Implementing OpenSHMEM Using MPI-3 One-Sided Communicationnew functions (e.g. remote atomics) but also a newmemory model that is consistent with that of SHMEM.We use a new, non-collective MPI communicator creation routine to allow SHMEM collectives to use their MPI counterparts. Finally, we leverage MPI sharedmemory windows within a node, which allows dire

Analyzing the Energy and Power Consumption of Remote Memory Accesses in the OpenSHMEM Modelvides synchronizing barriers to ensure a consistent view of the distributed memory at different phases of an application. The incorrect use of such interfaces affects the scalability achievable while using a parallel programming model. This study aims at understanding the effects of these constructs

Hybrid Programming Using OpenSHMEM and OpenACCramming models are the natural choice to exploit all the hardware made available on these systems. Previous efforts looking into hybrid models have primarily focused on using OpenMP directives (for shared memory programming) with MPI (for inter-node programming on a cluster), using OpenMP to spawn t

Towards Parallel Performance Analysis Tools for the OpenSHMEM Standarding. The theoretical part covers the mapping of OpenSHMEM’s communication primitives to a generic event record scheme that is compatible with a range of PGAS libraries. The visualization of the recorded events is included as well. The practical parts demonstrate an experimental extension for Cray-SH

Extending the OpenSHMEM Analyzer to Perform Synchronization and Multi-valued Analysis feedback to the users about semantics errors due to incorrect use of the OpenSHMEM API in their programs, thus making development of OpenSHMEMapplications an easier task for beginners as well as experienced programmers. In this paper we discuss the improvements to theOSA tool to perform parallel an

OpenSHMEM Extensions and a Vision for Its Future Directione the SHMEM API with input from the vendors and user community. In 2012, OpenSHMEM specification 1.0 was finalized and released to the OpenSHMEM community for comments. As we move to future HPC systems, there are several shortcomings in the current specification that we need to address to ensure sca

Reducing Synchronization Overhead Through Bundled Communicationd global address space. While communication in this model is efficient, synchronizations must currently be achieved through collective barriers or one-sided updates of sentinel locations in the global address space. These synchronization mechanisms can over-synchronize, or require additional communi

Implementing Split-Mode Barriers in OpenSHMEM performance applications hide latency by keeping a large number of operations in progress asynchronously. Since barriers synchronize all these operations, maximum performance requires that barriers have as little overhead as possible. When some workers arrive at a barrier much later than others, th
