MKL in Theta
1) Set env. variable MKLROOT=/opt/intel/mkl-knl/mkl
2) Consult the following website to determine the compile/link command line options to use:
For example, to compile an OpenMP program that calls the MKL Lapack routine DGEMM would require the following command line:
$ ftn -static -extend-source -qopenmp -O2 dgemm.f -Wl,--start-group ${MKLROOT}/lib/intel64/libmkl_intel_lp64.a ${MKLROOT}/lib/intel64/libmkl_core.a ${MKLROOT}/lib/intel64/libmkl_intel_thread.a -Wl,--end-group -lpthread -lm
