Science, Art, Voodoo: Using and Developing The Graal Compiler

The 2020 Graal Workshop was held at CGO in San Diego, CA on 22nd February.

Checkout the presentations available on Twitter #graalcgo2020!

Topics for discussion included making effective use of the Graal compiler, performance evaluations and opportunities with Graal on benchmarks and applications, developing new features and optimizations in Graal, creative and novel uses of the Graal infrastructure and growing the Graal CE open source community.


9:00 AM - Welcome

9:15 AM - Keynote: Tom Rodriguez (Oracle Labs)

Title: Graal as a native JIT in GraalVM Abstract: This talk will discuss the design and implementation of libgraal, the Graal and Truffle JIT compiled into a static library using Native Image that is used as the default JIT in GraalVM. It will describe the challenges of interfacing libgraal with HotSpot, the way native compilation mode differs from the pure Java compilation mode and the various ways Substrate technologies are used within the library itself. Bio: Tom Rodriguez started worked on the JDK around 1.1 and worked on HotSpot starting in 1.4, primarily on the client and server compilers. For the last six years he’s been a member of the Graal compiler team and was the primary implementor of libgraal.
