RE: [deal.II] Debug multithread code

I put MultithreadInfo::set_thread_limit(1) in main function, but still cannot do step debug in the function

assemble_neumann_contribution_one_cell. Am I doing something wrong?

Take a look at set_thread_limit:

As you can see, you can also control it using an environment variable, so you don't have to recompile.

Hi,

I find it's difficult to debug multithread code on a multiple-core computer. Sometimes it does not step into a function (I'm using vscode + wsl). Does deal.II use all the cores available? For the sake of debug, how can I limit the cores used? Is there a way to debug the code just like series one?

Regards,
Michael
