Memory Systems for the Heterogeneous Era
Aamer Jaleel, NVIDIA


Emerging high performance computing systems consist of multiple latency optimized processors (e.g., CPUs) and throughput optimized processors (e.g. GPUs) interconnected using a high performance network. The performance of such heterogeneous systems is directly dependent on the processor memory hierarchy. This course covers the trade-offs when designing a high performing memory hierarchy for CPUs, GPUs, and heterogeneous systems consisting of multiple CPUs and GPUs. We will show that different design constraints yield different solutions when designing the memory hierarchy. The lectures will cover fundamental design concepts and state-of-the-art research in virtual memory, cache hierarchy, and main memory systems.

The course will also include personal experiences on commercializing research ideas and also include discussions topics on areas for continued research.
