[Cbc] Parllel computations with CBC

["Büsing, Henrik"]

Dear all, 

 

I am trying to run CBC in parallel. I did a 

 

../coinbrew fetch Cbc

../coinbrew build Cbc --enable-cbc-parallel
--prefix=/work/user/METIS/Cbc/build/build_parallel/ --test

 

and then run

 

cbc -threads 16 -import model.mps –solve

 

Cbc responds with 

 

“threads was changed from 0 to 16”

 

but I do not see any CPU utilization on more than one core. 

 

Any ideas on how I could check, I did everything right? 

Thank you for your help!
Henrik Büsing
