Google Julia

Julia Facts Released: February 2012 Used in 6 MIT classes involving scientific computing Technical Computing Environment – New – Fast – Human – Open Source – Flexible – Scalable for “big data” and “many processors” You don’t need our permission to try it, or to contribute Eliminates the word “prototype” – Solves the two language problem People just seem to like it

Julia in the News “Julia“Julia is a new language for scientific computing that is winning praise from a slew of very smart people, … As a language, it has lofty design goals, which, if attained, will make it noticeably superior to Matlab, R and Python for scientific programming.” TechCrunch Written by the author of “Machine Learning for Hackers”

Every Day a New Package At least 200 by now A hot optimization algorithm used in machine learning! Implemented using Julia’s asynchronous parallel technologies

Julia: Parallel Histogram 3 rd eigenvalue, pylab plot, 8 seconds! 75 processors Page 6

Linear Algebra too limited in Lets me put together what I need: e.g.:Tridiagonal Eigensolver Fast rank one update Arrow matrix eigensolver can surgically use LAPACK without tears Page 7

Julia Documentation Well written! – google: julia documentation Much of Julia is written (elegantly!) in Julia – it won’t take you long before you start looking at Julia to learn Julia Julia cheatsheet Julia videos Ijulia notebooks (see max, plus algebras) 

IJulia MIT Classes serve up Julia on the Cloud No keys No installation: – No more, Download, Next, Next, Next, Install No friction to computation No need to update Built on Ipython CHANGES EVERYTHING!
