I am trying to use bowtie2 or bwa multi-core/threads option to align my reads to genome (-p 4). I am using a MacBook pro m2 chip and it seems cannot fully parallelly use all the cores. using 'top", it shows 4/1 for threads (#TH) and only one process for bowtie2. Could someone clarify this? and let me know how to enable parallel multi-threads for using these aligners on Mac M2 chips? Thank you!
Thank you for your answer @GenoMax!
Is there a way to dynamically monitor threads usage for a specific command such as bowtie2? I previously assumed that "top" command might show such information but it seems not effective.
topwill show thread info but it will be aggregated in % (e.g. you will see 400% use for 4 cores). You could use
htopto look at individual cores. Looks for directions to install on net.
