FIRESTARTER: A Processor Stress Test Utility
[short link to this page: http://tu-dresden.de/zih/firestarter/ ]
FIRESTARTER is a handy utility for infrastructure specialists, thermal engineers, system administrators, and computer scientists that aims at creating near-peak power consumption on standard compute nodes. It can be used for tests of cooling and power infrastructures, system stability test, or as a maximum power consumption baseline for application energy efficiency studies.
While in different research areas tools such as LINPACK and Prime95 are commonly used, these tools are just highly optimized and compute intense routines that solve specific computational problems. As stress test utilities they are unnecessarily hard to use and in many cases unreliable in terms of power consumption maximization. FIRESTARTER is a simple yet versatile Open Source tool that reliably exceeds the power consumption of other stress tests and creates very steady power consumption patterns.
FIRESTARTER is currently only available for the Linux operating system. It currently supports Intel x86_64 processors (optimized since the Nehalem generation), AMD processors (optimized since the Bulldozer 15h family), and NVIDIA and Intel GPUs. FIRESTARTER stresses the most important power consumers of compute nodes: CPU (cores + uncore componenents such as caches), GPUs, and main memory.
Since version 2.0, FIRESTARTER also features an automatic tuning option that allows you to create an optimized version for your specific x86_64 system and its particular combination of core count, frequency, and memory bandwidth using evolutionary algorithms and integrated measurements of power and other metrics.

Unless stated otherwise, we deactivate the turbo mode for all measurements. On processors with a reduced base frequency for AVX workloads, turbo peaks can also occur at nominal frequency. In this case we report the average sustained power consumption after this peak.
