An Assessment of the VOMS and GridShib VO Management Systems

Abstract

In the past, high performance computing consortia in Canada have received separate grants for resources. Furthermore, a consortium s resources have been primarily intended for users local to member institutions of the consortium. Recently, the seven high performance computing consortia in Canada worked together on a successful single CFI (Canadian Foundation for Innovation) grant proposal, called the National Platform Fund. While users will still be expected to try to meet computing needs from their local consortium first, there will be a greater emphasis on the national sharing of resources. With a much larger user base nationally, mechanisms for authenticating users and authorizing access to resources need to be explored.
