Globus

Globus is a service that enables high-performance and convenient data transfer and sharing of large amounts of data.

Using Globus on Cirrus

There are two different Globus Collections (formerly known as an endpoint) that link to Cirrus file systems:

Collection name Cirrus file system
CephFS /home
NAIDIN /epccfs

A full step-by-step guide on transferring data to/from Cirrus is provided below.

Step-by-step example

  1. Navigate to https://app.globus.org.
  2. Log in with your Globus identity (this could be a globusid.org or other identity).
  3. In File Manager, use the search tool to search for the relevant collection (i.e. "CephFS" or "NAIDIN"). Select it.
