    In-Depth Analysis of OLAP Query Performance on Heterogeneous Hardware
    (Datenbank-Spektrum: Vol. 21, No. 2, 2021) Broneske, David; Drewes, Anna; Gurumurthy, Bala; Hajjar, Imad; Pionteck, Thilo; Saake, Gunter
    Classical database systems are now facing the challenge of processing high-volume data feeds at unprecedented rates as efficiently as possible while also minimizing power consumption. Since CPU-only machines hit their limits, co-processors like GPUs and FPGAs are investigated by database system designers for their distinct capabilities. As a result, database systems over heterogeneous processing architectures are on the rise. In order to better understand their potentials and limitations, in-depth performance analyses are vital. This paper provides interesting performance data by benchmarking a portable operator set for column-based systems on CPU, GPU, and FPGA – all available processing devices within the same system. We consider TPC‑H query Q6 and additionally a hash join to profile the execution across the systems. We show that system memory access and/or buffer management remains the main bottleneck for device integration, and that architecture-specific execution engines and operators offer significantly higher performance.

    Integration dynamisch rekonfigurierbarer Funktionseinheiten in Prozessoren
    (ARCS 2004 – Organic and pervasive computing, 2004) Pionteck, Thilo; Stiefmeier, Thomas; Staake, Thorsten; Kabulepa, Lukusa D.; Glesner, Manfred
    Dieser Beitrag befaßt sich mit der Integration dynamisch rekonfigurierbarer Architekturen als Funktionseinheiten in RISC Prozessoren mit Befehls-Pipeline. Dabei wird insbesondere auf die Organisation der Konfigurationsdaten sowie die Kontrolle des eigentlichen Rekonfigurationsprozesses eingegangen. Es wird eine Architektur vorgeschlagen, welche leicht in eine Vielzahl von Prozessorarchitekturen integriert werden kann, ohne Änderungen an der Pipelinesteuerung vornehmen zu müssen.
