Vector Database Management System for Similarity Search on Commodity Hardware

Vector database management systems support semantic search, recommendation, and retrieval-augmented generation, but many available deployments assume cloud infrastructure, specialist accelerators, or server-scale memory. This creates a practical problem for students, researchers, and small development teams who need re...

Fault-Tolerant Task Scheduling in Multicore Systems Using Hybrid Metaheuristic Algorithms

The experimental findings indicate that the combined strategy achieves shorter execution times, better scalability as workload increases, and a noticeable reduction in task failure rates, suggesting that integrating evolutionary and swarm-based optimization mechanisms can provide a practical and robust solution for imp...

Energy-Aware Task Scheduling using Grasshopper Optimisation Algorithm

Efficient energy scheduling in heterogeneous computing environments is a critical challenge, as task allocation decisions directly affect both energy consumption and execution performance. This work presents an energy aware scheduling framework based on a discretized grasshopper optimization algorithm (GOA), designed t...
