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.

Boosting Parallel Applications Performance on Applying DIM Technique in a Multiprocessing Environment

International Journal of Reconfigurable Computing, 2011
Limits of instruction-level parallelism and higher transistor density sustain the increasing need for multiprocessor systems: they are rapidly taking over both general-purpose and embedded processor domains.

Generating Stable and Metastable Critical Points in Uncertain Systems via Flow‐Based Models

Expert Systems, Volume 43, Issue 3, March 2026.
ABSTRACT This work proposes the use of conditional flow‐based generative models to learn an approximation of the distribution of the critical points of a cost function. This approximation is used to incrementally identify all critical points, in the feasible domain of said function, by iteratively alternating the sampling of the distribution and the ...

LeF‐MTP: Prioritizing GNN Test Cases by Fusing Model Uncertainty and Feature‐Space Confusability

Computational Intelligence, Volume 42, Issue 1, February 2026.
ABSTRACT Graph Neural Networks (GNNs) are widely applied in 3D computer vision tasks. However, validating their reliability is limited by the high cost of labeling large‐scale test data. Existing test case prioritization techniques for deep learning often rely on single‐dimensional heuristics or mutation‐based analysis (e.g., GraphPrior, PCPrior ...

Time‐ and Behaviour‐Preserving Execution of Determinate Supervisory Control

IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.
The activity framework is a model‐based framework incorporating a model of activities with determinate timing and behaviour, and a strong mathematical foundation based on max‐plus algebra that allows efficient timing analysis and optimisation of CPS. Preserving the specified behaviour and the model‐predicted timing in an implementation is challenging ...

Three Algorithms for Parallel Graph Summarization

Expert Systems, Volume 43, Issue 1, January 2026.
ABSTRACT Most graph summarization algorithms are tailored to a specific graph summary model and were designed for one‐time computations only, that is, batch‐based computations. We developed a universal approach for parallel graph summarization and three algorithms to compute graph summaries—a batch‐based algorithm for static graphs, an incremental ...

Vehicular Traffic Networks Simulation: Towards the Implementation of a High‐Performance Computing Simulator

Complexity, Volume 2026, Issue 1, 2026.
This work presents a comparison of different software and hardware implementations of a traffic simulator using a fluid‐based mesoscopic model. The model represents Vehicular Traffic Networks (VTNs) based on the flow resulting by the interconnection of dynamical agents associated to street segments and intersections.

Mathematical theory of multiprocessor control systems and its applications [PDF]

Computer Science Journal of Moldova, 1995
The peculiar feature of cybernetic control systems is a feedback interaction with a controlled object. The abstract model of such an interaction may be based on the control and operating automata composition originating in the abstract computer model ...
