Language-specific UsageOptions 7Intel® Math Kernel Library (Intel® MKL) basically provides support for Fortran and C/C++programming. However, not all function domains support both Fortran and C interfaces(see Table A-1). For example, LAPACK has no C interface. Still you can call functionscomprising these domains from C using mixed-language programming.Moreover, even if you want to use LAPACK or BLAS, which basically support Fortran, in theFortran 90 environment, additional effort is initially required to build language-specificinterface libraries and modules, being delivered as source code.The chapter mainly focuses on mixed-language programming and the use oflanguage-specific interfaces. It expands upon the use of Intel MKL in C languageenvironments for function domains that basically support Fortran as well as explains usageof language-specific interfaces and, in particular, Fortran 90 interfaces to LAPACK andBLAS. In this connection, compiler-dependent functions are discussed to explain whyFortran 90 modules are supplied as sources. A separate section guides you through theprocess of running examples of invoking Intel MKL functions from Java.Using Language-Specific Interfaces with Intel® MKLThe following interface libraries and modules may be generated as a result of operation ofrespective makefiles located in the interfaces directory.Table 7-1Interface libraries and modulesFile namelibmkl_blas95.alibmkl_lapack95.alibfftw2xc_intel.alibfftw2xc_gnu.aCommentContains Fortran 90 wrappers for BLAS (BLAS95)Contains Fortran 90 wrappers for LAPACK (LAPACK95)Contains interfaces for FFTW version 2.x (C interface forIntel® compiler) to call Intel MKL FFTs.Contains interfaces for FFTW version 2.x (C interface forGNU compiler) to call Intel MKL FFTs.7-1
