All the results should be accurate within certain tolerances. There is <A href="http://software.intel.com/en-us/articles/getting-reproducible-results-with-intel-mkl/">an article</A> on the knowledgebase that discusses reasons for the variations sometimes seen in results. It includes steps that can be taken to sometimes make results consistent.<BR /><BR />If you do have problems in accuracy, please give us some specifics: A test case, your results, the data you use for input, etc.<BR /><BR />Todd Fri, 19 Nov 2010 18:15:14 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/accuracy-of-cblas-sgemv-function/m-p/781473#M1501 Todd_R_Intel 2010-11-19T18:15:14Z
