In this paper we consider different methods for exchanging data among processors in parallel computers. The most common data exchange operations in parallel numerical methods are examined and different methods for performing them efficiently on each of several ensemble architectures are proposed and analyzed. Our objective is to compare the performance of each particular architecture on each of the data exchange operations.
