TruffleSqueak 24.2.2 based on @GraalVM JDK 24.0.2 is out! 🐭🎉. Now including support for ephemerons and infinite call stacks, significantly fast becomeForward: and allInstance, and more!. ➡️

Thanks to a community contribution, @TruffleSqueak now has preliminary support for ephemerons and can run the latest Cuis Smalltalk 7.3! 🥳.

TruffleSqueak 24.1.2 based on @GraalVM JDK 23.0.2 is out! 🐭🎉. Now featuring significantly faster image loading, new extensions for language interoperability, and more!. ➡️

RT @fniephaus: Our new DSL for generating bytecode interpreters just got merged! 🥳. Once applied, this is going to improve interpreter perf….

Also, CompiledCode objects (methods and blocks) are now more memory efficient:. - - -

Inspired by the submissions for @gunnarmorling's #1brc, we applied two new optimizations to speed up @TruffleSqueak's startup:. - Use custom map instead of java.util.HashMap (.- Use memory-mapped file to load image (.

TruffleSqueak 24.0.2 based on @GraalVM JDK 22.0.2 is out! 🐭🚀🎉. Now featuring an InterpreterProxy implementation, Maven artifacts for embedding @SqueakSmalltalk in @Java applications, and a lot more!.

Another @TruffleSqueak release is on the horizon! 🤓.

The next release of @TruffleSqueak for Linux and Windows will ship with SqueakSSL and LocalePlugin "pre-copied". In case you are wondering about the completeness of the InterpreterProxy API, the students have also prepared a nice visualization:

Reusing a plugin from OpenSmalltalkVM is as simple as copying the corresponding shared library over into @TruffleSqueak's lib directory. Here's a demo from the students illustrating this with SqueakSSL:

Many OpenSmalltalkVM plugins, such as SqueakSSL, can now be easily reused in @TruffleSqueak, which improves compatibility significantly!. Thanks to students from @HPI_DE, TruffleSqueak now has an InterpreterProxy implementation that makes this possible:

RT @fniephaus: @TheDonRaab Here's a collection of fun @TruffleSqueak demos, talks, and publications in case anyone is interested in what ha….

TruffleSqueak 23.1.0 based on @GraalVM JDK 21 is out! 🐭🚀🎉. Now shipping new JVM standalones for all platforms, an additional native standalone for Windows, plus some important bug fixes and performance improvements!. ➡️

The performance reports for 23.0.1 are in! The AWFY benchmarks run more than 5min faster on @TruffleSqueak in JVM mode when using Oracle @GraalVM [1] compared with GraalVM Community Edition [2]. That's ~73.65% of 20.99s. [1] [2]

TruffleSqueak 23.0.1 for @GraalVM JDK17 & JDK20 is finally out! 🐭🚀🎉. Now with @SqueakSmalltalk 6.0 support, standalones built with Oracle GraalVM, support for bytecode OSR, improved memory usage, and the usual bug fixes and performance improvements!. ➡️

The standalone builds of @TruffleSqueak are now compiled with Oracle @GraalVM! 🐭🚀.This improves performance yet again and allows TruffleSqueak to use the G1 garbage collector on Linux/x64. Example build: Commit:

RT @fbrasisil: @paul_snively Btw, have you seen trufflesqueak yet? It’s 🤯

The next standalone builds of @TruffleSqueak will use Oracle @GraalVM to unlock all Graal compiler optimizations, the G1 garbage collector on Linux, and more performance features! 🚀.

RT @graalvm: AWT libraries are now linked dynamically by Native Image on Linux, which enables native AWT apps on JDK17+. Here's a screensho….

TruffleSqueak now uses the max stack depth of a Smalltalk method to determine the # of allocated frame slots. @GraalVM's compiler can eliminate unused slots, but the interpreter cannot. Result: reduced memory pressure and overall memory footprint! 🐭🚀. ➡️
