MTGP64 parameters.
Some element is redundant to keep structure simple.
pos is a pick up position which is selected to have good performance on graphic processors. 3 < pos < Q, where Q is a maximum number such that the size of status array - Q is a power of
poly_sha1 is SHA1 digest of the characteristic polynomial of state transition function. SHA1 is calculated based on printing form of the polynomial. This is important when we use parameters generated by the dynamic creator which
mask This is a mask to make the dimension of state space have just Mersenne Prime. This is redundant.
