Description
I read the document https://ml-explore.github.io/mlx/build/html/dev/extensions.html#implementing-the-cpu-back-end, and I need to develop a new primitive in my project. I found that the example custom cpu kernel is a single thread one, how can we implement a multi thread cpu kernel? Is there any example?
