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%7C6be3afd073424c03515808d9f0d53ae0%7Ca8eec281aaa34daeac9b9a398b9215e7%7C0%7C0%7C637805620884224335%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=xwQmlPonbqjpei34GsGzgAEmVzcJf1gk%2BbxqxAwAT7c%3D&reserved=0> and hosted under the Linux Foundation.
