The majority of time of my programm is matrix-vector multiplication, which is performed by mkl_ddiamv. In my task manager I always see, that ONLY ONE thread is busy by my programm process. I use Intel C++ Compiler 14.0. I try to take many different sizes of multiplicated arrays. There is no difference. I unsuccessfully tried to find some info about the reason of one-thread calculation.&nbsp;</P> <P style="font-size: 12px;">Is it normal behavior of this function or I do something wrong? Should I change some of my project's properties or include something to launch my app multi-threated?</P> <P>&nbsp;</P> Tue, 23 Jun 2015 13:28:28 GMT https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/mkl-ddiamv-multi-thread-support/m-p/1050290#M21126 Aaron_B_1 2015-06-23T13:28:28Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/mkl-ddiamv-multi-thread-support/m-p/1050291#M21127 <P>this function is single-threaded until the latest version.
