Swiss, and so are its names: both halves of the system are named after places in the Alps that are, in one way or another, about moving a <em>lot</em> of something up a steep mountain as efficiently as possible — usually by train. Throughput, in other words.</p> <table> <thead> <tr class=row-odd ><th class=head ><p>Part</p> <th class=head ><p>Name</p> <th class=head ><p>What it does</p> <tr class=row-even ><td><p>Streaming / acquisition</p> <td><p><strong>Jungfraujoch</strong></p> <td><p>Receives detector data at high data rates, runs the FPGA/GPU pipeline, and streams images out for writing.</p> <tr class=row-odd ><td><p>Data processing</p> <td><p><strong>Rugnux</strong></p> <td><p>Offline crystallographic analysis of a stored dataset — indexing, integration, scaling and merging (the <a class="reference internal" href=RUGNUX.html ><span class="std std-doc"><code class="docutils literal notranslate"><span class=pre >rugnux</span></code></span></a> tool).</p> </table> <section id=jungfraujoch > <h2 id=jungfraujoch >Jungfraujoch<a class=headerlink href="#jungfraujoch" title="Link to this heading">¶</a></h2> <p>The <strong>Jungfraujoch</strong> is a high mountain col in the Bernese Alps, the saddle (<em>Joch</em> is German for “yoke” or “col”) between the peaks <strong>Jungfrau</strong> and <strong>Mönch</strong>, at 3,466 m. It is the site of the <a class="reference external" href="https://www.hfsjg.ch/">High Altitude Research Station Jungfraujoch</a>, whose long-running atmospheric measurements are <strong>co-operated by the Paul Scherrer Institute</strong> — the same institute that develops this software and the JUNGFRAU detector.</p> <p>The name is also a small piece of word-play. PSI’s <strong>JUNGFRAU</strong> detector and DECTRIS’s <strong>EIGER</strong> detector are both named after Bernese Alps peaks (the famous trio is <em>Eiger</em>, <em>Mönch</em>, <em>Jungfrau</em>). The Jungfraujoch — the pass <em>between</em> Jungfrau and Mönch — is where those two detector worlds meet.</p> <p>And it fits the theme of the whole project: the Jungfraujoch is reached by the <strong>Jungfraubahn</strong>, whose terminus is the <strong>highest railway station in Europe</strong> (3,454 m, the “Top of Europe”). It is the closest you can get to that summit in a genuinely <em>high-throughput</em> way — by train, moving crowds up the mountain — which is exactly what the streaming side of this software does with detector frames.</p> <p><strong>Pronunciation (German):</strong> <em>Jungfraujoch</em> ≈ <strong>YUNG-frow-yokh</strong>. “Jung” as in <em>young</em>, “frau” rhymes with <em>cow</em>, and the final “joch” ends in the guttural <em>ch</em> of Scottish <em>loch</em> or German <em>Bach</em> — not a hard <em>k</em>.</p> </section> <section id=rugnux > <h2 id=rugnux >Rugnux<a class=headerlink href="#rugnux" title="Link to this heading">¶</a></h2> <p><strong>Piz Rugnux</strong> is a mountain in the Rhaetian Alps of canton Graubünden, in south-eastern Switzerland. (<em>Piz</em> is the Romansh word for “peak”.) It rises above the <strong>Albula line</strong> of the <strong>Rhaetian Railway</strong> (<em>Rhätische Bahn</em>), part of the “Rhaetian Railway in the Albula / Bernina Landscapes” — a <strong>UNESCO World Heritage Site</strong> (<em>Welterbe</em>).</p> <p>That stretch of line is a masterpiece of throughput engineering: to climb a great deal of altitude in very little horizontal distance, it corkscrews through a series of <strong>helical (spiral) tunnels</strong> looping back inside the mountains. It is, again, the Swiss art of getting an enormous amount up a steep mountain efficiently — the same idea the data-processing side of this software is built around: pushing a large volume of diffraction data through the analysis pipeline.</p> <p>So the theme is consistent — <strong>Swiss mountains, trains, and throughput</strong> — while keeping the two subsystems clearly distinct: <em>Jungfraujoch</em> streams, <em>Rugnux</em> processes.</p> <p><strong>Pronunciation (Romansh):</strong> <em>Piz Rugnux</em> ≈ <strong>peets roo-NYOOKS</strong>. The “gn” is a soft palatal <em>ñ</em>, as in <em>canyon</em> or Italian <em>gnocchi</em>, not two separate sounds.</p> </section> <section id=what-is-romansh > <h2 id=what-is-romansh >What is Romansh?<a class=headerlink href="#what-is-romansh" title="Link to this heading">¶</a></h2> <p><strong>Romansh</strong> (<em>Rumantsch</em>) is the <strong>fourth national language of Switzerland</strong>, alongside German, French and Italian. It is a Romance language — a direct descendant of the spoken Latin left behind in the Alpine valleys — today spoken by only a few tens of thousands of people, almost all in the canton of Graubünden. It survives in several regional idioms, brought together in a standard form called <em>Rumantsch Grischun</em>. Naming the processing engine with a Romansh mountain is a small nod to the least-spoken but no-less-Swiss corner of the country.</p> </section> </section> </article> </div> </div> </main> </div> <footer class=md-footer > <div class=md-footer-nav > <nav class="md-footer-nav__inner md-grid"> <a href=REPOSITORIES.html title="Linux package repositories" class="md-flex md-footer-nav__link md-footer-nav__link--prev" rel=prev > <div class="md-flex__cell md-flex__cell--shrink"> <i class="md-icon md-icon--arrow-back md-footer-nav__button"></i> </div> <div class="md-flex__cell md-flex__cell--stretch md-footer-nav__title"> <span class=md-flex__ellipsis > <span class=md-footer-nav__direction > "Previous" </span> Linux package repositories </span> </div> </a> <a href=CHANGELOG.html title=Changelog class="md-flex md-footer-nav__link md-footer-nav__link--next" rel=next > <div class="md-flex__cell md-flex__cell--stretch md-footer-nav__title"><span class=md-flex__ellipsis > <span class=md-footer-nav__direction > "Next" </span> Changelog </span> </div> <div class="md-flex__cell md-flex__cell--shrink"><i class="md-icon md-icon--arrow-forward md-footer-nav__button"></i> </div> </a> </nav> </div> <div class="md-footer-meta md-typeset"> <div class="md-footer-meta__inner md-grid"> <div class=md-footer-copyright > <div class=md-footer-copyright__highlight > © Copyright 2024, Paul Scherrer Institute. </div> Created using <a href="http://www.sphinx-doc.org/">Sphinx</a> 8.1.3. and <a href="https://github.com/bashtage/sphinx-material/">Material for Sphinx</a> </div> </div> </div> </footer> <script src="_static/javascripts/application.js"></script> <script>app.initialize({version: "1.0.4", url: {base: ".."}})</script> |
