Hello again,
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">I just did a minimal test on a pair of local Linux systems here:</div>
<div class=""><br class="">
</div>
<div class="">One needs to</div>
<div class=""><br class="">
</div>
<div class="">1) install the Perl module Proc::Simple, e.g. from CPAN (<a href="https://cpan.metacpan.org/authors/id/M/MS/MSCHILLI/Proc-Simple-1.32.tar.gz" class="">https://cpan.metacpan.org/authors/id/M/MS/MSCHILLI/Proc-Simple-1.32.tar.gz</a>) to the “host”
machine where the initial mcrun.pl command will be launched from.</div>
<div class=""><br class="">
</div>
<div class="">2) Launch the simulation e.g. mcrun.pl --grid=2 BNL_H8.instr lambda=2.36 from an “otherwise empty” folder on the “host” machine. (Otherwise any file in your current directory will be attempted to transfer via scp to the slave(s) )</div>
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">- Then the simulations seem to run and are later concatenated using the mcformat utility.</div>
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">Best and hope this helps,</div>

different operating systems with my colleagues, but we want to use the<br class="">
same computing node. The openssh-server on the computing node was set<br class="">
up and rsa keys were added for passwordless authentication. Now, I am<br class="">
able to log in the computing<br class="">
node without typing the password. A "hosts" file containing the<br class="">
hostname of the computing node was created in $HOME/.mcstas/<br class="">

It seems that mcrun does not recognize the --grid option. Please help me<br class="">
to solve this problem. McStas was installed on my Ubuntu 16.04 system<br class="">
from the .deb packages following the descriptions found on the McStas<br class="">
Homepage.<br class="">

<div class="">Unfortunately it seems that you have stumbled upon an inconsistency in the documentation.</div>
<div class=""><br class="">
</div>
<div class="">The --grid option was only ever available for the Perl toolset and predates our MPI parallelisation that most people adopted instead.</div>
<div class=""><br class="">
</div>
<div class="">The mcrun.pl tool (from the mcstas-tools-perl-2.4.1 package) includes the --grid option, but I am not 100% certain that it remains functional.</div>
