Title: PaSh: Light-touch Data-Parallel Shell Processing

Abstract:
"In this talk I will present PaSh, a system that exposes data parallelism in POSIX shell scripts. To achieve that, PaSh offers: (i) an order-aware dataflow model that precisely captures a fragment of the shell, (ii) a set of dataflow transformations that extract parallelism and have been proven to be correct, and (iii) a lightweight framework that captures the correspondence of shell commands and order-aware dataflow nodes. PaSh achieves orders-of-magnitude performance improvements on a variety of scripts found in the wild. PaSh is open-source https://github.com/binpash/pash<https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fbinpash%2Fpash&data=04%7C01%7Cwagner.andr%40northeastern.edu%7Cec989f35b4b54d6045d108d9f6f8ab2e%7Ca8eec281aaa34daeac9b9a398b9215e7%7C0%7C0%7C637812371328611134%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C2000&sdata=OiE82fCN5EBb1v3bG8OEUCkZ%2FMjx4x5ZfrEQ3a6eY4M%3D&reserved=0> and hosted under the Linux Foundation.
