SFMT-jump Documentation

This is SIMD oriented Fast Mersenne Twister pseudorandom number generator(SFMT) with jump function. This Project provides jump function of SFMT.

We are very sorry but we don't support either BIG ENDIAN or altivec in this version.

There are two steps for jumpping.

  1. Calculate jump polynomial using characteristic polynomial.
    • calc-jump executable file calculates a jump polynomial.
    • calc-jump is written in C++ language and needs NTL for compile.
    • Additionally, users can call sfmt::calc_jump(std::string& jump_str, NTL::ZZ& step, NTL::GF2X& characteristic) in SFMT-calc-jump.hpp from their programs.
    • jump steps used above is based on internal state, i.e, 32-bit integers are skipped 4 * jump steps, and 64-bit integers are skipped 2 * jump steps.
  2. Change internal state of SFMT into jumpped state.

Caution: The jump polynomial calculated using a characteristic polynomial is only available for jumpping SFMT states which has the characteristic polynomial.
