You can find them here:  http:  www.stochasticlifestyle.com     I am by no means an expert on Julia, but I put some tutorials for some ways I have been using Julia, like how to use Julia on the XSEDE Comet HPC  which you can test out too via a startup allocation! , optimizing some FEM codes, etc. After I publish a few things I'll get back onto this and document some experiments I am doing like interfacing with the Xeon Phi and writing stochastic  partial  differential equation solvers. I hope these tutorials helps somebody out. And feel free to comment. I still have lots to learn about Julia as well.     Jeffrey Sarnoff    Feb 23   I found  Using Julia's Clanguage interface  clear, clean, copyable.  Thanks for contributing.      Tim Holy    Feb 23   On this one:   http:  www.stochasticlifestyle.com multi-node-parallelism-in-julia-on-an-hpc    it looks like you're running performance-critical code at global scope. If you  put it in a function  and check that it's type-stable, etc , your single-  threaded code might outperform your parallel version.  Of course, you can  combine the two to do even better, sometimes.    See http:  docs.julialang.org en stable manual performance-tips    --Tim       Chris Rackauckas    Feb 23   It's not in the global scope. I always wrap it in a function call. Maybe I should make that more explicit.
