*Description*

Hi, I have a stupid question. I am running a relatively complicated project with approximate 800,000 gates. But it's running very slow. Now it's still on run in the Global Routing stage after almost 2 days' running. And after checking the CPU resources utilization, I found out there is only one CPU core running the "openroad" command. So openroad is a single thread process? How can I make it run in multi CPU cores parallelly? Or it there any method to make the flow running faster?

*Proposal*

Improve the running speed to complete the a bit complex projects
