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.

Optimized Parallel Reduction for Regular and Irregular Segments on GPU

Concurrency and Computation: Practice and Experience, Volume 38, Issue 8, April 2026.
ABSTRACT Reduction is an operation that combines all the elements of a collection by applying a binary operation, such as sum, maximum, or minimum, to all the elements to obtain a single resulting value. This paper investigates implementation strategies for both segmented and non‐segmented reduction on GPUs.

Optimising Multiprocessor Image-Based Control Through Pipelining and Parallelism

IEEE Access, 2021
Image-based control (IBC) systems have a long sensing delay due to compute-intensive image processing. Modern multiprocessor IBC implementations consider either parallelisation of the sensing task or pipelining of the control loop to cope with this long ...

Efficient Scheduling Algorithms for Multicore Cyclic Executives With Precedence and Exclusion Relations

Concurrency and Computation: Practice and Experience, Volume 38, Issue 5, March 2026.
ABSTRACT Cyclic executives (CEs) offer the advantage of ensuring complete determinism with minimal runtime overhead, often making them the preferred choice for safety‐critical real‐time systems. However, generating CEs for multicore processors while addressing task precedence and exclusion relations presents significant challenges.

Evaluation of the Proposed Hybrid Multiprocessor Real-Time Scheduling Approach with Partitioned and Global Approaches

MATEC Web of Conferences, 2019
Generally, multiprocessor real-time scheduling algorithm fall into two basic approaches, partitioned and global. The hybrid solution that we proposed applies the partitioned scheduling approach to the task set until all processors have been filled.
