Introduction
Julia is a high-level, high-performance, dynamic programming language, being designed with scientific computing in mind. Parallel programming features, such as multi-threading are included in the core language, while there also exit packages leveraging the power of MPI and CUDA.
Interactive Example
Load Julia module and start interactive REPL session with 8 threads, using the environment in the current directory:
$ module load math/julia $ julia -t 8 --project=.
Enter ']' to go into package manager and install package UnicodePlots.
add UnicodePlots
Leave the package manager with the backspace key.
Create an vector with 64 elements set to 0 and fill it using all threads with the corresponding tread id number.
vec = zeros(64)
Threads.@threads for i in eachindex(vec)
vec[i]= Threads.threadid()
end
Load the UnicodePlots package and draw a scatter plot of the contents of vec
using UnicodePlots scatterplot(vec)
Further documentation
- Julia Workshop at HLRS: The material of this workshop is in large parts also valid for the Justus cluster (on Justus you only need the module math/julia).
