Please note that a bug in the new "poe" environment of sp5 machines
may cause a dramatic slowdown of quantum-espresso in parallel 
execution. Workaround: 
set environment variable MP_STDINMODE to 0, as in
  export MP_STDINMODE=0
for sh/bash,
  setenv MP_STDINMODE 0
for csh/tcsh; or start the code with option "-stdinmode 0" to poe:
  poe -stdinmode 0 [options] [executable code] < input file
