How to Get Access to T2KND280 computing resources at CERN

Introduction

• You need to be CERN registered and have a CERN account.
  • About the Account Management service
    • Information for newcomers
    • Information for End Users
    • Information for Supervisors, Team Leaders and Group Administrators
• Be aware you must choose np-comp UNIX computing group
  • https://resources.web.cern.ch/resources/Manage/Linux/Settings.aspx?login=​​
• Registered to the corresponding e-group (depending on which protoDUNE activity you're member):
  • TPC-EOI-at-CERN
  • by default you have read access to the corresponding EOS space
  • write/full and rights have only restricted persons, defined in the e-group: eos-experiment-cenf-t2knd280-writers. To obtain such access, if you're eligible, send email to EOS T2KND280 admins support

How to access to t2knd280 experimental EOS space from lxplus computing cluster

T2KND280 experimental EOS space is located at /eos/experiment/neutplatform/t2knd280.
A user to have access needs to be a member of the np-comp UNIX group.
Ensure that the users who will access the space have the correct primary UNIX group.
Otherwise get them to change it in the accounts setting page
https://resources.web.cern.ch/resources/Manage/Linux/Settings.aspx?login=YOUR_UNIX_LOGIN

The automatic EOS endpoint setting use your group membership to sort you into an experiment. 

If this does not work for you, you can just specify your endpoint via an environment variable: 
export EOS_MGM_URL=root://eospublic.cern.ch 

About CERNBox Personal space Installation:

• Keep in mind: you might want to look into CERNBOX or EOS as a storage solution. To activate your CERNBox personal storage space (1 TB, up to 1 million files and the maximum size of a single file is 8GB, hosted in the CERN Computer Center): login to https://cernbox.cern.ch (using your CERN account and password).
• FYI : There is also client for mobile phones and fixed computers that allow sync. For installation and configuration use the link
• (e.g. Linux http://cernbox.cern.ch/cernbox/doc/linux.html straightforward but then we need to use X11 to access client).
• https://cern.service-now.com/service-portal/article.do?n=KB0002996
• https://cern.service-now.com/service-portal/article.do?n=KB0004529
• https://cern.service-now.com/service-portal/article.do?n=KB0004801
• and you can also browse your files: https://cernbox.cern.ch

How to access personal EOS space under T2KND280

The initial and mandatory step to using your CERNBox is to create it.  
Use any Web browser to go to 'https://cernbox.cern.ch' 
and login via the CERN Single Sign-On page with your username and password (NICE or lxplus).

This first connection creates your CERNBox storage space (1 TB, up to 1 million files), hosted in the CERN Data Centre.

To activate the corresponding service go to:
https://resources.web.cern.ch/resources/Manage/EOS/Default.aspx?login=YOUR_UNIX_LOGIN

Please take into account, personal EOS space (/eos/user/<firstletter_login_name>/<login_name>) has nothing to do with experimental 
EOS space (/eos/experiment/neutplatform/t2knd280/...). 

How to best access EOS from central services (LXPLUS and LXBATCH)

If you still have problems you can get help through the CERN Service Portal.
