MPI‐Based Approaches to Overlap Computation and I/O in Geophysical Simulations

Concurrency and Computation: Practice and Experience, Volume 38, Issue 7, April 2026.
ABSTRACT Geophysical simulations, such as wave propagation, are often constrained by I/O bottlenecks, where a significant portion of the execution time is spent writing data to disk. This process frequently leaves expensive computational resources, such as GPUs, idle, directly impacting both performance and energy consumption.

Linking Model Parameter Sensitivities With Hydrological Process Behavior Along Elevation Gradients in Alpine Terrain

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Analyzing process interactions in hydrological systems typically requires catchment‐scale hydrological models, where greater model complexity enhances the representation of physical process behavior but also poses challenges related to parameter equifinality.

Adaptive energy minimization of OpenMP parallel applications on many-core systems [PDF]

Energy minimization of parallel applications is an emerging challenge for current and future generations of many-core computing systems. In this paper, we propose a novel and scalable energy minimization approach that suitably applies DVFS in the ...

Predictable parallel programming with OpenMP [PDF]

, 2018
This chapter motivates the use of the OpenMP (Open Multi-Processing) parallel programming model to develop future critical real-time embedded systems, and analyzes the time-predictable properties of the OpenMP tasking model.

Portable Compilers for OpenMP [PDF]

, 2001
The recent parallel language standard for shared memory multiprocessor (SMP) machines, OpenMP, promises a simple and portable interface for programmers who wish to exploit parallelism explicitly. In this paper, we present our effort to develop portable compilers for the OpenMP parallel directive language. Our compiler consists of two parts. Part one is

Analysis of Parallel Algorithms on SMP Node and Cluster of Workstations Using Parallel Programming Models with New Tile-based Method for Large Biological Datasets

Bioinformatics and Biology Insights, 2016
Sequence alignment is an important tool for describing the relationships between DNA sequences. Many sequence alignment algorithms exist, differing in efficiency, in their models of the sequences, and in the relationship between sequences.
