SLURM usage guide ---------- If you are completely new to scientific computing, read this: Please keep in mind that simply throwing a serial program without provisions for parallelization at the cluster will not make it run faster. In fact, it will often run SLOWER, since cpu cores on machines specialized in scientific computing usually run at lower clock frequencies than workstation cpus.
