I use parallel processing command as below for antigone:

model.threads=0;
option minlp=antigone;

However, I did see all the cores are used as I used cplex. Actually, only one core is used. Does antigone support parallel processing?

GAMS/Antigone has an option "cplex_optfile". You might want to try to set the threads option inside the cplex.opt file:

cplex.opt:
threads 4

antigone.opt:
cplex_optfile cplex.opt

It works. Thanks so much.
