How can I make two foreach blocks go parallel?

How can I make two foreach blocks go parallel? For instance, I have two foreach blocks using different input data but doing the same calculation, each takes 32 cores, I have 64 cores in total, so to fully use the resources, I would like to make these two blocks go parallel instead of using 32 cores each time. Should I do a foreach inside foreach? Would you mind writing a toy example here? Thank you very much.
