IBM Corporation IBM Power S824 CODE DEFECT (CD) RESULT
Tested by: IBM Corporation Test Sponsor: IBM Corporation Test location: Austin, TX Test date: Oct 12, 2014
SPEC license #: 11 Hardware Availability: Jun-2014 Software Availability: Nov-2014 Publication: Nov 12, 2014
Validation Errors Summary
SPECjbb2013 results have been marked as "Code Defect" due to a bug that impacts the comparability of results. The bug can significantly reduce the amount of work done during the measurement period, resulting in an inflated SPECjbb2013 metric.
