Hello.
I run abinit and it uses only around 30% of CPU and 21% memory. I would like to use full percentage of it to speed up
calculation.
I appreciate any advice or cause of small % of CPU usage.
Attached is my configuration.

Hello jbeuken,
Thank you for reply. I would use OpenMP with 12 threads options, that is,
mpirun abinit -c 12 < files_file

Re: Abinit uses small percentage of CPU
Hi,
there is a "syntax" error :
mpirun abinit -j 12 < files_file
Of course, don't forget to compile ABINIT with OMP support ( intel : -qopenmp , gnu : -fopenmp )
