Are you > interested in doing that? ok, good. I understand. I'm doing a similar project for java, so I won't be able to contribute directly to your effort directly at this point. Of course, it is "a little" more convenient to rewrite CL code into CPS, than it is to rewrite java byte-code. :( --Sriram.

[erlisp-devel] coroutine revival paper
by Aurélien Campéas 28 Jun '05

28 Jun '05

In LTU today, this paper could be of interest for the erlisp bibliography : "Revisiting coroutines" ftp://ftp.inf.puc-rio.br/pub/docs/techreports/04_15_moura.pdf is a nice read (and I really like the notion of coroutines, but that's just me). Have a nice day, Aurélien.

[erlisp-devel] some thoughts ...
by Aurélien Campéas 27 Jun '05

Hello Dirk & all, a) I have quickly skimmed over the current source and it seems that the important functionality of process linking is missing, isn't it ? b) I've also just read your "mop" section of the roadmap (section 2), where you want to investigate other avenues for parallelism than Erlang's one. I suggest reading what's made available by Mozart/Oz should give you most-important ideas about that. Erlang's concurrency is only one possibility in Oz, actually one of the more complex and powerful, but there is a whole scale of ways to go concurrent worth studying there. FYI, the Oz book is available there : http://www.ulb.ac.be/di/rwuyts/INFO020_2003/vanRoyHaridi2003-book.pdf It seems to me that wrt Oz, the parallel with the MOP is only superficial. On the other hand, I know one thing called "Agent-Group-Role" developped at lirmm which really looks like a mop for multi-agent systems (whatever that means, in fact agent there has to be seen as concurrent objects). You can have a first look at this : http://www.ualr.edu/kxaydin/Agents/From%20Agents%20to% 20Organizations.pdf I really had no time to allot to seriously playing with it but I intent to someday ... :) Cheers, Aurélien.

[erlisp-devel] Lightweight processes

Hello, I'd like to find out in some more detail how you intend to solve the lightweight process problem (or have you solved it already?). As far as I can see, an erlisp process is mapped directly to a SBCL thread, which in turn is a wrapper for an OS thread. This is exactly what erlang tries to get away from and what the erlang VM is geared to do differently. --Sriram.

[erlisp-devel] Project goals
by Ivan Boldyrev 24 Jun '05

24 Jun '05

Hi, Dirk! I have some questions on project goals. 1. Are you going to create something portable or SBCL/something else only? 2. Are you going to rely on some communication library such as PVM/MPI or something completely independent? 3. Do you have some plan or just experimenting / imitating Erlang? P.S. I am interested in parallel computation in Common Lisp. I have created UFFI bindings for PVM library. Though I do not remember exact URL of the project :) -- Ivan Boldyrev

[erlisp-devel] Now on GMANE.
by Dirk Gerrits 23 Jun '05

If all goes well, this e-mail should trigger the creation of the gmane.lisp.erlisp.devel newsgroup on news.gmane.org. The newsgroup is a bi-directional interface to the mailing list, so e-mails sent to either one will show up on both. Newsgroup lovers rejoice! ;) Kind regards, Dirk Gerrits
