Getting started

The aim of this section is to point you in the right direction to get started within the C-SCALE ecosystem.

These pages are targeted to users already onboarded onto the C-SCALE federation. If you want to become a user email info<at>c-scale.eu.

Create a user account

Cloud and HTC/HPC services in C-SCALE currently require separate accounts. Please follow instructions below depending on the service that you are going to access.

Cloud

The user account to access Cloud services is provided by EGI Check-In. Steps to create your Check-In account can be found in the EGI Documentation.

HTC/HPC

The user account to access HTC/HPC services is provided by SURF Research Access Manager (or SRAM). Log into SRAM with your preferred Identity Provider and upload your public SSH key to your profile page.

Join user groups

After creating your user account the next step is to join the relevant user group. So far we have created a user group per Use Case. Therefore, search for the given name of your Use Case and join the appropriate group.

Cloud

The information about user groups for Cloud services is available in EGI Operations Portal. Search for "C-SCALE" to find all the available groups:

User groups in the Cloud federation are also known as Virtual organisations (or VOs), and the links above are called VO ID Cards.

Users will have to visit the enrolment URL to request access. Each petition needs to be approved by the corresponding VO manager. The enrolment URL and the VO manager for each user group can be found in each VO Card.

HTC/HPC

The information about user groups for HTC/HPC services is available in SRAM Collaborative Organisation (or COs)

So far we have only created a single user group in SRAM for the HiSEA Use Case:

The link above is the Join Request URL that users will have to visit to request access. Each petition needs to be approved by the corresponding CO Admin.
