<div dir="ltr">Hi Ian, Carlos, <br><br>thanks a lot for your feedback. <br>Together
with Miguel Zilhao we are planning to perform these scaling tests using
the Einstein Toolkit together with the McLachlan and/or our own
evolution thorns on the Cosmos cluster at the University of Cambridge.<br>If you are interested, we would be happy to make the results available to the community and to the public, e.g., on the wiki. <br><br>We
were thinking about evolving a head-on collision of two black holes to
avoid contamination by the initial data construction. We would restrict
the output to "carpet-timing..asc" and "AllTimers*". Would you recommend
any other output to monitor the performance during these tests?<br>Please let us know if you have any other comments.<br><br>Best wishes,<br>Helvi & Miguel<br></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">===========================================<br>

Among the required technical information are scaling tests. While we will perform our own tests I also checked for "official" information for the ET.

For someone running simulations very similar to those used, referring to such a paper may be sufficient to demonstrate scaling of the code for a proposal. If the code used was quite different, then if the parameter files and any required scripts from such a paper were made public, it would be easier for each group to adapt them to their own code.</div></div><div><br></div><div>
