Re: I think its not reading the number of cores right

• How do I know how many cores parallel is seeing?
  
  

On my Fedora 37 laptop:

$ parallel --number-of-cores

14

$ parallel --number-of-cpus

14

That seems to be the number of P cores because my laptop has an i7-12800H where grep -c processor /proc/cpuinfo​ returns 20.

My command line is 

parallel --gnu --no-run-if-empty -k --lb -j-5 --colsep ' '  processx "{1} {#}" :::: ${FILE}

and the file has 100.000 lines

my box has 44 cores, minus 5, I should see 39 processes, but using ps ax | grep bash, I see only 10.

How do I know how many cores parallel is seeing?
