GPGPU Simulator Engineer

About the role

Design, develop, and maintain full-system or module-level functional/performance simulators for GPGPUs (e.g., based on GEM5, QEMU, or in-house frameworks). Model core GPGPU components, including compute units (SIMD Cores, Tensor Cores), on-chip memory subsystems, on-chip interconnects, and schedulers. Enable execution and debugging of workloads using standard GPGPU programming models (e.g., CUDA, OpenCL) within the simulation environment.

Key responsibilities

• Design, develop, and maintain full-system or module-level functional/performance simulators for GPGPUs (e.g., based on GEM5, QEMU, or in-house frameworks)
• Model core GPGPU components, including compute units (SIMD Cores, Tensor Cores), on-chip memory subsystems, on-chip interconnects, and schedulers
• Enable execution and debugging of workloads using standard GPGPU programming models (e.g., CUDA, OpenCL) within the simulation environment
• Work closely with architecture, compiler, driver, and algorithm teams to validate new architectural features, assess performance bottlenecks, and guide hardware design decisions
• Optimize simulator performance using techniques such as dynamic binary translation, parallel simulation, and approximate modeling to enhance simulation throughput
• Develop and maintain automated regression testing and benchmark suites to ensure simulator accuracy, reliability, and stability
• Create and maintain comprehensive technical documentation for internal and external users

About you
