About the Role
Apple is a place where extraordinary people gather to do their lives best work. Together we create products and experiences people once couldn't have imagined, and now, can't imagine living without.
Responsibilities
- Work with driver, compiler, and designs engineers to improve GPU performance.
- Validate functionality and quantify performance benefits of features and algorithms.
- Implement solutions in hardware and software.
- Conduct directed studies to provide solutions to performance challenges unique to mobile GPUs.
- Drive the architecture of next-generation mobile products via measurements, simulations, benchmarking, or competitive analysis.
- Debug potential GPU performance issues and fix them with design engineers.
- Conduct GPU performance contests to measure GPU performance.
- Work with software teams to develop GPU models in different sections.
- Develop tools to aid in efficient measurement, communication, and improvement of GPU performance.
Requirements
- Utilize C and Python to develop performance analysis tools and automation scripts for GPU microarchitecture evaluation.
- Experience with compiler toolchains, including analyzing instruction scheduling, register allocation, and code generation for GPU compute workloads.
- Experience with SystemVerilog or Verilog, including reading and analyzing RTL to identify and debug hardware-level performance bottlenecks.
- Experience in GPU microarchitecture analysis, including utilizing performance counters to evaluate throughput, latency, and execution unit utilization.
- Experience in memory hierarchy and NUMA architecture analysis, including cache behavior, memory bandwidth characterization, and error correction mechanisms.
- Utilize Python (Pandas, Matplotlib) and data visualization tools to build performance dashboards and report regression trends to engineering teams.
- Utilize scripting languages including Python and Shell to automate performance regression testing, benchmark execution, and results collection.
- Experience in full-stack hardware/software performance analysis, including correlating compiler output to microarchitecture execution behavior across silicon and pre-silicon environments.
