11:45 – ScaleMark: Understanding Performance Results for Servers in the Data Center
Speaker: Markus Levy, EEMBC President and CEO
Abstract; Workloads for the Cloud and associated data centers are putting unique demands on the SoCs and other system-level hardware that are being integrated into these scale-out servers. Traditional benchmarks, such as EEMBC® CoreMark®, SPECInt® 2006 and SPECFP® 2006, and others, address the compute complexity of different workloads and the suitability of processors for different tasks. However, when looking at the system level (which is required for comprehending the performance of servers in data centers), many factors contribute to the performance of the system as a whole – memory, disks, operating system, network interfaces, network stack, and more. In addition, the manner in which workloads are generated can significantly affect the results. In this session, using a case study from Cavium’s ARM based Thunder X system and the EEMBC ScaleMark (a cloud and server benchmark suite), results will be presented that demonstrate how subtle variations in the test environment can obfuscate benchmark results and how a properly designed benchmark suite can overcome these obstacles
Android doesn’t give application access to hardware over bus interfacing APIs like I2C, SPI, GPIO, UART, etc. This is going to change in future as Android apps needs to work with multiple different devices like sensors, controllers, etc directly to meet the efficiency and speed required. In this presentation we will introduce the APIs, architecture design and a working demo.
VLAND is a project to enable dynamic network configuration of various switches. A communication protocol to interact with the daemon will be integrated into Linaro’s Automated Validation Architecture so that jobs can dynamically configure the network for testing. In this session, we will review the current state of the project, next steps, and open it up for a discussion.
