-Emily has since ported the model to Repast Symphony, which allows more efficient execution and better control over simulation parameters.</p><p>Participants raised several questions concerning the implementation and conceptual framing. Reuse and Reproducability was another focus, NASSA was proposed as model library.</p><p>Emily also discussed her exploration of GPU computing, outlining current possibilities (switching to GPU and parallelisation) and open questions about how such acceleration could be effectively implemented in ABM frameworks.</p><h2 id=discussion-highlights>Discussion highlights</h2><h3 id=parallelisation-and-computational-strategies>Parallelisation and computational strategies</h3><ul><li>Participants exchanged ideas on the potential of parallelisation in ABM workflows.</li><li>Jim asked how Repast Symphony compares to “plain” Java implementations regarding scalability and transparency.</li><li>Not so many practical experiences seem to exist with parallelisation of ABMs, a potential aspect for further exploration</li></ul><h3 id=conceptual-reflections-on-abm>Conceptual reflections on ABM</h3><ul><li>A short discussion arose as to whether ABM is the most appropriate tool for least-cost path problems and what might be the right analytical units.</li><li>Participants considered increasing model complexity by introducing a dynamic cost surface, accounting for changing temporal and Predator-Prey dynamics.</li></ul><h2 id=other-caa-related-activities>Other CAA related activities:</h2><ul><li>Two workshops affiliated with the SSLA will take place at CAA 2026 in Vienna:<ul><li>Matteo (Code Review)<ul><li>Petr (Intro to R)</li></ul></li></ul></li></ul><h2 id=decisions-and-actions>Decisions and actions</h2><ul><li>Maintain-a-thon initiative (Zack Batist):</li><li>Agreed to launch a “maintain-a-thon” in January 2026, where members revisit older codebases, ensure they still run, document them properly, and deposit them in long-term repositories.</li><li>The initiative will be hosted via the SSLA website, accompanied by social media outreach.</li></ul><h2 id=conclusions>Conclusions</h2><ul><li>The maintain-a-thon was endorsed as a community activity promoting sustainability and transparency (January 2026).</li><li>GPU acceleration and parallelisation remain promising but complex paths for ABMs.</li><li>ABM continues to raise conceptual as well as technical questions about appropriate modelling scales and interpretability.</li><li>Sharing and refactoring experiences across platforms can strengthen collective learning within the community.</li></ul><p>Next SIG Meeting: December 2026, concrete date depending on the when2meet result (<a href=https://www.when2meet.com/?33002028-2srLL>https://www.when2meet.com/?33002028-2srLL</a>, details to be announced via mailing list)</p></div><footer class=content__footer></footer></section><section class=page__aside><div class=aside__about><div class=aside__about><img class=about__logo src=https://sslarch.github.io/images/sig_ssla_logo.svg alt=Logo><h1 class=about__title>Scientific Scripting Languages in Archaeology</h1><p class=about__description>A special interest group of <a href=https://caa-international.org/>CAA International</a> dedicated to scientific scripting languages in archaeology.</p></div><ul class=aside__social-links><li><a href=https://groups.google.com/forum/#!forum/scientific-scripting-languages-in-archaeology rel=me aria-label="Mailing list" title="Mailing list"><i class="fas fa-envelope" aria-hidden=true></i></a> </li><li><a href=https://github.com/sslarch rel=me aria-label="GitHub organisation" title="GitHub organisation"><i class="fab fa-github" aria-hidden=true></i></a> </li><li><a href=https://archaeo.social/@CAA_SSLA rel=me aria-label="Toot @CAA_SSLA" title="Toot @CAA_SSLA"><i class="fab fa-mastodon" aria-hidden=true></i></a> </li><li><a href=https://twitter.com/caa_ssla rel=me aria-label="Tweet @caa_ssla" title="Tweet @caa_ssla"><i class="fab fa-twitter" aria-hidden=true></i></a> </li></ul></div><hr><div class=aside__content><p>2025-11-07</p></div></section><footer class=page__footer><p><br><span class=active>$ echo $LANG<br><b></b></span><br></p><br><br><p class=copyright></p><p class=advertisement>Powered by <a href=https://gohugo.io/>hugo</a> and <a href=https://github.com/joeroe/risotto>risotto</a>.</p></footer></div></body></html>
