📋 Description

• Evaluate and enhance the performance of CPU clusters, focusing on cache hierarchies, interconnects, coherence, and memory access patterns.

• Develop and utilize performance models and simulation frameworks like Gem5 or similar tools.

• Analyze real-world workloads to pinpoint bottlenecks related to cache misses, coherence traffic, memory bandwidth, latency, contention, and core-to-core communication.

• Lead studies on architectural trade-offs balancing performance, scalability, bandwidth, latency, power consumption, and implementation complexity.

• Work collaboratively with architects specializing in CPU, cache, interconnect, memory, software, compilers, RTL, and system design.

• Convert performance analyses into specific architectural and design recommendations.

• Design, model, and optimize multi-core CPU clusters from initial performance exploration to implementation and silicon.

⛳️ Requirements

• Solid understanding of CPU microarchitecture and performance principles.

• Comprehension of the interactions between cores, caches, interconnects, and memory systems.

• Experience or proficiency in modeling, simulation, and workload analysis techniques.

• Capability to identify cluster-level performance bottlenecks and scaling issues.

• Familiarity with latency, bandwidth, quality of service, utilization, and scalability concepts.

• Ability to translate performance data into architectural suggestions.

• Excellent communication and collaboration skills across different functional teams.

• Knowledge of cache hierarchies, interconnects, coherence, and memory access dynamics.

• Experience with performance models and simulation environments such as Gem5 or equivalent.

• Understanding of cache misses, coherence traffic, memory bandwidth, latency, contention, and core-to-core interactions.

• Eligibility for accessing U.S. export-controlled technology; employment may depend on citizenship/permanent residency status or obtaining prior license approval.
