Top SchoolHenry Estela is a Senior HPC Cluster Engineer with 12 years of hands-on experience building and operating large-scale HPC and AI clusters, currently at NVIDIA. He combines deep systems expertise—SLURM, InfiniBand fabrics, PXE/OS provisioning, and server firmware automation—with practical software skills in MPI development, benchmarking, and Python/Bash tooling. At Intel and Accenture he managed validation labs and cloud-based clusters of thousands of nodes, wrote automation for firmware flashing and benchmarking harnesses, and solved tricky kernel, networking, and GPU performance regressions. An active contributor to low-level projects like the Intel Graphics Compiler and linux-rdma tooling, he brings both hardware-adjacent debugging chops and reproducible benchmark pipelines. Based in California, he’s not actively looking but remains engaged in optimizing HPC workflows and capacity planning for large multi-tenant environments.
