In Nextflow, Does a process with a channel.fromPath is parallelized?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty height:90px;width:728px;box-sizing:border-box;
I have a process in Nextflow with multiple input file from a Channel.FromPath().
Here my script:
params.queries = ""
queries = Channel.fromPath(params.queries) #path to multiple .fasta files
process PsiBlast
input:
file query from queries_psiblast
output:
file top_hits
"""
blastpgp -d $db -i $query -j 2 -C ff.chd.ckp -Q pssm.out >> top_hits
"""
#then there are others processes, not needed for my question.
What I want to know is if my process is parallelized? If it run on 2 files at the same time for example? Or do I need to specify it in my script?
I read the doc, but it's not specify. And I don't know how to test that.

Yes, Nextflow processes are implicitly parallelised provided there's are enough cpus/mem to fulfil the parallel execution.
