Torsten, I'm also working on getting Mozart to run on a parallel cluster, but on WindowsXP machines (please, no flames!). I'm glad you asked that question, because I'd like to know too.
On the subject of MPI, you may already know this, but: Two de facto standards for parallel processing in C/C++ Are MPI and OpenMP. There are various implementations of the standards/APIs available as libraries. I don't know, but my guess is that Mozart follows/uses neither, but does it's own management of processing and load-balancing of constraint spaces, as with any other distributed Oz application. There are only so many ways to specify and coordinate parallel, distributed processes--you can think of parallel search as a particular case of more general distributed application processing that Mozart supports. The good news is that if you're running Mozart programs in parallel, you don't have to rewrite your applications to include parallel primitives. -------------------- George Rudolph -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Torsten Anders Sent: Thursday, May 08, 2008 11:08 AM To: Mozart users Subject: Parallel search questions Dear all, we are still working on getting Mozart running on our cluster, but things are evolving :) Two related questions. 1) Our admin asked me to "nice" our processes on the cluster nodes. Of course, it would be most convenient for us if that would be done automatically whenever we use a parallel search. I couldn't find anything in the "Parallel Search Engines" doc nor "Spawning Computations Remotely: Remote" doc how to do that. For example, is there a way to get the PID of processes remotely spawned by the parallel search facility so that we could renice them explicitly? 2) The admin is curious what method/protocol is used behind the scenes in the distributed programming model of Mozart. Hw was talking about Message Passing Interface (MPI), and I couldn't answer that.. Thank you!
