Accelerating Cosmological Data Analysis with FPGAs

The performance improvements of the FPGA implementation of a common cosmological data analysis algorithm in DIME-C are shown to be in a good agreement with the predictions of the Reconfigurable Computing Amenability test.

Abstract

We present an implementation of a common cosmological data analysis algorithm in DIME-C for the Nallatech H101 FPGA accelerator board. We apply the Reconfigurable Computing Amenability test to investigate the suitability of FPGAs for accelerating this algorithm. We present a parallelization strategy for the FPGA implementation of the algorithm and discuss its realization in DIME-C. The performance improvements of our FPGA implementation are shown to be in a good agreement with the predictions of the Reconfigurable Computing Amenability test.
