Job description

About The Role

Join Cerebras as a Performance Engineer within our innovative Runtime Team. Our groundbreaking CS-3 system, hosted by a distributed set of modern and powerful x86 machines, has set new benchmarks in high-performance ML training and inference solutions. It leverages a dinner-plate sized chip with 44GB of on-chip memory to surpass traditional hardware capabilities. This role will challenge and expand your expertise in optimizing AI applications and managing computational workloads primarily on the x86 architecture that run our Runtime driver.

Responsibilities

• Focus on CPU and memory subsystem optimizations for our Runtime software driver, enabling faster key cloud and ML training/inference workloads across modern x86 machines that form the backbone of our AI accelerator.
• Develop and enhance algorithms for efficient data movement, local data processing, job submission, and synchronization between various software and hardware components.
• Optimize our workloads using advanced CPU features like AVX instructions, prefetch mechanisms, and cache optimization techniques.
• Perform performance profiling and characterization using tools such as AMD uprof, and reduce OS level overheads.
• Influence the design of Cerebras\' next-generation AI architectures and software stack by analyzing the integration of advanced CPU features and their impact on system performance and computational efficiency.
• Engage directly with the AI and ML developer community to understand their needs and solve contemporary challenges with innovative solutions.
• Collaborate with multiple teams within Cerebras, including architecture, research, and product management, to elevate our computational platform and influence future designs.

Skills & Qualifications

• BS, MS, or PhD in Computer Science, Computer Engineering, or a related field.
• 5+ years of relevant experience in performance engineering, particularly in optimizing algorithms and software design.
• Strong proficiency in C/C++ and familiarity with Python or other scripting languages.
• Demonstrated experience with memory subsystem optimizations and system-level performance tuning.
• Experience with distributed systems is highly desirable, as it is crucial to optimizing the performance of our Runtime software across multiple x86 hosts.
• Familiarity with compiler technologies (e.g., LLVM, MLIR) and with PyTorch and other ML frameworks.

Why Join Cerebras

• Build a breakthrough AI platform beyond the constraints of the GPU.
• Publish and open source their cutting-edge AI research.
• Work on one of the fastest AI supercomputers in the world.
• Enjoy job stability with startup vitality.
• Our simple, non-corporate work culture that respects individual beliefs.
