Paper argues every microsecond matters for GPU collective latency

A paper on GPU collectives argues that every microsecond matters for pushing communication latency toward the speed of light. The screenshot shows the title, authors, and that most of the work was done during an NVIDIA internship.
The post also says the author is digging into Codex today and thinking about how to carry those lessons over to PCIe, suggesting a systems-level cross-over between coding tools and low-latency GPU/PCIe work.
