Oberseminar System- und Rechnerarchitektur (OSRA)

Inhalt

Im Rahmen des Oberseminars werden im Wechsel wissenschaftliche Grundlangen erarbeitet sowie die eigenen Projekte im Rahmen der Bachelorarbeit, Masterarbeit oder Dissertation präsentiert und diskutiert.

Das Oberseminar richtet sich vorrangig an studentische Arbeiter und Doktoranden am SRA. Eine Teilnahme für andere Mitglieder der Universität ist auf Nachfrage möglich.

Leseliste zum Thema Betriebssystemkern-Paradigmen

Grundlagen – Mikrokerne

Mit MACH [1] begann das Mikrokernfieber, auch wenn die Idee des message-passing kernels schon auf Brinch Hansen's RC 4000 Betriebssystem [2] zurück geht. Problem war immer die IPC-Performance. Damit räumte erst L4 auf [3, 4], das durch ein hohes Maß an (hardwarezentrierter) Spezialisierung konkurrenzfähige Performancewerte erreichte [5].

Für den Beginn sei zunächst die Lekture von [1, 4, 3] (in dieser Reihenfolge) empfohlen:

Grundlagen – exokern

Der exokern [11] begründet die Philosophie des Verlagerns von Betriebssystemfunktionalität in die Anwendung (bzw. Bibliotheken, die mit der Anwendung gelinkt werden) – und damit der anwendungsgewahren Spezialiserung.

Die Lekture von [11] ist schlicht ein "Muss":

Neuere Ansätze – Die Multicore Challenge

Neue Ideen scheinen in der Betriebssystemwelt in Wellen zu kommen. Nachdem lange kaum noch neue Ansätze zum Kerneldesign vorgestellt wurden, kamen 15 Jahre später mehrere Ideen zum Umgang mit massiver Parallelität im Betriebssystemkern und der Verfügbarkeit einer großen Anzahl von CPUs "auf den Markt". Corey [21] stellt dabei in bester exokern-Tradition das Sharing von (Betriebssystem-)datenstrukturen unter die Kontrolle der Anwendung, so dass diese (in der Regel) nur von einem CPU-Kern bearbeitet werden. Barrelfish [22] verhindert hingegen implizites Sharing vollständig, indem BS-Dienste exklusiv auf einzelne CPU-Kerne verteilt werden und – in bester Mikrokern-Tradition – nur über Nachrichten kommuniziert wird. Einen ähnlichen Weg beschreitet auch fos [24], wobei hier der Paradigmenwechsel von time sharing zu space sharing am deutlichsten wird. Arrakis ist ein fork [25] von Barrelfish, der Anwendungen den direkteren Zugang auf die Hardware gewährleistet – wodurch die Grenze zwischen Mikrokern und exokern weiter verschwimmt. TxOS [23] ist hingegen ein Ansatz für den klassischen Monolithen (Linux), indem syscalls als Transaktionen ausgelegt werden.
