DESCRIPTION:ABSTRACT:Unix / Linux shell programming is ubiquitous\, partly 
 due to the simplicity in which it allows combining third-party components 
 (commands) written in any programming language. Unfortunately\, this langu
 age-agnostic composition hinders automated scaleout of shell programs\, of
 ten forcing developers that deal with massive datasets to manually rewrite
  shell programs and their commands in other languages or frameworks design
 ed to scale.In this talk I will present PaSh\, a system for automatically 
 scaling out shell programs. PaSh combines a just-in-time compiler that ble
 nds static pre-processing with dynamic interposition\, a high-level annota
 tion framework for capturing partial command specifications\, and a collec
 tion of high-performance runtime primitives that support the execution of 
 parallel and distributed shell programs. PaSh achieves order-of-magnitude 
 speedups on unmodified shell programs\, all while remaining virtually indi
 stinguishable from (and requiring no modifications to) an underlying shell
  interpreter like Bash. PaSh is worked on by several institutions\, has re
 ceived multiple awards\, and is open-source software available by the Linu
 x Foundation.SHORT BIO:Nikos Vasilakis is an Assistant Professor of Comput
 er Science at Brown University. His research encompasses systems\, program
 ming languages\, and security and has been recognized by several distingui
 shed paper awards. His current focus is on automatically transforming syst
 ems to add new capabilities such as parallelism\, distribution\, and secur
 ity—against a variety of threat models. Nikos is also a co-founder of Requ
 ireSecurity\; the chair of the Technical Steering Committee behind PaSh\, 
 a shell-script optimization system hosted by the Linux Foundation\; and a 
 Research Affiliate at MIT CSAIL. https://nikos.vasilak.is
