miniBachelor

Diese Mini-Code-Version meiner Bachelorarbeit dient mit ca. 370 Code-Zeilen als Beispiel des Farmer-Worker-Modells. Der C++ Code zeigt die Nutzung von Apache Thrift (zur Verteilung) und glpk (zum Lösen).

Der Code besteht im Kern aus folgenden Dateien:

- MiniBachelor.thrift: ca. 20 Zeilen IDL beschreibt den Teil, der für Farmer und Worker wichtig ist
- Farmer.cpp, Worker.cpp: ca. 200 bzw. 120 Zeilen enthalten die Implementierung.
- farmer.conf: praktisch, um nicht alle Konfigurationsdaten in der Komandozeile angeben zu müssen
- Buffer.hpp: Mit ca. 30 Zeilen Code ist dies eine Klasse, wo Threads Elemente entnehmen und beifügen können. Dieser Vorgang wird durch Semaphoren geschützt.

Im Branch "speedup" habe ich mit jedem Commit folgende Features beigefügt:

- Worker-Proxies mit gerader id machen Breitensuche
- Optimierungen beim Kompilieren
- Nutzung einer Heuristik statt Simplex
- Multi-Threaded Server und Callback-Funktion zum Beenden von solve()
