Comparison between OpenMP for thread programming model and MPI for message passing programming model will be conducted on multicore shared memory machine architectures in order to find which has a better performance in terms of speed and throughput. Application used to assess the scalability of the evaluated parallel programming solutions is matrix...
Article
The current trend of multicore architectures on shared memory systems underscores the need of parallelism. While there are some programming model to express parallelism, thread programming model has become a standard to support these system such as OpenMP, and POSIX threads. MPI (Message Passing Interface) which remains the dominant model used in h...

... OpenMP is the de facto standard application programming interface that supports multi-platform shared memory multi-processing programming. It consists of a set of compiler directives, library routines, and environment variables that influence runtime behavior (Chapman et al., 2007; Refianti et al., 2011). MPI communication has certain weaknesses related to the overhead involved in application-related types of MPI routines (e.g., blocking and collective) as well as message size and network-related factors such as network contention. ...
