[Pw_forum] what's the difference between 'md' in pw.x and cp.x

'md' in PWscf may most likely be BOMD.

  Dear all,

  I want to perform ab initio molecular dynamics calculation via Q-E. I found both cp.x and pw.x could undertake this calculation.
  I wonder what's the difference between 'md' in pw.x and cp.x, and if I could achieve the same final geometry for same systems (the coordinates of atoms, temparature, box dimensions and K-ponits etc. are exactly the same) by this two methods.
  Do you think both 'md' calculation in pw.x and 'cp' in cp.x could be regard as the 'Car-Parrinello Molecular Dynamics' calculation and do the almost the same thing as the 'CPMD' codes copyrighted jointly by IBM Corp.

  thank you for reading 

  best,

  vega
