Julia

module avail julia/

Julia is a high-level, high-performance dynamic programming language for numerical computing. It provides a sophisticated compiler, distributed parallel execution, numerical accuracy, and an extensive mathematical function library.

Usage

Ideal way how to use needed Julia modules is to install them into your home directory.

$ module add julia
$ export JULIA_PKGDIR=$HOME/.julia   # suppose we are on brno2 storage
$ julia
julia> import Pkg
julia> Pkg.status()
julia> Pkg.add("MPI")       # install e.g. MPI package

Julia usage on frontend

$ export JULIA_PKGDIR=$HOME/.julia   
$ export JULIA_DEPOT_PATH=$HOME/.julia
$ export JULIA_PROJECT=$HOME/.julia 
$ export JULIA_CPU_THREADS=$PBS_NCPUS
$ export JULIA_CPU_THREADS=1          # we recommend to limit CPU to 1 or 2
$ julia
julia> Pkg.status()         # lists MPI package

Julia usage in a job

$ export JULIA_PKGDIR=/storage/brno2/home/username123/.julia   
$ export JULIA_DEPOT_PATH=/storage/brno2/home/username123/.julia
$ export JULIA_PROJECT=/storage/brno2/home/username123/.julia 
$ export JULIA_CPU_THREADS=$PBS_NCPUS   # PBS_NCPUS is number of reserved CPUs
$ julia
julia> Pkg.status()       # lists MPI package
