Can someone send us an example makefile which uses the Fortran compiler and mkl to multiple 2 double precision matrices and compiles for mic.
We want to run this program on mic only (for testing).
We have no problems to compile and run on the main processor!
Thanks, Renate

Here you go, a very simple example.This is how you build it for native execution on Xeon Phi (assuming you have Intel Fotran Composer XE installed on your system):
ifort -mmic -I$MKLROOT/include dgemm_example.f -L$MKLROOT/lib/mic -lmkl_intel_lp64 -lmkl_core -lmkl_intel_thread -L$MKLROOT/../compiler/lib/mic -liomp5 -lpthread -lm
