Hello lists,
(see http://en.wikipedia.org/wiki/Cell_division for explanation what mitosis is ;)
i just finished another torturing session in slang land, and finally made some of it working :)
I added a two new primitives, which aimed towards creating a new heap by cloning a designated set of objects from existing one. A first primitive is helps you to create a closed graph by reporting a set of objects which is referenced by objects in provided array, but not included in this array itself.
A second primitive is actually serves for creating a baby heap. I takes two array arguments: objects graph, and replacements (or substitutions).
The rules is simple: each object included in first array, should have references to objects which included in this array as well i.e. (objects identityIncludes: (objects at: x) someIvar ) == true
or if its not , then it can be found in a substitutions array. A substitutions array is a flat array of pairs oop -> index, where oop can be any oop, and index is a smallint index of item in objects array. Upon creation of new heap, all refs to oops in 'substitutions' array will be replaced by refs from 'objects' array by taking corresponding index.
Both array arguments should contain oops only (except from indexes in substitutions array) , should not contain duplicates and their intersection should be empty , i.e. (objects intersection: substitutions) isEmpty == true.
All of these rules actually serving to ensure that newly created object memory will form a fully closed graph (hence its oops can be cloned to a standalone object memory).
There are also, an initial example how to create a 'baby' object memory load http://www.squeaksource.com/HydraVM/HydraVM-sig.17.mcz
and do:
HydraClone new cloneIdleProcess
Of course you will need new VM. Sorry, i didn't published an update of sources yet. I can only give you a prebuilt one. Once i had a write access to ftp.squeak.org/HydraVM but i forgot credentials/key to it. (if Box Admins help me with this, i will upload it there). Or, you can write me in private and i will send you binaries.
P.S. I want to give a credit to Klaus D. Witzel who helped me to finish these new features, and inspired to do it :)
Update. you can download binaries from here ftp://ftp.squeak.org/HydraVM/latest_builds/win32/HydraVM-bin-22.02.2009.zip

Let me add 2-3 bits: first we also have to thank Alexandre "Alex" Bergel and Guillermo "Guille" Adrián Molina for discussing with us earlier approaches to running Smalltalk on n-core CPUs in parallel.
2nd: what expression (HydraClone new cloneIdleProcess) does for you, is it runs the computational task which is described by the corresponding object subgraph, in a *new* native thread (with own heap and instance of HydraVM). Therefore, on your n-core CPU you can expect that computation is spread among the cores. The #cloneIdleProcess example does just what its name says: it runs Smalltalk's idle process ;) as proof of concept.
You Smalltalkers may have other Smalltalk processes that you want to run in parallel on their own native thread; let us know how we can help you with that.
And in case you need communication between two or more .images, Hydra comes with its channel facility.

Well I have this web framework thingy where each http connection runs in it's own process. Request processing is quite fast, sometimes below a millisecond. There is potentially a lot sharing going on between those connections for configuration, sessions, continuations and stuff.

Yeah we thought about that, after exchanging some Qs+As with Lukas (and/or you?) during last Camp Smalltalk, for the general case for Hydra.
Several things are competing for attention/resolution/prototypical work:
1) some [accepted] Socket (and its OS dependent bits) can "belong" only to one native thread (= independent .image) in Hydra. Is this compatible with your web framework's requirements.
2) it must be possible for one native thread to accept a Socket, for another one to read/write it and get rid of it (and of its OS dependent bits). This is not a problem for us at the Smalltalk language/heap level but, until now I did't find an OS guy who said "this works, with guarantee, on these XYZ platforms".
3) when your web framework+app depends on a database "whatsoever", how is this to be shared (if sharing is really needed) between multiple native threads.
4) put yours here

Yepp, if you interpret database in a more general sense (a bunch of objects). There is also the question of how coordination happens between multiple images especially on this shared data.

Yup. And the price tag is a) transfer "task description" to worker thread and b) transfer "result string" back in full or in part(s). And when using Hydra channels for transfer, add c) c-alloc of strings-to-be-transported.

Right. Looks like a topic for the next Camp Smalltalk, with hands-on.

Sure, it'd probably be best if you could attend a Squeak Stammtisch or Seaside Sprint (all these S) so we could discuss it a bit further.

I whish there be something like Cobalt[0] ready for primetime, so that every Friday night there be Smalltalk Friday night, nation-wide as with other local holidays and around the globe. Of course there also be (all these S) events but entrance only allowed for Smalltalkers bringing their family members/friends for pro-actively managing the future ;)
Do you happen to know of an (all these S) event planned at/around May?
Cheers Philippe
Hi Klaus--
I wish there were something like Cobalt ready for primetime, so that every Friday night could be Smalltalk Friday night, nationwide as with other local holidays and around the globe.
It seems like they've made a lot of progress recently. What do you think the 2009-02-10 release needs in order to make your idea doable?

Right, {been there. done it}.
What do you think the 2009-02-10 release needs in order to make your idea doable?
- usable "installable" for non-platform experts
- tools have to work on the 2+1 platforms (no idea, I myself cannot compare)
- create+provide community-support-contents:
-1 "certify" users so that they can *really* participate -1 and not run away "doesn't work for me/my PC, is crap"
-2 a reception for "where's my party"
-3 host many parties (Kernel, Framework(s), App(s), etc)
The above is *not* much, and I believe Cobalt is getting hotter -- we'll have a Cobalt-hot summer :)

Perhaps naively, I simply downloaded the binaries and used them to open a 3.10 dev image, which seemed to work fine, FreeType and all...
So...from the helpful doits, it seems that you prepare a second image that carries out the native processes for you? Or can you run several native threads within the current image?
Very interesting...and what is most impressive is that someone relatively unsophisticated like me could just open an image with the new VM, load the HydraVM package from Squeaksource and get have HydraVM isHydra return true!
A short example of creating a "lengthy process" running in it's own thread would be great...you know, something that just counts for a really long time or something.
This is very interesting!

Yes, "classic" Hydra loads the second .image from file and mitosis Hydra populates (the second) an empty .image from am arrayOfObjects passed in.
Or can you run several native threads within the current image?
*run* within the current .image: No. *clone* from within the current .image: Yes.

Like (123456 factorial) ? you want to see one of the cores running at 100% (instead of the idle loop); message understood :)

Ok...this is just, well, fun, but I can't quite figure out how to get a second image loaded with the #doIt channel "working." I figure it's because I don't have the image I created it from set up right? All I did was go down the line of in the Helpful doits workspace:

Yep.. in 3.10 this not working.. It looks like there are some crap in image startup method. As a workaround, you can register the #doIt channel in your base image:
HydraVM registerDoItChannel. and only then do HydraVM saveAsHeadlessImage: 'test.image'
should work ok.

Okay, here's updated VM
ftp://ftp.squeak.org/HydraVM/latest_builds/win32/HydraVM-bin-27.02.2009.zip
bug with channels are now fixed (in fact it is bug with code generator :))
Everything should work ok now i.e. channels + heap cloning.
Also, i uploaded the updated VMMaker:
http://www.squeaksource.com/HydraVM/VMMaker-sig.85
and platform sources:
http://squeakvm.org/svn/squeak/branches/HydraVM
I got all the way up to 10000 factorial! (Stressing, no doubt, the amount of data flowing through the channels...)
(Not happy at 11000...!)
Fun stuff...

Also, i uploaded the updated VMMaker:
This loads into a Squeak3.10.2-7179-basic.image, *after* resolving FFIConstants, KlattResonatorIndices by hand (Monticello does not know what shared classes are).
and platform sources:
This compiles fine with the mingw tool chain.
Thanks for the good work Igor !

Hydra wasn't ported on linux yet. Initially i created a Win32 VM. Then Matthew Fulmer started linux port, but it wasn't finished. There is also a Mac port, made by John M McIntosh , and he reported that he were able to run it. But its not complete - a lot of plugins need additional porting.

Last spring I ported Hyrda to the macintosh carbon VM, it ran, but there were problems with Sockets, plus it was a moving target, then Igor took some time off, so I shelved further effort.
At thistime I don't see really building a new one (unless some has funding). Did I mention it's a moving target?
However out of it I did separate out all the platform support API from what VMMaker generates and requires. That effort then was folded into the iPhone VM and documentation on the isqueak.org site.

You are right, it is highly experimental, and initially was developed as a proof of concept.

Yes, except the unsent messages and unreferenced variables, they can be nil'ed using the substitution array. Example: many fields of Class(es) are for use by the IDE only, just nil'em.
Or is there a way objects/code can be loaded on demand like (If I understand this correctly) Craig's Spoon system does?
No. Spoon's dynamicity is not part of Hydra mitosis (and in order to add it, Spoon must be added).
Would it be possibel to save the so created (minimal) image to reuse it later?
Yes: do transfer the corresponding method then put it [the method] to work. "classic" Hydra can then load+run the saved .image as usual.
And if that .image also contains sufficient GUI,etc objects, even the non-Hydra VM can load+run it and render it for your use.

Hello lists,
(see http://en.wikipedia.org/wiki/Cell_division for explanation what mitosis is ;)
i just finished another torturing session in slang land, and finally made some of it working :)
I added a two new primitives, which aimed towards creating a new heap by cloning a designated set of objects from existing one. A first primitive is helps you to create a closed graph by reporting a set of objects which is referenced by objects in provided array, but not included in this array itself.
A second primitive is actually serves for creating a baby heap. I takes two array arguments: objects graph, and replacements (or substitutions).
The rules is simple: each object included in first array, should have references to objects which included in this array as well i.e. (objects identityIncludes: (objects at: x) someIvar ) == true
or if its not , then it can be found in a substitutions array. A substitutions array is a flat array of pairs oop -> index, where oop can be any oop, and index is a smallint index of item in objects array. Upon creation of new heap, all refs to oops in 'substitutions' array will be replaced by refs from 'objects' array by taking corresponding index.
Both array arguments should contain oops only (except from indexes in substitutions array) , should not contain duplicates and their intersection should be empty , i.e. (objects intersection: substitutions) isEmpty == true.
All of these rules actually serving to ensure that newly created object memory will form a fully closed graph (hence its oops can be cloned to a standalone object memory).
There are also, an initial example how to create a 'baby' object memory load http://www.squeaksource.com/HydraVM/HydraVM-sig.17.mcz
and do:
HydraClone new cloneIdleProcess
Of course you will need new VM. Sorry, i didn't published an update of sources yet. I can only give you a prebuilt one. Once i had a write access to ftp.squeak.org/HydraVM but i forgot credentials/key to it. (if Box Admins help me with this, i will upload it there). Or, you can write me in private and i will send you binaries.
P.S. I want to give a credit to Klaus D. Witzel who helped me to finish these new features, and inspired to do it :)

In principle: Yes.
Hydra mitosis tranfers all objects required by contractual obligation with the VM (special objects array, methods, context, process, scheduler, method dictionaries, classes, language level constants, etc).
This all has to be closed under #pointsTo: for each fixed/indexed field in transit.
And it populates an empty instance of ObjectMemory.

Yes, this is why an example object memory (HydraClone new cloneIdleProcess) having 650 objects. I had to build a correct special objects array, which obliged to include: 256 character objects 32 special selectors and 80 objects in quiescentProcessLists.
This all has to be closed under #pointsTo: for each fixed/indexed field in transit.
