ClustalO with multithreading parameter threads appear sleeping

Question

[nilaylale88]

Hello folks,

I am running clustalo with threads flag, at the begining clustalo was using the number of threads I specified but when I checked it next day, all of the threads seem sleeping except one. Do you think thats normal, or am I missing something somewhere?

Here is the code I used

clustalo --in SGFiltered_NR --out SGFilteredAligned --threads=40

and here is the picture of the htop

If the job is still running and producing output then this is normal. Every step in a multi-threaded program may not actually use all threads.
