Computing of multiple tasks simultaneously on multiple processors is called Parallel Computing. The parallel program consists of multiple active processes simultaneously solving a given problem. Parallel computers can be roughly classified as Multi-Processor and Multi-Core. In both these classifications the hardware supports parallelism with computer node having multiple processing elements in a single machine, either in single chip pack or on more than one distinct chip respectively. Parallel programming is the ability of program to run on this infrastructure which is still quite difficult and complex task to achieve. Out of many two different approaches used in parallel environment are MPI and OpenMP, each one of them having their own merits and demerits. Hybrid model combines both approaches in the pursuit of reducing the weaknesses in individual. In proposed approach takes a pair of, Matrices produces another matrix by using Matrix-Vector Multiplication Algorithm. The resulting matrix agrees with the result of composition of the linear transformations represented by the two original matrices. This algorithm is implemented in MPI, OpenMP, and Hybrid mode. The algorithm is tested for number of nodes with different number of matrix size. The results indicates that the Hybrid approach out performs the MPI and OpenMP approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
