I recently read a blog post (that I'm pretty sure I found here on HN) about a person who had access to AWS P5 instances and decided to write their program to saturate the full bandwidth of these instance types. It was a multi part series and I'd only read a couple of the posts. Now I've been tearing my hair apart searching for this post but can't seem to find it.
Anyone knows what I'm talking about and has a link for me?
