ORC-OpenMP: An OpenMP Compiler Based on ORC [PDF]

, 2004
This paper introduces a translation and optimization framework for OpenMP, based on the classification of OpenMP translation types. And an open source OpenMP compiler, which implements this framework is also introduced as a high performance research platform for Linux/IA-64.

ThreadMonitor: Low‐Overhead Data Race Detection Using Intel Processor Trace

Concurrency and Computation: Practice and Experience, Volume 38, Issue 2, January 2026.
ABSTRACT Data races are among the most difficult multithreading bugs to find, due to their non‐deterministic nature. This and the increasing popularity of multithreaded programming have led to the need for practical automated data race detection. In this context, dynamic data race detectors have received more attention, compared to static tools, owing ...

A Python/Fortran Implementation of the Lattice‐Boltzmann Kernel on Multiple GPU Using the OpenACC Framework

Concurrency and Computation: Practice and Experience, Volume 38, Issue 1, January 2026.
ABSTRACT The increasing availability of GPU accelerated architectures for high‐performance computing presents new opportunities for scientific software but also challenges due to the complexity of porting legacy codes to accelerator platforms. Directive‐based programming models such as OpenACC offer a minimally intrusive pathway to exploit GPU ...

OpenMP extensions for FPGA accelerators [PDF]

2009 International Symposium on Systems, Architectures, Modeling, and Simulation, 2009
Reconfigurable computing is one of the paths to explore towards low-power supercomputing. However, programming these reconfigurable devices is not an easy task and still requires significant research and development efforts to make it really productive.

Mapping Thermal Conductivity at the Atomic Scale: A Step toward the Thermal Design of Materials

physica status solidi (b), Volume 263, Issue 1, January 2026.
The site‐projected thermal conductivity method resolves the local thermal conduction contribution per atom by decomposing the Green–Kubo thermal conductivity tensor under the harmonic approximation. It highlights thermally active sites and “thermal defects” within disordered or amorphous materials, enabling spatially resolved insights into atomic‐scale

Implementation and Evaluation of Parallel Computing Approaches for Large‐Domain, Process‐Based Hydrologic Simulations

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 1, January 2026.
Abstract Process‐based hydrologic simulations in large domains generally require intensive computing resources. In this study, we implement various parallelization approaches within a process‐based hydrologic solver, SUMMA, including the Message Passing Interface (MPI), Open Multi‐Processing (OMP), and the Actor Model, to enable high‐performance ...

BioEM: GPU-accelerated computing of Bayesian inference of electron microscopy images

, 2016
In cryo-electron microscopy (EM), molecular structures are determined from large numbers of projection images of individual particles. To harness the full power of this single-molecule information, we use the Bayesian inference of EM (BioEM) formalism ...
