Hello Friends, A trade rag blurb that I read the other day and can't find now discussed the programming language Linda. It is a language for writing network distributed programs and compiles into C, Fortrash, Modula-2, and some others. Paraphrase: "Currently programs talk to each other over the network with a sort of telephone call. Linda uses a distributed bulletin board instead, called 'tuple space'. All the subprograms on individual machines add tuples to the tuple space and pull them off whenever they like." The very superficial article implied that it's a very slick system for doing distributed programs and doing low-level communication between them. It was written by David Gelertner at Yale. Does anyone have any info on this? Is it public domain? FTP-able? How about a mail address (from usenet) to Professor Gelertner or a general postmaster/address finder at Yale? Thanks in advance, Jerry O. Merlaine Bell Technologies Fremont CA pacbell.com!belltec!jom

It does specify a particular memory model (tuple space) and set of operations on that memory that, taken together, provide support for explicit parallel/distributed programming. This model can be added to many "standard" languages (we have done so to C and Fortran, others are working on languages such as Modula-2 and Lisp) to produce a variant language (C-Linda, Fortran-Linda, etc.) that, together with a suitable run-time kernel, can support parallel and distributed programming on a wide variety of machines (ranging from Encores and Sequents to hypercubes to lans). >The very superficial article implied that it's a very slick system >for doing distributed programs and doing low-level communication between them. >It was written by David Gelertner at Yale. Does anyone have any info on this? That's "Gelernter", and for the record David invented the concept but the lan system, about which the article was probably reporting, was developed by Jerry Leichter at Yale as part of his Ph.D. work. >Is it public domain? FTP-able? Not sure what "it" is here. At any rate, if it's code that you want we can provide some under terms that vary with the system involved (some of the systems are (or will be) licensed through Yale, others through a local company that is handling the commercial development of this work). If you would like more information, send a request to: {carriero, gelernter or leichter}@yale.edu or (just guessing): ...!decvax!yale!{carriero, gelernter, or leichter} -Nick Carriero

For whatever it's worth, there's an article `Generative Communication in Linda' in TOPLAS Jan 85.

Don't know much about this except you can get a write-up on it in: Carriero & Gelernter (sp?), "The S/Net's Linda Kernel", ACM TOCS, May 1986, pp. 110-129. Sorry, not quite sure of the spelling, misplaced the article somewhere! Oh, and TOCS means Transactions on Computing Systems, just in case. Mark

Does anyone have any info on this? >Is it public domain? FTP-able? Check the article in Computer, August 1986. Linda was implemented on AT&T Bell Labs S/Net multicomputer, MicroVAX network and an Intel iPSC hypercube but at the time of the article was still pretty shaky. Linda basically added a few simple primitives to existing languages. Gelernter address is Dept of Comp. Science, PO Box 2158, Yale Station, New Haven, CT 06520-2158. That's all I know

I have been working on a small Linda implementation written in C to run on a network of Sun Workstations. It is a very interesting and useful distributed programming language. I have read a great deal about Linda, but I am by no means an expert. Talk to Nicholas Carriero and David Gelernter at Yale for expert advice. The following are just some of the good articles on Linda: The S/Net's Linda Kernel, ACM Transactions on Computer Systems, Vol. 4, No. 2, May 1986, Pages 110 - 129. N. Carriero and D. Gelernter Distributed Communication via global buffer, Proc. ACM Symp. Principles of Distributed Computing, (Aug. 1982):10-18 By Gelernter and A. Bernstein Generative Communication in Linda, ACM Trans. Prog. Lang. Sys. 1(1985):80-112 by Gelernter. Application Experience with Linda, Proc. ACM/SIGPLAN Symp. on Parallel Programming, July 1988 by N. Carriero and D. Gelernter. Dynamic Global Name spaces on Network Computers, Proc. Intl. Conf. Parallel Processing (Aug 1984). Implementation of Tuple Space Machines, Research Report YALEU/ DCS/RR-567, December 1987 By Nicholas Carierro. I have additional references if you would like them. Take a look at the articles, you'll be suprised what this language is capable of.. Charles J.

Excuse me. I guess that is why I am still a student. I have implemented a Linda Model using C and a small kernel which runs on top of Berkeley Unix. It has just three linda functions in(), out(), and read(), to operate on the tuple space. cfleck Charles J.
