Python -O won’t magically make every script faster, but in the right workloads it’s a free win—here’s how to test it safely.

We evaluate patches by applying them, running the correctness suite, and measuring runtime speedups vs. the expert (human) PR, reporting Speedup Ratio (SR). Performance improvements in widely used ...

Abstract: Block-structured Adaptive Mesh Refinement (AMR), while essential for improving efficiency in large-scale irregular and dynamic simulations, poses unique optimization challenges. Previous ...

Oh, sure, I can “code.” That is, I can flail my way through a block of (relatively simple) pseudocode and follow the flow. I ...

Abstract: Code embedding represents code semantics in vector form. Although code embedding-based systems have been successfully applied to various source code analysis tasks, further research is ...
