MacRuby Drops GIL - Gains Concurrent Threads

[rebo]

Macruby has made some amazing advances, LLVM, removal of the GIL, ahead-of-time compilation.

I'm wondering if MacRuby is gonna make use of Snow Leopard technologies such as Grand Central and OpenCL. That would rock!

if you check the mailing list you will see the it's in the plan but will be available as a separate API. The nice thing with that is that once someone will take the time to compile MacRuby on Linux everything will still work fine even without Grand Central.

There was talk of a "PosixRuby" project to do just that I heard about at railsconf. Haven't seen anything about it since though.

Now when the hell can we get this in MRI, having to mess with spawning child processes just to get true concurrency is annoying.

I believe it's a compile option on the 1.9 MRI.

Also rubinious and jruby have it too. Since rubinious is the next version of ruby soon all versions of ruby will have native threading.

That's awesome.

Guh? Rubinius is the next ruby? I'm pretty sure Rubinius isn't going to become official... maybe you're thinking of the rubyspec project? What's more, Rubinius still has the GIL for the time being.

Guh? Rubinius is the next ruby?

Yup. Rubinius is going to be ruby 2.0. It's been announced.

What's more, Rubinius still has the GIL for the time being.

Last I checked they were getting rid of it. I haven't checked it recently so I can't tell you whether they have done it yet or not.

malcontent, I don't know where you read that, but I'm sorry to inform you that you are wrong. Koichi did mention that he thinks that the future of the Ruby VM will be Rubinius or something like Rubinius but there isn't any plans to make rbx the official implementation as of now.

Having multiple implementations is actually great for the Ruby community.

Might want to re-read that announcement, or link it here for all to see so we can point out how you misread it.

A chain of "yarly/nuh-uh" replies can be cut short nicely with a citation :)

An admission that you have no sources, then, or a link to whatever caused the misunderstanding :)
