Hello,
I 'am wondering how to 'jailbreak' CATIA to use all the available resources of my workstation? 

CATIA isn't using the available RAM/CPU/GPU to run and it takes hours for 1 boolean operation. 
my workstation configuration below !
Intel Xeon W-2125 @ 4.00 GHz (8 CPUs)
Nvidia Quadro P4000 8Go 
Hynix HMA81GR7AFR8N-VK 32GB @ 2.7 GHz
