Intel MKL

Intel Math Kernel Library (Intel MKL) is a library of optimized math routines for science, engineering, and financial applications. Core math functions include BLAS, LAPACK, ScaLAPACK, sparse solvers, fast Fourier transforms, and vector math. The routines in MKL are hand-optimized specifically for Intel processors.

Compilation

Compile with intel

#Environment setup
module purge
module load intel/2020
module load intel/2020.mkl
source /cvmfs/sw.el7/intel/2020/mkl/bin/mklvars.sh intel64

    
gcc -L${MKLROOT}/lib/intel64 -Wl,--no-as-needed -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread -lm -ldl  <source_file.c>  -o <output_binary_name>

./<output_binary_name> #Execute binary
