- Hi, everybody!
-
- Three weeks ago I posted a news requiring imformation about current
- work on skeletons. Here I will give a summary about the responses I
- got:
-
- From jampel@cs.city.ac.uk Mon Dec 7 11:35:44 1992
-
- I suggest you contact Professor John Darlington at Imperial College,
- London.
- Email is (probably) j.darlington@doc.ic.ac.uk
- He has been working for quite a few years in 'Transformation
- for Parallelism' using skeletons.

-
- You should get in touch with Murray Cole at Edinburgh University.
- I believe he did this or something similar as his PhD topic.
- I don't know his e-mail address.

- In reference to your search for skeletons, you might want to look at
- a new paper (submitted to a journal) entitled "Generating Programs by
- Reflection". It is available as OGI tech report 92-015 it can be gotten
- over the net by
- ftp cse.ogi.edu
- cd pub/tech-reports/1992
- get 92-015.ps.Z
- This paper outlines a systematic way to generate skeletons of programs for
- arbitrary types. The referees have pointed out a bug in one
- of the proofs (which hasn't been fixed yet) so please don't distribute
- this version. I though you might want to take a look at it.

- I'm replying to your message on news-net concerning the use of higher
- order skeletons in the development of parallel functional programs. I'm
- working on a data parallel lazy functional language based upon Haskell,
- in which parallel algorithms can be expressed. I've included part of a paper
- I've been writing that develops parallel versions of the higher order
- functions map, scan and fold. The aim of the notation I propose
- is that people write general higher order parallel functions, that can easily
- be re-used.

- Ich habe gerade Dein Posting in den News gelesen und war aeusserst
- interessiert. Grund: Ich arbeite zur Zeit hier in Aachen an der
- selben Sache. Meine Zugrunde liegende Hardware ist ein Transputer-
- System. Da ich im "Graduiertenkolleg Informatik&Technik" bezahlt werde,
- ist meine Ausrichtung (in der Implementierung) wahrscheinlich ein
- klein wenig praktischer ausgelegt... Meine Skelette muessen am Ende
- dann "num_diff_skelett" und so heissen.
-
- Stand der Dinge bei mir ist zur Zeit:
- - eine abstrakte Maschine ist implementiert, die zur Zeit aber nur
- reinen funktionalen Code vertraegt.
- - Ich habe angefangen, den Datentyp Array in C-Manier zu implementieren.
- Hier suche ich zur Zeit noch eine gute Theorie als Grundlage, die
- mir ein "single threading" ermoeglicht. (Peyton-Jones Monads sind
- nicht ausreichend, es soll da aber noch was von Hudak und von einem aus
- Nijmegen geben.)
- - Insbesondere auf diesem Datentyp sollen dann Skelette - als higher-order
- Funktionen in C geschrieben - arbeiten. Neben dem gerade angesprochenen
- numerischen Differations Skelett sind Skelette wie divide&conquer,
- branch&bound, Pipe, ... ins Auge gefasst. Aber wie gesagt: bisher noch
- nicht implementiert (hoffentlich hab ich in ca. einem Monat erste Ergebnisse).
- An Literatur fallen mir die folgenden Dinge ein:
- Murray I. Cole: Algorithmic Skeletons: Structured Management of Parallel
- Computation, Pitman/MIT-Press 1989
- Das ist wohl seine PhD Thesis, inzwischen als Buch veroeffentlicht (?).
- Ich hab noch die Thesis - kam mal ueber Schriftenaustausch aus Edinburgh
- hier an. Die dortige Nummer ist: CST - 56 - 88, October 88
- Darlington et al: Structured Parallel Functional Programming
- 3. International Workshop on the Parallel Implementation of
- Functional Languages 1991.
- Zu dem Workshop gibt es auch nur einen internen Report aus Southampton.
- Bratvold: Determining Useful Parallelism in Higher Order Functions
- 4. Internationaler und so weiter. Diesmal in Aachen.
- Der Tagungsband ist f"ur 20,- DM zu haben bei uns, oder Du gehst
- via anonymous-ftp auf den Rechner ftp.informatik.rwth-aachen.de,

- From tore@cee.heriot-watt.ac.uk Tue Dec 8 10:27:05 1992
-
- There seems to be an increasing interest in skeletons these days. The
- major work (past & present) in the area that I'm aware of is:
- - Hewlett-Packard/University of Pisa
- The P4 project/P3 language
- - Imperial College, London
- Prof. Darlington's group
- Paul Kelly's Caliban
- - University of British Colombia
- TOPS
- - University of East Anglia
- ZAPP
- - University of Edinburgh
- Murray Cole's work on Algorithmic Skeletons
- Edinburgh Parallel Computing Centre, skeletons in ML
- Some interesting work has been carried out by John Reekie (University
- of Technology, Sydney) and Fethi Rabhi (University of Hull). David
- Skillicorn's ideas on architecture-independent parallel computation and
- the Bird-Meertens formalism are also worth looking at.
- Here at Heriot-Watt (Edinburgh) we've done some work on exploiting parallelism
- in HOFs for high-level image processing. I'm currently working on general
- methods for extracting and exploiting parallelism from functional programs
- based on skeletons, and there is also David Busvine's forthcoming thesis on
- detecting parallel structures in functional programs.
- Hope this helps. I would appreciate if you could share with me, alternatively
- summarise to the net, other responses you get to your posting.

- I have been interested in this area for a while. There is a lot of work in this
- vein at Imperial College, London, in David Skillicorn's group at Queen's, Kingston,
- by Rabhi at Hull and others. Here are some refs, some of them more relevant than
- others. I'd be very interested to hear what else you discover!

-
- My thesis ("Algebras for Tree Algorithms", PRG, Oxford, 1991, available as
- technical monograph PRG-94) is about accumulations on trees, a particular
- kind of higher-order operation on trees. I've just written one and a half
- papers on implementing these accumulations efficiently on PRAM machines.
-
- David Skillicorn <skill@qucis.queensu.ca> believes that the data-parallel
- style induced by higher-order operators makes a good
- architecture-independent parallel programming language. I can send you refs
- if you want.
-
- I would be interested in seeing anything you have written so far, and in
- your thesis when it is completed. Please send me a summary of the replies
- you receive, too!
-
- Cheers,
-
- Jeremy
