<p>Hallo,</p>
<p> </p>
<p>first thank you for your advice. I will make a google group until tomorrow, where we could discuss how to integrate SPH in the ET.</p>
<p>Roland, to your question, I am not sure which major problem you mean regarding the MPI process, but I have made test how to couple SPH with a grid based background and how to take advantages from the grid.</p>
<p>I am afraid I could not call in into today´s ET phone call.</p>
<p> </p>
<p>Regards,</p>
<p>Stefan</p>

<pre>Hello Stefan,</pre>
<blockquote type="cite" style="padding-left:5px; border-left:#1010ff 2px solid; margin-left:5px">long time ago i asked about a SPH modul in EinsteinToolkit for my PhD thesis. It took more time i thougt, but i am still working. From what I can tell from the email thread from January 2014 the</blockquote>
<pre>discussion there was on how to couple and SPH hydro code to the
spacetime solver in Cactus and how to handle the particles moving
between MPI processes. Judging from your current email you made some
progress in the direction?</pre>

<pre>For a post I think it is fine if you just add the Einstein Toolkit logo
(the little Einstein
<a href="https://einsteintoolkit.org/global/images/einstein.png">https://einsteintoolkit.org/global/images/einstein.png</a>). If you want to
add a reference to the poster, I would use the ET website URL. We have a
section on citing policies on the website:
<a href="https://einsteintoolkit.org/documentation/licenses/">https://einsteintoolkit.org/documentation/licenses/</a> where the main
publication is Loffler:2011ay in
<a href="https://einsteintoolkit.org/manifest/einsteintoolkit.bib">https://einsteintoolkit.org/manifest/einsteintoolkit.bib</a></pre>
<blockquote type="cite" style="padding-left:5px; border-left:#1010ff 2px solid; margin-left:5px">Second i made necessery preparatory work and will now try to integrate the SPH algorithm. I am sure it could be helpful not working alone on it, so i could open a google group for communication, if somebody want.</blockquote>
<pre>It will probably be helpful to get some support from at least one of the
ET people (incl. me). I am fine trying to help out with anything that
has to do with how to integrate an SPH code into the existing framework
and the technical details on eg how the scheduling and the interpolator
works, and given that I am (usually) the same timezone as you are you
may expect me to reply to a lot of questions first. Matt Kinsey
(GeorgiaTech) who also worked with many particles has experience in how
to make this work fast.
A Google group would be fine to unclutter the mailing list with the
technical discussions.
Would you be able to call in into Mondays ET phone call once more?
Yours,
Roland
