Vendor Documentation
- Intel Math Kernel Library - Full Documentation

- provides BLAS, Lapack, ScaLapack, FFTs (including an FFTW interface)
- Link line advisor
Carbon specifics
- Avoid specifying absolute library paths in your Makefile unless you wish to select a specific version. The user environment is normally correctly set up.
- Loading the MKL module does not yet tell the linker where to find the library. The most convenient place is to modify the Makefile similar to the following:
LDFLAGS += -L$MKLROOT/lib/em64t
or, starting with 10.3.x:
LDFLAGS += -L$MKLROOT/lib/intel64
- Link examples:
# 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.
- see HPC/Carbon_Cluster_-_Getting_started#Example_job_file for controlling OpenMP execution.
