• Intel Math Kernel Library - Documentation

User Notes

• User's Guide – consult Sec. 5 to resolve linker issues, and 32bit vs. 64bit programming
• Reference Manual
• since v10 includes formerly separate Cluster MKL (providing ScaLapack et al.)
• provides BLAS, Lapack, ScaLapack, FFTs (including an FFTW interface)
• Detailed linking instructions; alternate link
• Link example:

 # Sequential:
   -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lpthread

 # OpenMP multi-threaded:
   -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -liomp5 -lpthread

• The FFTW interface of the MKL can be linked by prefixing the above options with one of:

-lfftw2xc_intel
-lfftw2xf_intel
-lfftw3xc_intel
-lfftw3xf_intel

Choose the appropriate version between bindings for FFTW v2 vs. v3 and C vs. Fortran.

• Avoid specifying absolute library paths in your Makefile unless you wish to select a specific version. The user environment is normally correctly set up. To force the library version current at the time of writing, add as first flag to the linker options:

-L$MKLROOT/lib/em64t. The variable $MKLROOTis automatically provided.

• see HPC/Carbon_Cluster_-_Getting_started#Example_job_file for controlling OpenMP execution.
