Speeding Up Terf, Squeak, Pharo and Croquet with a fast open-source Smalltalk VM. This is a blog about a project to build a fast open source Smalltalk VM for Terf. This is the book I never read. These are the words I never said. This is the path I’ll never tread. These are the dreams I’ll dream instead. This is the joy that’s seldom spread. These are the tears…. The tears we shed. This is the fear. This is the dread. These are the contents of my head. From “Why” by Annie Lennox. Send article as PDF.

Speeding Up Terf, Squeak, Pharo and Croquet with a fast open-source Smalltalk VM. Cog is an evolving system. Some projects are being worked on, some are as yet just dreams. We’re interested in collaborators 😉 This page may help you determine where you can help. Spur is a new memory manager whose core is a more efficient object representation that has a single header format for both 64-bit and 32-bit implementations. 8211; image segment interoperability between Spur 32-bit and 64-bit versions and between...

Speeding Up Terf, Squeak, Pharo and Croquet with a fast open-source Smalltalk VM. Building a Cog Development Image. The Cog VM source is in a Squeak Smalltalk Monticello. Package at http:/ source.squeak.org/. Load the newest version of VMMaker.oscog, e.g. VMMaker.oscog-eem.1893 (*). Building the image manually is tedious. Fortunately an automated build in Squeak 5.0 is provided in the image subdirectory of http:/ www.github.com/OpenSmalltalk/opensmalltalk-vm. This almost works perfectly; but…. The VMMake...

Speeding Up Terf, Squeak, Pharo and Croquet with a fast open-source Smalltalk VM. I’m a loooong-time Smalltalk VM implementor and systems programmer having written my first VM in 1983. I was lucky enough to work on Peter Deutsch’s. HPS VM for VisualWorks. Throughout the 90’s and early 2000’s and essentially double its speed (mostly by adding polymorphic inline caches. And rearchitecting its mapping of contexts to stacks. Team, and then went to Qwaq (now 3DICC. In helping companies exploit Pharo and Cog.

Speeding Up Terf, Squeak, Pharo and Croquet with a fast open-source Smalltalk VM. Cog is a virtual machine designed for Smalltalk. And other similar dynamic languages. Cog extends the Squeak virtual machine. Adding a stack-to-register-mapping just-in-time compiler, aggressive in-line message cacheing. And effective optimization of Smalltalk’s first-class activation records. Cog is the virtual machine underlying 3D ICC’s. Cog is also the development VM for Gilad Bracha’s Newspeak. Cog currently has back e...

Speeding Up Terf, Squeak, Pharo and Croquet with a fast open-source Smalltalk VM. Primitives and the Partial Read Barrier. If you’ve read my post on the partial read barrier. Strokes of genius; not as all pervasive or influential as BitBlt. But every bit as beautiful. Object methods for accessing. The primitive operation is signified by. Primitives either succeed and return a result, or fail without side-effects. Self systemNavigation browseAllSelect: [:m m primitive = 105]. Array methods for accessing.
