Detailed Description

template<class IT, class NT>
class FullyDist< IT, NT, typename CombBLAS::disable_if< CombBLAS::is_boolean< NT >::value, NT >::type >

The full distribution is actually a two-level distribution that matches the matrix distribution In this scheme, each processor row (except the last) is responsible for t = floor(n/sqrt(p)) elements. The last processor row gets the remaining (n-floor(n/sqrt(p))*(sqrt(p)-1)) elements Within the processor row, each processor (except the last) is responsible for loc = floor(t/sqrt(p)) elements. Example: n=103 and p=16 All processors P_ij for i=0,1,2 and j=0,1,2 get floor(floor(102/4)/4) = 6 elements All processors P_i3 for i=0,1,2 get 25-6*3 = 7 elements All processors P_3j for j=0,1,2 get (102-25*3)/4 = 6 elements Processor P_33 gets 27-6*3 = 9 elements Both derived classes, whether sparse or dense, are distributed to processors based on their "length", so that a conversion does not need any communication between sparse and dense formats
