Using the Grid
A Quick Start Howto for GlueX Members
The GlueX collaboration is registered as a Virtual Organization (VO) within the Open Science Grid (OSG). One requirement for all VO's is that someone within the collaboration be the primary point of support for the members of the VO, and provide both documentation and assistance in problem-solving for users of grid resources and tools within the collaboration. I am that point of support for GlueX members, for the period leading up to the start of physics data taking. In return for the support I provide to Gluex VO users, I have direct access to experts within the OSG central support to help with issues that are beyond my control or expertise. This document is only the starting point for my support to GlueX members. Feedback on the accuracy, organization, and general usefulness of this page will be appreciated.
Who should read this document?
This document was written for those directly involved in the production of large-scale physics simulation data sets, and the end-users who want easy access to these data for carrying out physics analyses. In the past this has primarily been graduate students. Blake Leverington has written a detailed beginner's guide based on his experience, and Jake Bennett has provided a separate instructions page addressing issues he encountered that were not covered by Blake. Those pages will be useful to those who find this document assumes too much background knowledge, or uses too much grid jargon. If you just want to get started with a minimum of verbage, and don't need every term defined and concept explained, this is the place to start.
Before you can start to use the grid, you need to install two objects in your login environment: your personal grid certificate, and the OSG Client Software bundle. If you have never had a grid certificate, go to this separate page for instructions on how to obtain one and have it registered with the Gluex VO.
