A Tour of Julia

By Erik Engheim

A high performance, just in time compiled dynamic language, which gives python like productivity with C/C++ style performance. We will get into the details of why this seemingly impossible task was made possible through clever language design. Then we will geek out by generating LLVM byte code and x86 assembly code for individual functions interactively at the command line, explore meta programming with Julia’s LISP style macros and learn about Julia’s powerful multiple dispatch mechanism and how it differs from function overloading.

Julia is an upcoming language being embraced by the scientific and high performance computing community, running projects like Celeste on 650 000 cores processing 178 terabytes of astronomical data.
