Abstract:
In this talk, I will report on two recent results of my work on data processing on modern hardware.

First, I will demonstrate what we can do as a software community to improve the energy efficiency of modern multi-core systems. I will argue that the best energy/performance trade-off can be achieved by bringing the system into a balanced configuration, where the engine’s processing speed matches the memory bandwidth of the platform.

In the second part of my talk, I will show a way how field-programmable gate arrays (FPGAs) can be integrated into Big Data systems. I will present “Rosetta”, which is a compiler to generate FPGA circuits. Rosetta accepts the specification of a language — say, a data format —, together with an action code that describes processing tasks to perform with data in that language. It’s output is a data processor that can run the given processing task in real hardware, often at wire speed. An intended use case of “Rosetta” is the pre-processing of data, e.g., in Big Data systems.
