Research Assistant @ Texas Tech University, Lubbock, TX (USA)

Aug 2022 - Present

Department of Computer Science.

Secure High-Performance Computing Architectures Project:

• Adapting a parallel programming runtime to experimental OS and architectures.
• Architecting an address extension technique for secure distributed memory architectures, enhancing memory protection capabilities.
• Collaborating in the design of a global address space extension on RISC-V and ARM architectures to enable memory protections on scalable computing centers.

Energy-Efficient GPU Computing Project:

• Optimized GPU performance and energy efficiency in HPC systems using DVFS, achieving up to 30% energy savings with minimal (~5%) performance loss.
• Implemented analytical and deep learning-based models, integrating workload-specific energy-performance trade-offs for real-world HPC and ML workloads.
• Demonstrated model portability across NVIDIA (A100, V100, P100) and AMD (MI100, MI210) GPUs using CUDA, DCGM, ROCm, Python, and DNNs.
