Overview
Globus Online (GO) is a service that facilitates high throughput data transfer among its endpoints. Many other Universities and Laboratories have endpoints with the GO. SLAC has an public endpoint (slac#osg) that can access most of the NFS, GPFS and Lustre storage managed by the Scientific Computing Service of the SLAC Computing Division.
Using Globus Online at SLAC
The use Globus Online with SLAC, you need three things
- A free Globus Online account
- A SLAC unix computer account
- Have SLAC enable your to use the SLAC endpoint
You can open a free account at Globus Online web page (below) and manage data transfers through the Web UI
GO also provides a Command Line Interface (CLI). You can access the CLI by ssh to cli.globusonline.org.
Once you have a SLAC unix computer account, e-mail unix-admin@slac.stanford.edu to enable you to access the SLAC endpoint (slac#osg).
Delegate Usage Authorization to Stake Holders (FYI only)
The System Security Plan (SSP) for GlobusOnline (approved on Dec. 13, 2012, RT# 361857) permits one week proxy lifetime by default (and maximum), and delegate to the stake holders the privilege of authorizing users to use GO systems.
We have setup several AFS groups containing lists of users that are authorized to use GO. These AFS groups are globusonline:kipac, globusonline:lcls, etc. People in their respected owning group, globusonline:owner-* are stake holders that can authorize and remove GO users on their systems. A cron job running hourly on machines with globusonline=XXX options in /etc/taylor.opts will update the access privilege according to these AFS groups.
