[Jason-users] JADE integration

[BOURDIL Pierre-A. <Pie...@sc...>]

I investigated the problem I had, relative to a 100% cpu consumption when executing the example from http://www.emse.fr/~boissier/enseignement/maop11/doc/jason-api/mini-tutorial/jason-jade/index.html
To sum up, the seller agent (ie:JadeAgArch)  never sleep.

I understood that :


1)      In class JasonTSReasonner (method action), a jade Cyclic behavior, and in async mode (the default), the agent try to sleep 1sec after each reasonning cycle . This is implemented through a call to jade.core.Behaviour.block.

2)      Nevertheless, it asks for percept to environnementAID at each perceive phase of a reasoning cycle : QUERY_REF acl message with content getPercept

3)      EnvironmentAID  answer (an INFORM ACL message), thus waking up the agent . The documentation of Jade's block clearly state that block is in fact non blocking. (http://jade.tilab.com/doc/api/jade/core/behaviours/Behaviour.html#block())

4)      Hence, the agent never sleep and consume 100% CPU.


Am I right ?
If yes, Is there a way  to  change that behavior   ? If not , how can I avoid these , maybe by allowing to put some wait from the asl sources ?
