<p>Hi Margherita,</p>
<p>in CP2K, all MPI routines are gathered in a wrapper that you can
find in "src/mpiwrap/message_passing.F". For examples where
MPI_WAIT and MPI_WAITALL are called, I suggest you grep for
"mp_wait" and "mp_waitall".</p>
<p>Best,</p>
<p>Augustin<br>

Dear all,
<div>I am writing a module for CP2K but I am very much struggling
to get the parallel executable (cp2k.psmp) to work (the serial
one, cp2k.ssmp, works correctly and as expected). I believe I
need to use routines such as MPI_WAIT or MPI_WAITALL to deal
with this issue but I don't know exactly how these are included
in CP2K. Can anyone point me in the direction of the
modules/subroutines which are used to handle communication
between MPI processes in CP2K? Any additional information on how
they (the main ones) work would also be greatly appreciated!</div>

<div>Thank you in advance!</div>
