Hello everyone,



   Nutshell of my request: I'm looking for examples or experience with anyone 

running MASON instances in multiple threads in ECJ and getting the results out 

of the MASON instance for fitness purposes



   Background/request: I'm working on a project where I'm doing some 

evolution with ECJ (version 20) using MASON (version 15) to run simulations.  

However the model I'm trying to run on MASON take a very long time, so I 

thought I'd try to speed up by running MASON in multiple threads.  I 

understand that ECJ can do evaluations in multiple threads, and in theory I can 

just run MASON in these multiple threads.  Normally one can get the results 

from MASON via a static method/variable in SimState class.  However since I 

want to run multiple MASON instances in multiple threads, I can't really use a 

static variable/method, so I'd need to use class variable in the MASON 

instance.  However because of the way MASON instances are instantiated and 

run (within the doLoop() method in the SimState class, there is no obvious or 

easy access to the instance itself.  I can probably work around by copying 

most of the code in the doLoop() into my code so I'd have access to the 

MASON instance.  But before I do that, I just wanted to check to see if anyone 

here has worked with ECJ and MASON where ECJ run multiple MASON 

instances in multiple threads and able to get results from all these 

simulations?



   Thanks everyone!
