<p class="MsoNormal">Hi all<o:p></o:p></p>
<p class="MsoNormal">(Seems this message did not get out last week, so here it is.)<o:p></o:p></p>
<p class="MsoNormal">The theory session during this week’s interop will be devoted to a discussion of what possible standard effort we might work on together.
<o:p></o:p></p>
<p class="MsoNormal">These will be organized along the following three topics that could have quite some cross-talk:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">1. implementations of the Simulation data model.<o:p></o:p></p>
<p class="MsoNormal">2. more or less standard (python) libraries for accessing cosmological simulations residing on science platforms.<o:p></o:p></p>
<p class="MsoNormal">3. data models for the raw (particles, mesh, …) and post-processing results (halos, …) of cosmological simulations<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We only have an hour, so our thoughts are that I may give a short intro for each topic. Then possibly have thoughts from one person/group who has done work in this direction, then a free discussion.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have asked Franck or Herve, or someone from the groups in France that set up a “SimDB” to say a few words on item 1.<o:p></o:p></p>
<p class="MsoNormal">I hope Matt Turk can say something on item 2 and Chris Hayward will address item 3.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">And it would be great if we can already have some discussion before the meeting, either on this thread or on the ivoa theory-ig slack channel.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Btw, the theory session is Thu Nov 4, 20:30 UTC, see <a href="https://nam02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwiki.ivoa.net%2Ftwiki%2Fbin%2Fview%2FIVOA%2FInterOpNov2021&data=04%7C01%7Cglemson1%40jhu.edu%7C4c699018a794494ff3a008d99888c3c5%7C9fa4f438b1e6473b803f86f8aedf0dec%7C0%7C0%7C637708535423746351%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=CyeVDzeaL0ypQwndXiGXy5a1pBrPV%2B%2B4BkfjKtRubss%3D&reserved=0">
