Dear Christian,
   we have done something similar on 32 processors. You must use
RemoteEclipse or OutOfProcessEclipse and not EmbeddedEclipse.. Check this
part of documentation:
http://www.eclipse-clp.org/doc/embedding/embroot048.html for more details.
All you have to do is to send ruleset to each prolog engine separately.
After this you can call them asynchronously.

Best regards
