Are there any elegant way to parallel processing in bash? Something like R packages "parallel" or Python module "multiprocessing"! Thanks!

GNU parallel is a very flexible tool for this, e.g.

ls *.fastq | parallel -j 8 'bwa mem ref.fa {} > {.}.sam'

Use 8 jobs, do alignment for each file in *.fastq, output is input without extension (+ .sam).
