigator (PI) for a project and want to know about how to manage it (add new members etc), read the Managing my project section below.

If you want to apply for a new project, read the NSC Apply for time page

Getting started as a new user at NSC academic systems

In this section we try to answer the most common questions about how to get started using NSC resources, i.e how you get to the point where you can login to one of our systems. Information on how to use NSC systems (e.g run batch jobs) can be found in the User Guides.

Note: this section applies to NSC:s academic systems (as of 2013-03-14: Kappa, Matter, Triolith).

For other systems (e.g SMHI resources, Vagn or our grid systems) there might be other routines to follow. If you need access to these systems and are unsure of what to do, please contact NSC Support

What is NSC Express?
NSC Express is our user portal. You can use it to register as a new NSC user, to change your contact information, to request membership in projects, subscribe to our newsletter and more. NSC Express replaces most of the paper forms used earlier.
What is SUPR?
SUPR - SNIC User and Project Repository can be loosely defined as a user portal/NSC Express for all SNIC centers. You can use it to apply for new Medium and Large projects on any SNIC resource, and apply for membership in Medium and Large projects that were created after June 3rd, 2013. Please see FIXME! for more information on how to use SUPR.
Why both SUPR and NSC Express?
Eventually, SUPR will take over most of the functions now handled in NSC Express (and other local systems at the other SNIC centres). During the transition, some things will appear to become more complicated, but remember that the overall goal is a single SNIC system (SUPR) where you can handle all your user/project management needs, and when we get there we believe that all users will benefit from the new system. All new Medium and Large projects created after June 3rd, 2013 are managed from SUPR. E.g if you want to apply for membership in a new SNAC large project that starts July 1st 2013, you should do so in SUPR. If you try to manage such a project in NSC Express, you will be redirected to SUPR.
How can I access NSC Express?
To login to NSC Express you use the email address you have registered in NSC Express and your NSC Express password. Note: Your NSC Express password is not used for anything else and you cannot use e.g your Triolith password to login to NSC Express.
How do I get an NSC Express password?
If you have used an NSC system (computing resource/cluster/supercomputer/etc) or received our newsletter NSC News before, you are probably already registered in our database. In that case, do not register a new user in NSC Express. Instead, click here and follow the instructions. You will be asked to prove your identity either by logging into an NSC system (e.g Triolith) and run a certain command there or by contacting NSC Support via email.
How do I register in NSC Express if I have never used NSC systems?
If you have never used an NSC system or received our newsletter NSC News, you need to register as a new user in NSC Express. Please click here and follow the instructions to create a new user in NSC Express.
What happens when I register as a new user in NSC Express?
You will be asked to fill out a form with some personal information. Once you submit that, an activation email will be sent to you to confirm that your email address is working. Once you have clicked on the link in that email, you can use NSC Express. When you enter NSC Express for the first time, you will be asked to print out the NSC User Agreement, sign it and send it to NSC together with other neccessary documents (e.g passport copy). Once NSC receives and approves your signed User Agreement and other documents, we can give you access to our systems (e.g HPC clusters). However, we will not create a login account for you before you are a member of an active project.
What is an NSC system?
An NSC system can be an HPC cluster, a storage system or some other computing resource. NSC users typically have access to one or more systems. The term "resource" is sometimes used to describe a system. Examples of NSC systems: Triolith, Kappa, Matter.
What is a login account?
To access an NSC system you need a login account on that system. Having a login account on a system does not automatically entitle you to access other systems (e.g if you have an account on Triolith, you can not use it to login to Kappa). Most users will have the same username (e.g x_abcde) on all NSC systems, but they will use a different password for each account. Example of login account: x_makro on Triolith.
Who can get a login account on NSC systems?
For most systems (e.g all SNIC HPC clusters, Matter, the LiU part of Kappa etc), you need to be a member of a project that has been allocated computing time on that system to get a login account. You also need to be registered in NSC Express and NSC must have received and approved your signed User Agreement.
How do I get a login account on an NSC system?
Login to NSC Express. You can either request the login account when applying for membership in a new project, or at any time after that using the "Manage My Accounts" button. When you request a login account, we will create that account as soon as two requirements are met: you must be a member of a project with allocated computing time on that system, and we must have recevied your signed User Agreement and passport copies. If those requirements are met, you will normally get your login account within one working day of your request. When your login account is created, the login details will be sent to the email address you have registered with NSC Express. Note: after receiving the email, you need to login and set a permanent password within 7 days, or the account will be locked.
What is a project at NSC?
Resources (usually computing time) on NSC systems are always allocated to projects, not to individual users. A project always has one Principal Investigator (PI) who "owns" the project. The PI of a project decides who gets to use the computing time that has been allocated to the project (e.g approves new members). A project can have computing time allocations on more than one system (e.g 10000 core-hours/month on Kappa as well as 50000 core-hours/month on Triolith). All allocations are time-limited (e.g 5000 core-hours/month on Triolith between 2011-01-01 and 2011-06-30). A project can have any number of members. Projects can have quite different names depending on their type (e.g "SNIC 012/28-9", "matter18", "LiU-2011-00228-5"). Since some systems do not accept project names with spaces, uppercase letters etc in them, whenever you use a project name on a system (e.g to submit a batch job), you should use the "Resource Manager Name" for the project. This name is listed on the project page in NSC Express. Example: "SNIC 012/28-9" has the Resource Manager name "snic-012-28-9".
How do I become a member of a project?
If the project is a LiU local project, a SNAC Small Scale project or a Matter projects, apply through NSC Express (see below). If the project is a SNAC Medium or Large Scale project created before June 3rd, 2013, use NSC Express. If not, use SUPR to apply for membership
How do I become a member of a project managed from NSC Express?
Login to NSC Express. Click "Manage my projects". Search for the project you want to become a member of using the name or the title of the project or the Principal Investigator's name. Click Request to request membership. An email will then be sent to the Principal Investigator (PI) who can approve or deny your request. Regardless of what the PI decides, you will get an email telling you the decision. If your request is approved, you can use that project for jobs on NSC systems within one hour. If you do not have login accounts on all the systems that the project has been allocated computing time on, you will be given a choice to request those accounts when applying for project membership.
How do I apply for my own project?
Read the NSC "Apply for time" page
How can run VASP at NSC?
Due to license restrictions, NSC is only allowed to give access to our VASP binaries to users that are already covered by a VASP license. There are three ways to get access to our VASP binaries:

  • You can be added to one of the licenses that we have on file by referring us to the license number that you are covered by. We will then confirm this with the holder of that license.
  • If we don't have the license that you are covered by on file, then you must provide a photocopy of the license agreement and the license number. This number is printed on the invoice, so people generally send us a photocopy of the invoice as well.
  • If you know that you are covered by a license, but we don't have it on file and you don't have access to the license contract, then we can confirm that you are a registered user with the VASP developers. This will usually take a couple of days since we have to email the VASP developers and get a reply from them.
If you have a VASP license but cannot run our VASP binaries, contact NSC Support and provide us with the information needed (e.g VASP license number).

Managing my project using NSC Express

What is a project at NSC?
Resources (usually computing time) on NSC systems are allocated to projects, not to individual users. A project always has one Principal Investigator (PI) who "owns" the project. The PI of a project decides who gets to use the computing time that has been allocated to the project (e.g approves new members).
What is NSC Express?
NSC Express is our user and project portal. As a Principal Investigator (PI) for a project, you can use it to manage your project (add members, remove members, approve membership requests, etc). You can also apply for certain types of projects (SNIC Small Scale and LiU projects) from here. NSC Express replaces most of the paper forms used for user and project management.
Which projects can be managed from NSC Express?
From NSC Express you can manage LiU local projects, Matter projects, SNAC Small Scale projects, and SNAC Medium/Large projects created before June 3rd, 2013.

For SNAC Medium/Large projects created after June 3rd, 2013, use SUPR.

I got an email from NSC Express with a project membership request. What do I do?
Users can use NSC Express to request membership in your project. When this happens, you will receive an email telling you that someone has requested membership in your project. This email contains a link to a webpage where you can approve or deny the request. If you approve the request, the user will be added to your project, and no further action from you is required - the user can immediately start using your project.

Note: you do not need to login to NSC Express to approve a membership application - the email you receive contain a one-time link that enables you to approve the request without an NSC Express password. All you need is access to your email and a web browser.

How can I access NSC Express?
To login to NSC Express you use the email address you have registered in NSC Express and your NSC Express password. Note: Your NSC Express password is not used for anything else and you cannot use e.g your Triolith password to login to NSC Express.
How do I get an NSC Express password?
If you have used an NSC system (computing resource/cluster/supercomputer/etc) or received our newsletter NSC News before, you are probably already registered in our database. In that case, do not register a new user in NSC Express. Instead, click here and follow the instructions. You will be asked to prove your identity either by logging into an NSC system (e.g Triolith) and run a certain command there or by contacting NSC Support via email.
How do I create accounts at NSC for new members in my project?
If you need to add users to your project that has not used NSC systems before, you should ask them to register as new users in NSC Express. When they have registered in NSC Express, they should apply for membership in your project (e.g SNIC 004/71-1) and for an account on the systems (e.g Kappa) that they will be using. This is described in the Getting started section of this FAQ.
How do I add new members to my project?
There are two ways to add a member to a project:
  • You can add users using NSC Express. Login to NSC Express and click the Manage My Projects button. You can then add and remove members (but only users that are already registered in NSC Express)
  • Users can use NSC Express to request membership in your project. When that happens, you will receive an email telling you that someone has requested membership in your project. This email contains a link to a webpage where you can approve or deny the request. If you approve the request, the user will be added to your project, and no further action from you is required - the user can immediately start using your project.
How do I remove members from my project?
You can remove users using NSC Express. Login to NSC Express click the Manage My Projects button. Click on the project you like to remove members from. You can then remove or add members (but you can only add users that are already registered in NSC Express).
How can I see how much computing time has been used in my projects?
Login to NSC Express. Click "Job Accounting" in the left-hand menu. The initial display will show a summary of all jobs run by you in all projects on all NSC systems. You can then change the settings and click "Update Report" to view other types of reports.
