Can Baron use parallel processing?

I use parallel processing command as below for Baron:

model.threads=0;
option minlp=baron;

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

It works. Thanks so much.

cplex.opt:
threads 4

antigone.opt:
cplex_optfile cplex.opt

how to reduce memory use of cplex

I have a model and use cplex to solve. I already set nodefileind to 3 in the opt file, which means the nodefile will be store in hard disk. However, the program still use a lot of memory, up to 13GB. Is there other ways to further reduce the memory? The version of GAMS I am using is 24.8.3
