Philly ETE 2021 — Journey to the Centre of the JVM — Daniel Spiewak

Tags: , ,


What do you do when your quest for power leads you to implementations which are not just platform-but processor- and even architecture-version-specific in nature? How do you even start tracking down a bug in a Scala-based implementation which is not only nondeterministic, but only manifests on certain hardware?

In this talk, we will dive into the wild and ill-understood world of CPU architecture, memory models, and JVM intrinsics (all through the lens of very high-level purely functional abstractions!) as we examine the story of the most convoluted and mind-bending bug hunt of my entire career.
