This paper reports the design and implementation of Open-SHMEM over MPI using new one-
sided communication features in MPI-3, which include not only new functions (eg remote …

OpenSHMEM is an open standard that brings together several long-standing, vendor-
specific SHMEM implementations that allows applications to use SHMEM in a platform …

Massively parallel simulations of transport equation systems call for a paradigm change in
algorithm development to achieve efficient scalability. Traditional approaches require time …

Achieving good application performance on a modern compute cluster of multi-core, multi-
socket, NUMA-aware systems can be challenging. In this paper, we use VASP, a popular ab …

Inter-processor communication is a critical factor for performance at scale. In order to
achieve good performance, communication overheads should be minimized. The fabric …

Abstract High Performance Computing (HPC) has grown to encompass many new
architectures and algorithms. The Top500 list, which ranks the world's fastest …

Reducing latency and increasing the throughput of issued data transfers is a core
requirement if we are to meet the needs of future systems at scale, and therefore, fast …

The ever increasing scale of modern high performance computing platforms poses
challenges for system architects and code developers alike. The increase in core count …
