1、cudpp current support Parallel reduction? and how to use cudpp to run reduction
2、cudpp support the Matrix of squares?
for example:
the matrix is:
1 2 3
4 5 6
7 8 9
and the matrix of squares is :11+22+…+9*9

No, CUDPP doesn’t support reductions (unless you count scan). You might want to try Thrust, which does:
