Getting access for externals

Kurzinformation

While getting access to the RWTH Compute Cluster is easy for RWTH members and for members of the Research Centre Jülich (FZJ) in the context of Jülich Aachen Research Alliance (JARA), it is more complicated for external scientists.

In order to use the RWTH Compute Cluster you need

  1. to register in the RWTH Identity Management System (IDM)  in order to receive your username (ab123456) and then
  2. receive your personal HPC user account.

RWTH members, students and employees, are already registered and have their username (ab123456), with which they can provide their personal HPC account by using the SelfService capabilities of the RWTH Identity Management System, see https://rwth-aachen.de/selfservice

Members of Research Centre Jülich can use the Identity Provider of FZJ, see Coupon Procedure to receive their TIM-Id and then provide their personal HPC account by using the SelfService capabilities of the RWTH Identity Management System, see https://rwth-aachen.de/selfservice.


 Detailinformation

Getting Access to the RWTH Compute Cluster

 

External scientists can get access to the RWTH Compute Cluster only in the context of a computing project that has to be approved by technical and scientific reviewers.

External scientists from any German research institution can write an application, identified by an automatically generated unique application-id, and once reviewers have approved this application, a project-id is assigned and a HPC project account is generated.

Alternatively, principle investigators can invite externals, also from other countries - as long as the German Federal Office for Economic Affairs and Export Control (BAFA) has no objection, to participate in an approved computing project as project members.

In both cases, externals will receive their username (ab123456) and their HPC user account as part of a related coupon process.

 

In the following, the application process is described in details:

The applicant, the computing project’s principle investigator and/or his/her contact person, initially is identified by his/her unique email-address.
Whenever the applicant accesses the JARDS online application system the identity of the applicant is first checked by an email callback method.

After navigating through the link sent by email the applicant can then (continue to) fill out the online application forms and upload a project description.

After finalization of the application, JARDS sends the filled out application forms to the applicant as one pdf file.

The applicant has to read, check, and sign a printed version of this pdf file and send it to the IT Center’s ServiceDesk.

Once the IT Center receives this paper version, it creates a case in the electronic ticket system, which sends an email with the ticket number “[#yyyymmdd-nnnn]” as part of the subject line to the applicant.  This ticket is used to keep track of the whole application procedure.

The technical reviewer checks the application and contacts the applicant if there is any formal or technical question. The technical reviewing process typically takes about one week.

The IT Center’s system administrators need to know the username (ab123456) of the applicant before they can generate a HPC project account.  Applicants who already have a username (ab123456) had to provide their id as one of the application form entries.

  • For external applicants JARDS initiates an additional process to provide such a username (ab123456) and the corresponding HPC account. For security reasons, this process is a little complicated.
  • JARDS sends an email to the applicant including a one-time web link, which the applicant has to visit and accept the RWTH Compute Cluster’s terms of use.
  • After acceptance of these terms of use, another email is sent to the applicant containing a coupon code and another one-time web link.
  • The applicant visits this web site, enters his coupon code to generate his unique username (ab123456) and adds his email address.
  • He receives another email with a one-time web link to verify that this email address is connected to his TIM-id.
  • The applicant visits this one time web page, enters his first and last name and receives his username (ab123456) and his password.
  • Again, the applicant receives an email from IDM including a one-time web link.
  • On this one time web page the applicant has to confirm that the JARDS-coupon code has to be connected to his username (ab123456).
  • The HPC account, which corresponds to the applicant’s TIM-id, is then generated automatically.
  • Finally, the applicant’s email address is added to the RWTH Compute Cluster’s mailing list (rzcluster@list.rwth-aachen.de) which is used to distribute important information concerning the cluster’s operation.
  • Using the selfservice online portal the applicant still has to define the password for his HPC account.
  • The connection of the PI’s / PC’s unique username (ab123456) to the coupon code is essential for later adding additional external project members to the HPC project account.

Once all technical questions are resolved, the project-id is determined and the HPC project account is generated and connected to the applicants personal HPC account (unless the application is for a follow-up computing project and the previous project-id can remain). An initial small (test) quota is set and an email is sent to the applicant.

Further actions that the manager (PI / PC) of a HPC project has to take are described in here . Work can then start using the computer cluster consuming the initial test quota.

Once the scientific reviewers approve the application this quota will be increased to the amount that is determinate by the reviewers. The scientific reviewing process roughly takes one month.

 

Adding an external scientist to an existing computing project

 A PI/PC who is a RWTH member can use the RWTH IdM partner mechanism to register additional external project members. The PI / PC acts as a sponsor for the external partner and is responsible for this partner.

Using the RWTH Partner Manager online portal at http://www.rwth-aachen.de/partner-manager, the PI / PC generates a coupon code which the external partner can use to get a RWTH TIM-Id.

An external PI/PC does not have the privilege to act as a sponsor. He can use the cluster-access web portal at https://www.jards.itc.rwth-aachen.de/cluster-access/ to invite and register additional external project members.

  • The invitee receives the email sent by the cluster-access web portal including a one-time web link, which the he has to visit and accept the RWTH Compute Cluster’s terms of use.
  • After acceptance of these terms of us, another email is sent to the external project member containing a coupon code and another one-time web link.
  • The invitee visits this web site, enters his coupon code to generate his unique username (ab123456) and adds his email address.
  • He receives another email with a one-time web link to verify that this email address is connected to his TIM-id.
  • The invitee visits this one time web page, enters his first and last name and receives his TIM-id and his TIM password.
  • Again, the invitee receives an email from IDM including a one-time web link.
  • On this one time web page the external project member has to confirm that the JARDS-coupon code has to be connected to his username (ab123456).
  • The HPC account, which corresponds to the external project member’s username (ab123456), is generated automatically.
  • Finally, the invitee’s email address is added to the RWTH Compute Cluster’s mailing list (rzcluster@list.rwth-aachen.de) which is used to distribute important information concerning the cluster’s operation.
  • Using the selfservice online portal the invitee still has to define the password for his HPC account.
