In this project, we investigated the redesign and usage of io_uring kernel thread poller in the setting of low-latency (10 usec) Optane SSD.

My contribution:

  • Framed the problem of co-design CPU scheduler and IO poller, discussed implementation and evaluation ideas.
  • Owned microbenchmark experiments (in Bash and Python).
  • Ported io_uring based IO moduler from FIO to KVell key-value store (in C).
  • Added microburst workloads to FIO (in C), among other feature enhancements and bug fixes.
