Intel® Math Kernel Library Structure 3To migrate to ILP64 or write new code for ILP64, use appropriate types for parameters ofthe Intel MKL functions and subroutines (see Table 3-5):Table 3-5Integer Types32-bit integersUniversal integers for ILP64/LP64:• 64-bit for ILP64• 32-bit otherwiseUniversal integers for ILP64/LP64:• 64-bit integersFFT interface integers for ILP64/LP64FortranINTEGER*4 orINTEGER(KIND=4)INTEGERwithout specifying KINDINTEGER*8 orINTEGER(KIND=8)INTEGERwithout specifying KINDC or C++intMKL_INTMKL_INT64MKL_LONGBrowsing the Intel MKL Include FilesThe Reference Manual does not explain which integer parameters of a function become64-bit and which remain 32-bit for ILP64. To get to know this, browse the include files,examples, and tests for the ILP64 interface details. For the location of these files, seeTable 3-2. Start with browsing the include files, listed in Table A-2.Some function domains that support only a Fortran interface (see Table A-1) provideheader files for C/C++ in the include directory. Such *.h files enable using a Fortran binaryinterface from C/C++ code. These files can also be used to understand the ILP64 usage.LimitationsAll Intel MKL function domains support ILP64 programming with the following exceptions:• FFTW interfaces to Intel MKL:— FFTW 2.x wrappers do not support ILP64.— FFTW 3.2 wrappers support ILP64 by a dedicated set of functions plan_guru64.• GMP* arithmetic functions do not support ILP64.3-7

For the list of additional interface libraries that can begenerated in these directories using makefiles in the interfaces directory, see UsingLanguage-Specific Interfaces with Intel® MKL. For the contents of the doc directory, seeContents of the Documentation Directory. For the contents of subdirectories in thebenchmarks directory, see LINPACK and MP LINPACK Benchmarks.
