MKL - Math Kernel Library

General Information

Short Description: Intel math kernel library

Long Description:
The Math Kernel Library (MKL) contains the complete set of functions from the basic linear algebra subprograms (BLAS), the extended BLAS (sparse), and the complete set of LAPACK routines. In addition, there is a set of fast Fourier transforms in single- and double-precision, real and complex data types with both Fortran and C interfaces. The library also includes the cblas interfaces, which allow the C programmer to access all the functionality of the BLAS without considering C-Fortran issues.

Usage Information:
MKL 10 now incorporates the "cluster" libraries of BLACS and ScaLAPACK 1.7, plus additional distributed functionality. To add MKL 10.0 to your environment put:
+intel-mkl-10.0.3.020
in your ${HOME}/.soft file.

Note: Please do not use the Intel compiler option -fast as it adds -static and there are not static libraries for the SGI MPT (MPI) libraries. If you would like to link to the Intel compiler libraries statically please add -static-intel -static-libgcc.

To link to the libraries

BLAS and LAPACK

no MKL threads

-Wl,-Bstatic -Wl,--start-group -L ${MKL_HOME}/lib/64 -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -Wl,--end-group -Wl,-Bdynamic

The dynamic linking scheme can be subject to runtime numerical issues:
-L${MKL_HOME}/lib/64 -lmkl_intel_lp64 -lmkl_sequential -lmkl_core

MKL threaded

-L${MKL_HOME}/lib/64 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -lguide -lpthread

If you used the libscs_mp library under ProPack4, this is what you would replace it with for Intel MKL.

ScaLAPACK with SGI MPT

no MKL threads

-L ${MKL_HOME}/lib/64 -lmkl_scalapack_lp64 -lmkl_blacs_sgimpt_lp64 -Wl,-Bstatic -Wl,--start-group -L ${MKL_HOME}/lib/64 -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -Wl,--end-group -Wl,-Bdynamic -lmpi

The dynamic linking scheme can be subject to runtime numerical issues:
-L${MKL_HOME}/lib/64 -lmkl_scalapack_lp64 -lmkl_blacs_sgimpt_lp64 -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -lmpi

Integer*8 interface

For cases which exceed indexing of 2^32-1, the integer*8 interface ilp64 can be used. Simply replace lp64 as in above or below with ilp64 and compile your code with -i8 if needed.

This is the equivalent of using ProPack4 libscs_i8.

Issues with use of dyanamically linked libraries

In some cases, using the dynamically linked libraries can cause runtime memory problems. If you encounter error messages such as
cannot allocate memory for thread-local data: ABORT
please use the statically linked libraries as follows:

BLAS and LAPACK

no MKL threads

-L${MKL_HOME}/lib/64 -Bstatic -lmkl_intel_lp64 -lmkl_sequential -lmkl_core -Bdynamic

MKL threaded

-L${MKL_HOME}/lib/64 -Bstatic -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -Bdynamic -lguide -lpthread
