Thanks Mikael.

Is that available in 4.6.6 or git HEAD? Is there any example code of this? Is it done with C base code spawning the different instances in different threads?

Search the ML. Maybe Marc posted it here as a patch.

Yes, that next step is what would greatly improve the situation regarding multithreading :)

Yes!

Best regards,

Álvaro

Alvaro,

There's two levels to this. There is the support to run several GVM instances - as in separate Gambits with completely separate heaps - within one OS process, since this spring.

The SMP support - as in, >=1 OS threads utilized by the same one GVM and heap, is the next step. This will be great when it comes out and I completely share your interest in knowing about the current plans for it.

Best regards, Mikael

Hi!

Ok, I know this has been asked before.

What are the perspectives of Gambit supporting native threading?

I remember that Marc made some tests to see how much the code performance would be affected due to global variables access indirection. However, native threading, at least basic facilities, are a must for programming languagues nowadays. Termite, IPC or network can't be really used for things like games.

I think this is a hard problem, of course, and if I would be of any help I'd like to, although I don't have much experience implementing compilers myself.

Thanks,

Álvaro

Thanks a lot for your reply, and especially, for all the effort put into constantly improving Gambit.

I am working on multithreading support and hope to have it working by the end of the summer. A summer student will be helping out on this project.
