abstract = "We prove the correctness of optimized parallel
implementations of a generalized broadcast, in which a value
b is distributed to a sequence of processors, indexed from 0
upwards, such that processor i receives g^i b (i.e., some
function g applied i times to b). Its straight-forward
implementation is of linear time complexity in the number of
processors. This type of broadcast occurs when combining
scans with an ordinary broadcast. The optimized parallel
implementations we describe is based on an odd-even tree and
has logarithmic time complexity.",
