Presto on ARM – Chunxu Tang & Jiaming Mai, Alluxio

Traditionally, the deployment of Presto has been limited to Intel processors with the x86 architecture. However, with the growing popularity of ARM architecture, Chunxu and Jiaming have extended the Presto ecosystem to ARM and conducted a series of benchmark experiments. Their objective is to evaluate the performance of Presto on ARM architecture and identify key insights from the experiments. In this presentation, Chunxu and Jiaming will share the results of their performance evaluation and discuss some of the most significant findings from their research.
