Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 30 April 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 August 2029.

Abstract

Tensor contraction sequences are foundational computations in quantum chemistry, quantum physics, and materials science. As these workloads grow in scale and complexity, scientists increasingly rely on optimization techniques — mixed precision, reordering, and fusion — to reduce runtime and memory costs. While effective, these optimizations can introduce subtle numerical errors that are difficult to detect and that…
