I get the result attached as csv file. Can you please help me with pointers to what i can do now to improve the speed of the program. Major portion of the time is spent in zgemm3m for amtrix multiplications and matrix inverse using zgesv (or getrf and getri ). I am not able to understand the timing information obtained. <BR /><BR />My computer has dual quad core(E5240) 2.493 GHz<BR /><BR /> Sun, 25 Mar 2012 21:56:39 GMT Dharma 2012-03-25T21:56:39Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/Help-with-understanding-vtune-results/m-p/784792#M1760 Hello,<BR /> I ran a lightwieight hotspot analysis on my code.
