Beim Programmieren von Computern geht es darum, Datenbits zu verschieben und sie auf bestimmte Weise umzuwandeln, um ein bestimmtes Ergebnis zu erzielen. Diese Vorgänge sind jedoch mit einem Zeitaufwand verbunden. Deshalb kann man sich Hochleistungsprogrammierung so vorstellen, dass man diese Vorgänge minimiert, indem man entweder den Overhead reduziert (d. h. effizienteren Code schreibt) oder die Art und Weise, wie wir diese Vorgänge ausführen, so verändert, dass jeder einzelne sinnvoller ist (d. h. einen geeigneteren Algorithmus findet).
Konzentrieren wir uns darauf, den Overhead im Code zu reduzieren, um mehr Einblick in die tatsächliche Hardware zu erhalten, auf der wir diese Bits bewegen. Das mag wie eine sinnlose Übung erscheinen, da Python die direkte Interaktion mit der Hardware so gut wie möglich ausblendet. Wenn du jedoch verstehst, wie Bits in der realen Hardware am besten bewegt werden können und wie die ...
