when I compare the performance of MKL-LAPACK with an ifc compiled version of the netlib LAPACK, MKL 6.1.1 is almost two times slower.
I use "MKL_SERIAL=yes" on a dual Xeon system running Redhat 9.
MKL is linked with
"-L/opt/intel/mkl61/lib/32 -lmkl_lapack -lmkl_ia32 -lguide -lpthread".
Is there a mistake in how I use MKL ?
