<div>Greetings:</div>
<div><br>
</div>
<div>In the MRCC interface of molpro2012.1, </div>
<div><br>
</div>
<div>Molpro/src/util/mrcc_intface.F around line 326 is the code that writes out the shell command that invokes MRCC</div>
<div><br>
</div>
<div> test=mrccexec(1:ll)<br>
$ //' | sed -e "s/--/- /g" | tr -d "\000" >> '<br>
$ //trim(output)<br>
<br>
</div>
<div>I wonder if this feeding through sed and tr filters still has any purpose with recent versions of MRCC? Its main actual effect, at this point, seems to be to introduce a level of output buffering that makes it impossible to monitor a heavy MRCC job. If
I replace the two pipe segments by a single one "' | sed -e "s/--/- /g” -u >> ‘ (the -u switch minimizes buffering in sed) then at least the .xml output file can be used for real-time MRCC job monitoring.</div>
<div><br>
</div>
<div>In fact, if I just replace both pipes by spaces, nothing bad seems to happen either.</div>
<div><br>
</div>
<div>Does this MRCC output “pipelining” still have any purpose?</div>
<div><br>
</div>
<div>Best regards</div>
