run taichi using multiple cpus

[liuyunpu]

Concisely describe the proposed feature it seems taichi cannot use two cpus(two cpus on one motherboard) when using cpu backend, only one cpu is working, as shown below.

Will taichi supports multiple cpus in the future?

Hmmm, so far we only support using multi-cores of a single CPU. I think it's a long way to go to support dispatching kernel tasks across different CPUs

As a workaround, you may manually divide tasks and use process pool to launch mutilple kernels to utilize multi-cpu, which is how our project works for now.

thanks, that seems a viable solution
