Abrar Hossain
PhD Candidate in Computer Science
The University of Toledo · expected 2027
I am a PhD candidate in Computer Science at the University of Toledo, working on autotuning, compiler optimization (MLIR), and instrumentation for high-performance computing. My earlier Master’s research focused on power- and cost-aware HPC scheduling. I have worked as an intern and visitor at NCSA and NSF NCAR, building network monitoring and community-scale IoT data systems. I serve as an NSF ACCESS Student Champion and received the SGX3 Rising Star of the Year Award (2025).
Research
I work on making high-performance systems faster, easier to optimize, and more predictable.
Autotuning & compiler optimization
I work on learning-based autotuning for compilers and HPC systems, including reinforcement learning for MLIR loop transformations (LoopRL), transfer-aware Bayesian optimization, and bandit-based tuning for edge devices (LASP). I also study autotuning techniques across the HPC stack.
Instrumentation & performance analysis
I work on performance analysis of modern accelerators, focusing on dynamic instrumentation for dataflow architectures and congestion-aware GPU warp scheduling.
Reliable performance prediction
I work on risk-controlled multi-fidelity conformal prediction to improve the reliability of performance estimates using measurements with varying costs and accuracy.
Master's research
Power- and cost-aware HPC scheduling
I worked on power-aware HPC scheduling using graph neural networks (TARDIS), electricity cost optimization across HPC centers, auction-based network resource allocation, and scalable scheduling simulation using SST.
