We present a parallel version of BIRCH withthe objective of enhancing the scalability without compromising on the quality of clustering. the incoming data is distributed in a cyclic manner (or block cyclic manner if the data is bursty) to balance the load among processors. the algorithm is implemented on a message passing share-nothing model. Experiments show that for very large data sets the algorithm scales nearly linearly withthe increasing number of processors. Experiments also show that clusters obtained by PBIRCH are comparable to those obtained using BIRCH.
this paper presents a methodology to develop more modular parallelapplications, based on aspect oriented programming. Traditional object oriented mechanisms implement application core functionality and parallelisatio...
