OK, so make a main(), because when you import fftclient, the "if
__name__ == '__main__'" part won't run. Change the code to

def main(): # or whatever name is appropriate
  init stuff
  while ii<problemsize:
   build_waveform
   commandsequencer
   ii = ii + 1

if __name__=='__main__':
  main()

>> cProfile.run('fftclient.__main__','fftclientprof')  ??? or ???
cProfile.run('main()', 'fftclientprof')
