The system as described on this result page was formerly generally available. At the time of this publication, it may not be shipping, and/or may not be supported, and/or may fail to meet other tests of General Availability described in the SPEC OSG Policy document, http://www.spec.org/osg/policy.html This measured result may not be representative of the result that would be measured were this benchmark run with hardware and software available as of the publication date.
