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
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.
VIXL is dynamic code generation toolkit for ARMv8 that we hope will enable JIT creators to rapidly target the ARM instruction set.
some of the pitfalls and time-sinks involved in creating a good JIT compiler backend. This led us to develop some tools to help improve our productivity. With ARM announcing the new Cortex-A range of processors supporting the AArch64 execution state we decided that we would focus our efforts on A64 tooling to enable developers to rapidly port programming language virtual machines for this new processor range. Soon after we decided to support Aarch32 as well.
This presentation will introduce you to what VIXL is, what’s new in VIXL and how to use it and take advantage of all its components that cover all the aspects of software development on ARM CPUs.
