SemanticHPC: Semantics-Aware, Hardware-Conscious Workflows for Distributed AI Training on HPC Architectures
SemanticHPC addresses key bottlenecks in large-scale AI training on HPC: the semantic quality of training data and hardware-aware optimization. It integrates ontology/RDF-based semantic preprocessing with distributed AI training frameworks (Horovod/PyTorch DDP) and HPC-specific optimizations (NUMA pinning, GPU P2P, network tuning). Experimental evaluation on Open Images V7 (1-8 nodes, 4-32 GPUs) shows SemanticHPC improves validation accuracy by 3.5-4.4 absolute percentage points, with end-to-end overhead below 8% and strong scaling efficiency above 79%. The framework emphasizes a unified workflow, treating semantics as an integral part of the training pipeline rather than an isolated preprocessing step, demonstrating its potential for more effective and efficient large-scale AI on HPC systems.

Impact on Convergence and Resource Usage
SemanticHPC's richer, ontology-informed batches lead to more stable gradient updates, reducing synchronization rounds and training variance. While semantic preprocessing introduces CPU-side work and memory overhead (in-memory RDF graphs), this is offset by fewer training iterations to reach target accuracy. GPU utilization remained above 90%, CPU above 70%, confirming no major bottlenecks for the evaluated medium-sized workload. However, for significantly larger datasets, distributed SPARQL engines and on-disk indices may be needed to mitigate memory and processing limits.

Your Path to SemanticHPC Implementation
We guide you through a structured, phased approach to integrate semantic-aware AI training into your HPC environment.
Phase 1: Discovery & Ontology Design
Collaborative workshops to understand your existing data, define domain ontology, and identify key semantic features for enrichment. Establish performance baselines.
Phase 2: Semantic Preprocessing Integration
Develop and integrate RDF/OWL-based semantic preprocessing layer. Implement SPARQL rules for validation and enrichment. Setup initial semantic-aware dataloaders.
Phase 3: HPC Optimization & Training Loop Adaptation
Configure hardware-aware optimizations (NUMA pinning, GPU affinity, interconnect tuning). Adapt distributed AI training (DDP/Horovod) to leverage semantic metadata.
Phase 4: Validation & Scaling
Conduct rigorous testing and validation of the integrated workflow on increasing node counts. Benchmark performance, accuracy, and scaling efficiency against targets. Refine for production deployment.
