WebBlelloch is a surname. Notable people with the surname include: Guy Blelloch, American professor of computer science. Ian Blelloch (1901–1982), British colonial administrator … Weboperation can be any associative (but not necessarily commutative) operator [Blelloch, 1990]. Par-allel implementations of all-prefix-sums are usually called parallel prefix or scan, emphasizing that the operator can be varied. Parallel prefix is one of the fundamental algorithms of computer sci-ence, and it has been much studied.
