Die Art und Weise, wie wir heutzutage das Internet verwenden, hat einen enormen ökonomischen Einfluss auf den Energieverbrauch unserer modernen Gesellschaft. Nimmt man zum Beispiel alle Server des Internets zusammen und berechnet Ihren Stromverbrauch, dann kommt man auf eine Zahl, die ungefähr 2% des jährlichen Stromverbrauchs der USA und ca. 26% des Gesamtenergieverbrauchs in Deutschland entspricht. Die Mission des Sonderforschungsbereichs „Hochadaptive Energieeffiziente Systeme“ (HAEC) ist es daher hochgradig energieeffiziente Systeme für unsere moderne IT Infrastruktur zu entwickeln, ohne dabei auf das Leistungspotential dieser Systeme zu verzichten.
Natürlich wäre es ein einfacher Weg den Energieverbrauch jeder einzelnen Systemkomponente zu minimieren. Allerdings arbeiten die meisten Hard- und Softwarekomponenten heute schon auf ihrem Energie/Leistungsoptimum. Zielführender ist es daher ein generelles Verständnis dafür zu entwickeln, wie Software auf Hardwarekomponenten angepasst werden kann und umgekehrt, wie sich Hardwarekomponenten an den schwankenden Ressourcenbedarf der Software anpassen können. Für eine solche Anpassung sind neue Methoden und Werkzeuge nötig, die es Programmierern erlauben energiebewusste Software zu entwickeln. Neue Interaktions- und Kommunikationslösungen werden gebraucht, die eine Vielzahl an Softwarekomponenten auf einem hochgradig parallelen System unterstützten. Mit anderen Worten, wir brauchen einen neuen integrierten Ansatz zur Entwicklung hochadaptiver energieeffizienter Systeme, der alle Ebenen moderner Systeme umfasst.
Der Sonderforschungsbereich HAEC ist ein erster Versuch eines solchen integrativen Ansatzes. Auf Schaltkreisebene versuchen wir innovative Ideen für optische und kabellose Chip zu Chip Kommunikationsmedien zu entwickeln. In der nächsthöheren Netzwerkschicht erforschen wir sichere Hochleistungskodierungsschemata für Netzwerkströme. Kontroll- und Koordinierungslösungen werden untersucht, um die Anpassung der Hardware- und Softwarekomponenten zu steuern. Neue Techniken zur Softwareentwicklung werden durch energiebewusste Ausführungsumgebungen bereitgestellt, die eng mit den Ressourcen-, Strom- und Konfigurationsmanagement Algorithmen auf Betriebssystem -und Anwendungsebene zusammenspielen und neue Internet Applikationen werden durch energiebewusste Dienste ermöglicht. Darüber hinaus erforschen wir formale Methoden, die in der Lage sein werden, ein neues Level an Vertrauen in die entwickelten Systeme zu liefern, da sie die Einhaltung von Garantien formal beweisen können. Unser Ziel ist es die Ergebnisse all diese Entwicklungen in einem Prototypen zu demonstrieren – der HAEC Box – und somit die antreibende Kraft hinter der akademischen und industriellen Entwicklung zukünftiger energieeffizienter Systeme zu werden.
