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
