Job description

We are seeking a highly motivated performance engineer to join our workload modelling and simulation team to work on improving and optimization of performance for current and future Huawei's server and datacentre products. As performance optimization and simulation engineer you will work on investigating of performance bottlenecks of applications like databases, distributed storages, engines for large-scale data analytics, as well as AI-specific applications to improve their overall performance by proposing new custom instructions or CPU instruction set extensions and proving possible performance improvement through simulation.

Responsibilities

• Performance analysis of applications of interest to propose new instructions and ISA extensions.
• Reworking and optimization of critical parts of applications to support new ISA.
• Implementation of proposed new instructions or uArch tweaks in performance simulator for evaluation of possible performance benefits.
• Deep understanding of modern CPU architectures.

• Knowledge and experience of using latest Aarch64 or X86 instruction sets.
• Background in performance analysis, profiling and workload characterization.
• Excellent collaboration and interpersonal skills

• Experience in developing and using performance simulators like GEM5 (O3 model), Sniper or others is a big plus.
• Experience in developing and using dynamic binary instrumentation infrastructures like QEMU or DynamoRIO or x86 PIN is a plus.
• Knowledge of NPU/GPU architecture
• Experience in simulator development for NPU/GPU
• Experience in implementing instructions in the ARM/x86 architecture is preferred.

Founded in 1987, Huawei is a leading global provider of information and communications technology (ICT) infrastructure and smart devices. We have 207,000 employees and operate in over 170 countries and regions, serving more than three billion people around the world.
