| | Compute the global sum of each field in "arr" using the indicated communicator with a reproducible yet scalable implementation based on a fixed point algorithm. The accuracy of the fixed point algorithm is controlled by the number of "levels" of integer expansion, the maximum value of which is specified by max_level. More...
