<div dir="ltr"><div><div><div>Dear Sir <br><br></div>I want to know how can define MKLROOT and Which one system i have to choose (i choose I Linux (Intel ifort 12.0 compiler + mkl ) )<br></div>I install MKL Librery anf ifort compiler (l_mkl_11.0.2.146 and l_fcompxe_2013.3.163)<br>
<br></div>Getting the following error<br><div><br><div> ******************************<br> * Specify compiler options *<br> ******************************<br><br>PLEASE NOTE: Best performance can be obtained with processor specific options. <br>
Very important for speed-up is a optimized BLAS (like mkl, essl, ..), <br>or at least the GOTO- or ATLAS-BLAS instead of the simple "-lblas_lapw"<br><br>For more info see <a href="http://www.wien2k.at/reg_user/faq">http://www.wien2k.at/reg_user/faq</a><br>
searching ....<br> I could not find the mkl-library because MKLROOT is not defined.<br> Please check whether mkl is installed at all and where<br> (mkl is included in new ifort versions, see <a href="http://www.intel.com">www.intel.com</a> )<br>
Without mkl you should install the GOTO-blas or you must use the blas_lapw<br> library (performance loss)<br>Hit Enter to continue <br><br></div></div></div>
