I have some questions about Strand88 that may help more folks on the
mailing list understand more about the system.  I've attended a talk
about it but I don't remember it very well (was there something about
logic programming in there?) and I don't have any literature on Strand88.

So I am working strictly from the announcement...

* What is the paradigm of communication between parallel streams?
  (message passing, procedural locks, tuple space...)

* I take it that there is nothing automatic going on here in terms of
  finding parallelism.  Is that true?

* How does one "use" processors?  Do we place things, as with Occam?
  Do we ask for a certain number of processors in a particular arrangement
  and the placement is automatic?  Do we start from a single stream and
  and new ones are created by (I presume) Strand88 statements, do they
  get automatically placed on other processors?  Does the answer to
  this question differ for functional and data parallelism?

* How does implementation of Strand88 differ between multiprocessors and
  multicomputers (since both are supported)?  Would Strand88 be
  applicable to a SIMD box like the Connection Machine?

* Would it be possible to post a very small demonstration program using
  Strand88 for a data decompostion problem (like the 1D wave equation,
  for example)?

* A lot of people would say that Linda possesses the same inherent
  advantages as Strand88 (though I don't understand the scalability,
  performance-wise, of Linda (nor of Strand88 - yet)).  Are we talking
  apples and oranges or would you cite advantages over Linda?
