Hi,<br>
Thanks for the solutions you proposed. I tried most of them, and the
results are summarized below:<br>
<blockquote cite="mid:mailman.1592.1247652522.1425.pw_forum@pwscf.org"
type="cite">Is is not impossible, but normally the standard
redirection ">" works with (open)mpi out-of-the-box. If you cannot
find the output file it may indicate that the working directory used by
mpirun is not the directory in which you are looking for the output
file; see the "Current Working Directory" section of mpirun manual for
details. You can set the working directory explicitly using the option
-wd "/path/to/directory" to settle this issue.
<br>

I tried, and it does not change anything. Just to let you know, when I
do a ssh on each node, I get the same files and directories as on the
master node (don't know if this helps...).<br>
<blockquote cite="mid:mailman.1592.1247652522.1425.pw_forum@pwscf.org"
type="cite">Another issue I've had sometime, that could cause problems
similar to the one you've had, is related to two conflicting version of
mpi. The mpirun instance on the master node tries to start the wrong
mpirun on the other nodes. Use the --prefix option to be sure this is
not your case (syntax example: "mpirun --prefix /opt/openmpi-1.3.1"
without "/bin/")
<br>
</blockquote>
I have not tried this yet. I tried to change a few things that I
believe are related to similar issues and explained on the user guide,
but I am not sure I did this well (besides, reading it again, it does
not seem to apply for openMPI, does it?). <br>

Where are the typical locations where environmental variables are
changed: my .bashrc file (I am using the bash environment)? What is
the correct syntax to do this?<br>
<br>
<blockquote cite="mid:mailman.1592.1247652522.1425.pw_forum@pwscf.org"
type="cite">just use " > ". If redirection doesn't work on your
system,
<br>
that's another story.</blockquote>
Redirection does not seem to work.<br>
<br>
<blockquote cite="mid:mailman.1592.1247652522.1425.pw_forum@pwscf.org"
type="cite"> You can go to PW/startup.f90 and change
<br>
<br>
IF ( me_image /= root_image ) &
<br>
OPEN( UNIT = stdout, FILE = '/dev/null', STATUS = 'UNKNOWN' )
<br>
<br>
into
<br>
<br>
IF ( me_image /= root_image ) THEN
<br>
OPEN( UNIT = stdout, FILE = '/dev/null', STATUS = 'UNKNOWN' )
<br>
ELSE
<br>
OPEN( UNIT = stdout, FILE = 'some_file_name', STATUS = 'UNKNOWN' )
<br>
END IF
<br>
</blockquote>
I tried and it seems to work. PWscf now does write the output in the
file 'some_file_name'. So I guess that the idea is then to use the
command 'mv' in my script to change this file (thus used as a temporary
file fir each job) to the file name I want. Am I correct?<br>
Am I then supposed to apply these changes to all the programs I want to
use (e.g. gipaw.x, band.x, and maybe others) ?<br>
<br>
Thanks.<br>
