MathKeisan is a tuned collection of mathematical libraries for NEC high-performance computers. There is a version for the NEC SX vector machines running SUPER-UX, and a version for the NEC Itanium® Processor Family (IPF) machines running Linux.
MathKeisan contains assembly code for BLAS subprograms. There are shared memory parallel (OpenMP) versions of BLAS, FFT, Solver, and IPF LAPACK. There are distributed memory parallel (MPI) libraries: BLACS, ScaLAPACK, ParMETIS, and PARPACK.
The FFT, LAPACK, and PARDISO libraries in MathKeisan for IPF are from the Intel® Math Kernel Library (MKL). Part of BLAS in MathKeisan for IPF is from MKL.
MathKeisan libraries are listed in Table 1.

Various fonts are used in the text, depending on what the text is for:
Pathnames like /opt/MathKeisan, environment variables like OMP_NUM_THREADS, library names like libblas.a, and Fortran/C code which is descriptive, such as real(kind=4).
