CPU usage on cluster machine


(Lmanchon) #1

–Hi all,

I have pointed that in Qiime analysis the use of the maximum number of CPUs of a machine is not better and not faster, as processes running on each core waste a lot of time in waiting and communicate for each other. For example using deblur or dada2 with 40 cores is less faster than using 16 cores.
