UCLA Physics Saxon Cluster -- New User Information

How to Apply for a Login ID as a New User

All new UCLA users of the Saxon Cluster must be approved by Professor Saltzberg. To apply for a login id on the Saxon Cluster, click on this link. If you have never had a login id on an ATS-hosted cluster before, click on New User Registration. Otherwise, click on Add Resources.

When you click on the link, you will be taken first to the UCLA Federated Authentication Service to authenticate as a member of the UCLA community. To do so you will need your UCLA Logon Id and Password. If you do not have one, please go and get one before continuing.

In order to use the Saxon Cluster you will have to: 1) select the Saxon Cluster as a resource and 2) select Professor David Saltzberg's name from the Sponsor list. You login id will be added to the Saxon Cluster shortly after Professor Saltzberg approves your application.

Apply for a Certificate

In order to submit jobs to the Saxon Cluster, you need a certificate issued by a participating Virtual Organizations (VOs). If you are already participating in one or another of these organizations you would normally already have a certificate. If you do not have a certificate, follow these instructions to get a DOEGrids issued certificate:

  • Using a web browser on your personal machine go to http://www.doegrids.org/pages/cert-request.html. You must use your own web browser because after the certificate is passed to you, it will reside in your web browser until it expires.

  • Follow the instructions on that page. One of the instructions will be to fill in a form at: https://pki1.doegrids.org/ca. In this form you will have to provide your name and email address. For Affiliation (registration authority) select OSG and for VO Name select CMS.

  • When your certificate has been successfully issued, you will receive an email that contains a link to a page containing all your certificate information. Open that page in your browser and click on the Import Your Certificate button at the bottom of the page.

  • Following the instructions, export the certificate from your browser. It will have either a .p12 or .pfx extension.

  • Enter the following commands to extract usercert.pem and userkey.pem to your $HOME/.globus subdirectory:
    openssl pkcs12 -in YourCert.p12 -clcerts -nokeys -out
    openssl pkcs12 -in YourCert.p12 -nocerts -out
    Replace YourCert.p12 with the name of the certificate you exported.

  • Make sure the permissions on the certificate are correct.
    cd .globus
    chmod u+rw userkey.pem
    chmod o-rw userkey.pem
    chmod g-rw userkey.pem

Email the Saxon Cluster Administrators the Certificate Subject from your usercert.pem File

Ther certificate subject will look something like:

"/DC=org/DC=doegrids/OU=People/CN=John Doe 5555"
