Introduction
Arm technology now powers a broad spectrum of on-premises and cloud server workloads. Building on Ampere Computing’s previous reference architecture, which demonstrated that Apache Spark on Ampere Altra – 128C (Ampere Altra 128 Cores) processors delivers superior performance per rack, lower power consumption, and optimized CapEx and OpEx, this paper evaluates and extends that analysis to showcase Spark performance on the latest generation of AmpereOne® M processors.
Scope and Audience
This document describes the process of setting up, tuning, and evaluating Spark performance using a testbed powered by AmpereOne® M processors. It includes a comparative analysis of the performance benefits of the 12-channel AmpereOne® M processors relative to their predecessors, specifically Ampere Altra – 128C processors. Additionally, the paper examines the Spark performance improvements achieved by using a 64KB page-size kernel over standard 4KB page-size kernels.
