Hi, I have this array [1 2 3 4 5 6 7 8 9] and i am performing scan operation on that.
I have 3 mpi tasks and each task gets 3 elements then each task calculates its scan and returns result to master task task 0 - [1 2 3] => [1 3 6] task 1 - [4 5 6 ] => [4 9 15] task 2 - [7 8 9] => [7 15 24] Now task 0 gets all the results [1 3 6] [4 9 15] [7 15 24] How can I combine these results to produce final scan output? final scan output of array would be [1 3 6 10 15 21 28 36 45] can anyone help me please?
