  • Develop and refine a Performance Modeling infrastructure and near cycle accurate models
  • Define (and develop as necessary) applications, benchmarks, and micro-benchmarks on which to measure performance
  • Analyze and verify important performance characteristics at multiple levels of simulation, as well as with prototyping platforms and silicon. Track results over time and quickly identify unexpected regressions
  • Work with Core and Noncore Architects and the RTL Design team to identify performance opportunities and identify approaches to address them. Help specify performance monitoring hardware support

Collaborate with our Software team on:

  1. Characterization and optimization of key software libraries and middle-ware (e.g. JVM)
  2. Compiler/toolchain optimization/tuning guidelines for our microarchitecture
  3. Application-level workload characterization/optimization

Qualifications Required:

  • 8+ years industry experience with responsibility for either microarchitecture/design or a combination of performance modeling, analysis, validation, and correlation for high performance CPU or GPU, memory subsystem, or related system-level designs
  • Strong domain knowledge of state-of-the-art computer architecture concepts
  • Ability to work independently and across geographies, with a passion to develop the best possible products
  • Bachelors or Masters degree in a related engineering field

Skills Desired:

  • C/C++/System-C modeling of near cycle accurate simulators
  • Industry experience with CPU microarchitecture (e.g. ISAs including: x86, ARM, SPARC, MIPS, RISC-V, POWER) and/or coherent caching systems
  • Working knowledge of compiler technology and optimization techniques
  • Verilog/SystemVerilog development experience
  • Experience in compiled and/or interpreted (Python, perl) languages, especially with respect to processing large, complex data sets and extracting meaningful information
