This course aims to teach learners about achieving strong consistency in persistent memory file systems using hardware transactional memory. The course covers topics such as performance trade-offs, hardware transactional memory, crash consistency mechanisms, and the HOP mechanism for achieving strong consistency. The teaching method involves a presentation of research findings and performance evaluations. This course is intended for individuals interested in file system designs, persistent memory, and achieving high performance with strong consistency in data storage systems.
