(Sorry if this is a double, my first posting did not seem to enter the newsfeed) Does anybody have any refences to work about the Parellel object oriented language POOL-T, especially the formal semantics it is said to have. Other information about POOL-T is also appreciated, like email addresses to the persons at PHILIPS/Holland involved in POOL. Short summary of what I know. POOL-T is an object-oriented parallel language where every object is a process. The objects have a body and show explicitly when they are ready to accept messages (they also say which messages they want to accept). There is (currently) no inheritance in the language. It is meant to run on DOOM (distributed object oriented machine). Both the language and the machine is made by PHILIPS in holland in esprit project 415. A prototype of the machine is(will soon be?) running on a network of 100 MC68020, each with own memory. That information was taken from an article by Pierre America (POOL-T - A Parellel Object-Oriented Language) in the book Object-Oriented Concurrent Programming (Yonezawa,Tokoro; MIT Press 1987) and a leaflet describing Esprit project 415. mikael -- Mikael Eriksson (Email: mikael@sm.luth.se) ......... You are in error. 2+2=5 Thank you for your cooperation. The Computer.

POOL-T is a parallel object-oriented language developed at our lab. In the
mean time is has been replaced by POOL2, which is based on the same
principles but provides some more convenient notation to the programmer
("syntactic sugar"). POOL2 is intended to run on DOOM (decentralized
object-oriented machine). A 12-processor prototype of this machine has been
running for several months now, a 100-node prototype is under construction.
Language definitions for POOL-T and POOL2 are freely available from us. For
POOL-T, an interpreter/simulator running under Unix (on sequential machines)
is also available; for POOL2 these will become publicly available soon.
POOL is also the subject of studies in formal semantics and proof theory. A
paper about its operational semantics appeared in POPL '86. An article on its
denotational semantics will appear in Information and Computation.
For more information, you can send your (ordinary mail) address to me,
indicating your interest.
