Mark N
CPU Performance Architect at Arm
Austin, Texas, United States
Summary
👤
Senior🎓
Top SchoolMark N is a CPU performance architect with 26 years of experience designing and validating pre-silicon performance models for high-performance processors, currently working on Arm’s big-core pre-silicon performance team in Austin. His career spans kernel and simulator development at IBM—where he led the mambo functional simulator project and worked on POWER processor tooling—through architecture and hybrid execution-driven simulation for Samsung’s custom ARM cores. He combines deep low-level C and hardware-interfacing skills (evidenced by contributions to the OpenHMD driver for VR headsets) with practical systems-level insight from HPC, Linux kernel, and firmware stacks. Mark is comfortable bridging research and product delivery, having integrated functional models into cycle-accurate full-system simulators to run real software stacks well before silicon exists. He also brings an unusual mix of hands-on review experience from consumer motherboard benchmarking, giving him a practical perspective on performance and power trade-offs.
