Using User Mode Concurrency Groups vs Futexes in Unikernels

In this video we learn about UMCG (user mode concurrency groups) and how they compare to futexes and condition variables.
UMCG is a user-space scheduling implementation that is a part of Google's Fibers but has not made it into the Linux mainline.
We show how UMCG operates and show how you might be able to write ultra highly scalable software with it.
