Can you comment something on the kind of information you intend to have in DIPort ?

Remember that you cannot send constraint variables to ports. Can you isolate the behavior to an small program? this will be also helpful.

Gustavo

Thanks Gustavo. Changing back to release 1.3.2 did help. Now I can progress a bit further. However, I am getting the following error message and the process is getting killed.

FYI, I am starting parallel Search in the following way:

functor SchedWrapper
             export
             Script
             import
             SchedRef at ‘SchedulerFunctor.ozf'  %works
             define
Script = {SchedRef.makeProblem ProblemDescription DIPort}
             end

              try
              E = {New Search.parallel init(localhost:1#sh)}
             catch X then
              {Browser.browse incatch}
              {Browser.browse X}
             end
             {E trace(true)}
             Solution = {E one(SchedWrapper $)}
             {E close}

Any idea what could be the error?

Thanks,

Ashis

1.4.0 provides a new implementation of the distribution subsystem, so
if you are concerned only with constraint programming you are not
loosing anything. This fact also explains why the parallel search is
broken in 1.4.0 and is because it relies on the implementation of the
distribution system.
