https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/MKL-7-0-Athlon-Linux/m-p/936516#M14129 I posted my problem several days ago (message.id=348), but received a short reply from tim18. So I described my problem more in detail, but received no reply till today. Please, can anybody help me with my problems with MKL 7.0. Here is the description again:<BR /><BR />I just installed Intel MKL 7.0 (with the included installer script, no processor architecture choices etc.) and Intel Fortran Compiler 8 for Linux on an AMD Athlon machine. When I run a simple program, which uses the LAPACK band matrix solver (?gbsv), I get an error:<BR />forrtl: severe (168): Program Exception - illegal instruction<BR />Image PC Routine Line Source<BR />a.out 0804B078 Unknown Unknown Unknown<BR />a.out 4009CEA0 Unknown Unknown Unknown<BR />a.out 0804AF41 Unknown Unknown Unknown<BR />The same program (the same compiled file) on an Intel Pentium 4 machine works fine. I use static linking of the MKL libraries. I didn't use any switches for any particular processor architecture or anything like this.<BR /><BR />I appreciate any useful help.<BR />Thanks, Jakub Wed, 29 Sep 2004 22:55:07 GMT urban 2004-09-29T22:55:07Z https://community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/MKL-7-0-Athlon-Linux/m-p/936516#M14129 I posted my problem several days ago (message.id=348), but received a short reply from tim18.
