Dear Mohammed,
The command i have used for parallel run is correct.
the command i have used is mpiexec -f /home/mpiuser/hosts -n 10
/home/mpiuser/espresso-5.0.2/bin/pw.x -ni 10 -nk 10

Respected Sir/Friends,
I have formed a PC beowulf cluster (X86_64 old PC's
made on 2007) and installed quantum espresso-5.2.0 in it. Now the cluster
is running very slowly than the single core i5 processor, DDR3 RAM with
1600MHZ speed. The following is my observation in single c
