Optimized Convex Hull With Mixed (MPI and OpenMP) Programming On HPC
"... As a programmer, one is aspired to solve ever larger, more memory intensive problems, or simply solve problems with greater speed than possible on a sequential computer. A programmer can turn to parallel programming and parallel computers to satisfy these needs. Parallel programming methods on paral ..."
Abstract

Performance evaluation of MPI, UPC and OpenMP on multicore architectures
- Proceedings of the 16th European Users’ Group Meeting on Recent Advances in Parallel Virtual Machine and Message Passing Interface
, 2009
"... Abstract. The current trend to multicore architectures underscores the need of parallelism. While new languages and alternatives for supporting more efficiently these systems are proposed, MPI faces this new challenge. Therefore, up-to-date performance evaluations of current options for pro-gramming ..."

-gramming multicore systems are needed. This paper evaluates MPI per-formance against Unified Parallel C (UPC) and OpenMP on multicore architectures. From the analysis of the results, it can be concluded that MPI is generally the best choice on multicore systems with both shared and hybrid shared/distributed memory
IMPLEMENTATION AND EVALUATION OF MPI+OPENMP PROGRAMMING MODEL ON DAWNING3000 ABSTRACT
"... SMP cluster (CLUMPs) architecture has been widely used to provide scalable high performance computers recently. One distinctive feature over traditional parallel computer architecture is its hybrid memory model, shared memory inside the node and message passing between the nodes. In this paper, we s ..."

study the hybrid programming model of MPI+OpenMP on CLUMPs architecture. We analyze the implementation mechanism of MPI+OpenMP and give some suggestions about this hybrid programming model on CLUMPs. We also conduct experiments on Dawning3000 super parallel computer, which is CLUMPs architecture
Detecting threadsafety violations in hybrid openmp/mpi programs.
- In Proceedings of the 2015 IEEE International Conference on Cluster Computing,
, 2015
"... Abstract-We propose an approach by integrating static and dynamic program analyses to detect threadsafety violations in hybrid MPI/OpenMP programs. We innovatively transform the thread-safety violation problems to race conditions problems. In our approach, the static analysis identifies a list of M ..."

A Hybrid Approach of OpenMP for Clusters
- Proceedings of the 17th ACM SIGPLAN Symposium on Principles and Practice of Parallel Programming (PPOPP ´12). NY, USA: ACM
, 2012
"... Abstract We present the first fully automated compiler-runtime system that successfully translates and executes OpenMP shared-address-space programs on laboratory-size clusters, for the complete set of regular, repetitive applications in the NAS Parallel Benchmarks. We introduce a hybrid compiler-r ..."

High Performance Computing Using MPI and OpenMP on Multi-core Parallel Systems
"... The rapidly increasing number of cores in modern microprocessors is pushing the current high performance computing (HPC) systems into the petascale and exascale era. The hybrid nature of these systems—distributed memory across nodes and shared memory with non-uniform memory access within each node—p ..."

—poses a challenge to application developers. In this paper, we study a hybrid approach to programming such systems – a combination of two traditional programming models, MPI and OpenMP. We present the performance of standard benchmarks from the multi-zone NAS Parallel Benchmarks and two full applications
Development of Mixed Mode MPI / OpenMP Applications
- In WOMPAT 2000
, 2000
"... MPI / OpenMP mixed mode codes could potentially offer the most effective parallelisation strategy for an SMP cluster, as well as allowing the different characteristics of both paradigms to be exploited to give the best performance on a single SMP. This paper discusses the implementation, development ..."
