Julia

Julia is a high-level, high-performance dynamic programming language for technical computing, with syntax that is familiar to users of other technical computing environments.

Interactive Usage

After connecting to iceberg (see Establishing a SSH connection), start an interactive session with either the or qrsh or qrshx commands.

The latest version of Julia (currently 0.5.0-rc3) is made available with the commands

module load compilers/gcc/5.2
module load apps/gcc/5.2/julia/0.5.0-rc3

This adds Julia to your PATH and also loads the gcc 5.2 compiler environment with which Julia was built.

Start Julia by executing the command

julia

You can exit a Julia session with the quit() function.

Installation notes

These are primarily for administrators of the system.

Julia was installed using gcc 5.2

module load apps/gcc/5.2/git/2.5
module load compilers/gcc/5.2
module load apps/python/anaconda2-2.5.0

git clone git://github.com/JuliaLang/julia.git
cd julia
git checkout release-0.5
#The next line targets the NEHALEM CPU architecture. This is the lowest architecture available on
#Iceberg and so the resulting binary will be supported on all nodes. Performance will not be as good as it
#could be on modern nodes.
sed -i s/OPENBLAS_TARGET_ARCH:=/OPENBLAS_TARGET_ARCH:=NEHALEM/ ./Make.inc
make
