Example of running embarassingly parallel computations on VU MIF cluster
You need to be familiar with R, ssh, git and command line. Tough luck. If you are not familiar with them, then you are not worthy to use the cluster.
First connect to MIF
ssh username@uosis.mif.vu.lt
Then do the magic required to connect to cluster
kinit
ssh cluster
Create your place on cluster
mkdir -p /scratch/lustre/username
Set it to $HOME
cd /scratch/lustre/username
setenv HOME /scratch/lustre/username ##One of the following should work
export HOME=/scratch/lustre/username
Create a directory for your R projects:
cd ~
mkdir R
Get this code
cd r
git clone git@github.com:mpiktas/mifcluster.git
cd mifcluster
Run the calculations
sbatch mpi.sh
Look out for files of type slurm-12043.out in your directory. They contain the status of your simulations. Check for error messages there.
To navigate use cd, to see content of the directory use ls, for editing use nano or vim.
To make the file exchange between cluster and your computer, consider becoming a http://github.com user. Create repository and then push and pull from server and your computer.
Consider installing screen and zsh to make the life a bit easier.
