Sr Performance Control Architect- Platform Architecture

Santa Clara Valley (Cupertino), California, United States
Hardware

Summary

Posted: Oct 24, 2018
Weekly Hours: 40
Role Number: 200002931
Platform Architecture is looking for a Sr Performance Control Architect to measure, analyze and control the relationship between power and performance in Apple’s most advanced systems on a chip. In this position, you will study the execution of iOS workloads on Apple silicon and demonstrate that understanding to influence the design of both hardware and software. You will design and conduct power/performance/thermal experiments, create instrumentation and data visualizations, contribute to Apple’s culture of debate, specify new SoC features, model innovative performance control algorithms, and help develop the software that controls the performance of every application workload on hundreds of millions of iOS devices around the world.

Key Qualifications

  • Research experience investigating execution efficiency in computing systems, particularly on real silicon
  • Comprehensive statistics and quantitative analysis skills
  • Understanding of the techniques used to manage power delivery and thermal limits in modern systems
  • Hands-on experience with hardware instrumentation, including power measurement and performance counters
  • Knowledge of computer architecture, including the relationships between CPUs, GPUs, other compute clusters and memory hierarchy
  • Userland software (e.g., application, simulation, test harness, data analysis) development experience in environments such as C, C++, Objective-C, Swift, Python, Perl or MATLAB is critical
  • Kernel software development experience in C or C++ is desirable

Description

As a Sr Performance Control Architect, your job responsibilities will include: Design and conduct experiments to characterize execution efficiency and the effects of physical constraints such as temperature or current limits Use excellent empirical methodology to illuminate power–performance trade-offs Collaborate with and influence a broad multi-functional audience spanning processor architecture, silicon engineering, system integration, OS development and application software performance evaluation Research and find opportunities to improve the measurement and control capabilities of Apple SoCs Invent new performance control concepts and carry them through modeling, prototyping, production implementation and tuning

Education & Experience

MS/PhD in Computer Science or Electrical/Computer Engineering or equivalent
