+		The purpose of Double precision SIMD-oriented Fast Mersenne Twister (dSFMT)
+		is to speed up the generation by avoiding the expensive conversion
+		of integer to double (floating point). dSFMT directly generates
+		double precision floating point pseudorandom numbers which have the
+		IEEE Standard for Binary Floating-Point Arithmetic (ANSI/IEEE Std
+		754-1985) format. dSFMT is only available on the CPUs which use IEEE
+		754 format double precision floating point numbers.
