https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Extra-precision/m-p/1051969#M21215 <P>I am evaluating MKL 11.3 for Windows. Could you tell me if MKL provides some functionalities like XBLAS (which supports the extra precision or up to twice the working precision)? I notice that MKL has some high-level functions, e.g., dposvxx, which uses extra precise refinement to compute the solution (at least twice the working precision). So MKL should have some underlying functions which can perform the extra precision. Are those underlying functions coming from XBLAS? Could we access those underlying functions?</P> <P>Thank you very much for your advices.</P> Tue, 29 Sep 2015 07:44:40 GMT XD_J_ 2015-09-29T07:44:40Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Extra-precision/m-p/1051969#M21215 <P>I am evaluating MKL 11.3 for Windows.
