You can also test the container I have already built, it is available on Comet at:
/oasis/scratch/comet/zonca/temp_project/julia.img
Choose a location:
IMAGE=/tmp/julia.img
Make sure to have singularity 2.2 installed, create an empty image:
sudo singularity create -s 4096 $IMAGE
First use the official Docker image for Julia based on Debian Jessie to inizialize it:
sudo singularity import $IMAGE docker://julia
Then run the bootstrap file to install mvapich, more Julia packages, including MPI.jl:
sudo singularity bootstrap $IMAGE debian_julia.def
Julia packages are not installed in the home of the user as usual but in /usr/local/julia.
Copy the image to Comet
scp $IMAGE comet.sdsc.edu:/oasis/scratch/comet/$USER/temp_project/
Modify the run_singularity.slrm script to test your job.
In case of MPI errors, install the MPI package in your home folder,
get a shell inside the container:
singularity shell $IMAGE
Open the Julia terminal:
/usr/local/julia/bin/julia
Install and build MPI.jl:
julia> Pkg.add("MPI")
julia> Pkg.build("MPI")
