Benchmark configuration parameters can be easily cached and reloaded, significantly reducing benchmark execution time.Noise tolerance has been made a per-benchmark configuration parameter.A variety of simple estimators are supported, and the user can pick which one to use for regression detection.This means that subsequent experiments are performed more consistently, avoiding branching "substrategies" based on small numbers of samples. Benchmark execution parameters are configured separately from the execution of the benchmark itself.BenchmarkTools offers the following solutions to the corresponding issues above: The BenchmarkTools package is a response to these issues, designed by examining user reports and the benchmark data generated by the old system. Using the system in the REPL (for example, to reproduce regressions locally) was often cumbersome.Running benchmarks took a long time - an order of magnitude longer than theoretically necessary for many functions.Different benchmarks have different noise tolerances, but there was no way to tune this parameter on a per-benchmark basis.The estimates used to characterize benchmark results and to detect regressions were statistically vulnerable to noise (i.e.Individual sample noise could significantly change the execution strategy used to collect further samples.It soon became apparent that the system suffered from a variety of issues: Under the hood, BenchmarkTrackers relied on Benchmarks for actual benchmark execution.įor a while, the Benchmarks + BenchmarkTrackers system was used for automated performance testing of Julia's Base library. The Benchmarks package implemented an execution strategy for collecting and summarizing individual benchmark results, while BenchmarkTrackers implemented a framework for organizing, running, and determining regressions of groups of benchmarks. You will see a graphical representation similar to the following screenshot.
big or little endian, high-end or low-end processor). To run the stress test enter the s-tui command into your terminal, then press the down arrow (or j key) and press enter to switch from monitor mode to stress mode. CoreMark is not system dependent, so it functions the same regardless of the platform (e.g. Our story begins with two packages, "Benchmarks" and "BenchmarkTrackers". CoreMark is a simple, yet sophisticated, benchmark that tests the functionality of a microctronoller (MCU) or central processing unit (CPU).
As described in the manual, the BenchmarkTools package supports many other features, both for additional output and for more fine-grained control over the benchmarking process.
