Desirable Previous Knowledge

An introductory module on basic computer architecture, and good programming skills in C/C++.

Lectures Outline (4 credit points)

  • Review of computer architecture basics - measuring performance, benchmarks, five-stage RISC pipeline, caches
  • GPU basics - evolution of GPU computing, a high-level overview of a GPU architecture
  • GPU programming with CUDA - program structure, CUDA threads organization, warp/thread-block scheduling
  • GPU (micro) architecture - streaming multiprocessors, single instruction multiple threads (SIMT) core design, tensor/RT cores, mixed-precision support
  • GPU memory hierarchy - banked register file and operand collectors, shared memory, GPU caches (differences w.r.t. CPU caches), global memory
  • Branch and memory divergence - branch handling, stack-based reconvergence, memory coalescing, coalescer design
  • Barriers and synchronization
  • Temporal and spatial locality exploitation challenges in GPU caches
  • Global memory- high throughput requirements, GDDR/HBM, memory bandwidth optimization techniques
  • GPU research issues - performance bottlenecks, GPU power modeling, high-power consumption/energy efficiency, GPU security
  • Application case study - deep learning
  • Cycle accurate simulators for GPUs

Semester-long Problem-based Project (2 credit points)

The learning in the lectures will be augmented by a semester-long problem-based project.

Please find below a brief outline of the plan for the problem-based project:

  • Several topics related to GPU architecture will be proposed (Week 2)
  • Initial discussion and group formation (Week 3)
  • Topic finalization (week 4)
  • Weekly meetings for problems and progress discussion (Week 5 - 15)
  • Work in groups possible (2 – 4 students depending upon total students)

Course Evaluation

  • Project + 30 minutes oral exam
