CREAM Tests

Introduction

OSG is evaluating various Grid Compute Elements (aka Gatekeepers) to determine which ones it should support. Feature list, ease of use, performance and reliability are all important aspects of the evaluation.

CREAM is a Grid Compute Element developed in EUROPE by gLite:

• The project home page is located at http://grid.pd.infn.it/cream/
• The project code distribution is located at http://glite.web.cern.ch/glite/packages/R3.1/deployment/glite-CREAM/glite-CREAM.asp
• Supported platform: production is SL4 only, SL5 being certified

Client tests

OSG relies hevily on Condor-G for Grid submissions, so it was used for the client testing.

Condor-G only added functional support for CREAM in v7.3.2. Unfortunately that release has VOMS-related bugs that make it unusable in practice, so the upcoming 7.4.0 will be the first one to be usable.

Our group has however collaborated with the Condor team for a long time to get to a release of Condor-Gwith CREAM support. Details can be found on the CREAM Support for CMS page.

Server tests

CREAM can only be installed from RPMs on a SL4 node.
Thawan Kooburat from Madison has done it before in the US and is willing to help.

Waiting for Terrence to get the needed node.
