Leistungs- und Energieeffizienz-Analyse für innovative Rechnerarchitekturen
Über die Leistungsfähigkeit von Prozessoren und Systemen hinausgehend zeigt sich seit mehreren Jahren, dass eine weitere wissenschaftliche Schwerpunktsetzung in Bezug auf Energieeffizienz von Rechnersystemen unbedingt erforderlich ist. Die Effizienzsteigerungen durch verbesserte Fertigungsverfahren sinken zunehmend und müssen durch breiter verankerte Maßnahmen verstärkt werden. Hier zeigt sich, dass die Optimierung paralleler Anwendungen hinsichtlich ihrer Energieeffizienz vielversprechend ist – insbesondere durch eine intelligente Steuerung der unterliegenden Hardware durch die wissenschaftlichen Anwendungen.
Einen weiteren Forschungsschwerpunkt hinsichtlich neuartiger Rechnerarchitekturen stellen Hardwarebeschleuniger dar, die inzwischen hauptsächlich durch sogenannte general purpose GPUs (GPGPUs) sowie manycore-Prozessoren vertreten werden. Die Forschungsarbeiten am ZIH auf diesem Gebiet reichen von der detaillierten Untersuchung der Hardware-Beschleuniger über die Bereitstellung von Software-Werkzeugen für die Performance-Analyse bis hin zur Portierung und Optimierung von wissenschaftlichen Anwendungen auf Beschleuniger-Architekturen.
