It isn't necessary for users of the FuzzBench service to know\n+most of these details.\n+\n+- TOC\n+{:toc}\n+\n+---\n+\n+## Overview\n+\n+\n+\n+\n+## Dispatcher\n+\n+As mentioned in the [guide to running an experiment]({{\n+site.baseurl}}/running-your-own-experiment/running-an-experiment/),\n+`run_experiment.py` creates a [Google Compute Engine (GCE)\n+instance](https://cloud.google.com/compute) called the dispatcher to run an\n+experiment. In addition to referring to the instance, \"dispatcher\" can also\n+refer to the [script/process the instance\n+runs](https://github.com/google/fuzzbench/blob/master/experiment/dispatcher.py).\n+The dispatcher (script) doesn't actually do much on its own. It does some\n+basic initialization like saving details about the experiment to the database\n+and then starts four other major components - the builder, the scheduler, the\n+measurer, and the reporter. All of these components run on the dispatcher\n+instance (note that we don't include it in the architecture diagram because of\n+its unique role).\n+\n+## Builder\n+\n+The\n+[builder](https://github.com/google/fuzzbench/blob/master/experiment/builder.py)\n+produces a build for each fuzzer-benchmark\n+pair needed by the experiment and does a coverage build for each benchmark.\n+The builder uses the [Google Cloud Build](https://cloud.google.com/cloud-build)\n+service for building the docker images needed by the experiment since it is\n+faster and simpler than building them on GCE instances. When the builder\n+finishes doing the needed builds, it terminates. Thus, unlike other components,\n+it isn't running for the duration of an experiment.\n+\n+### Builds\n+\n+Details on how builds work are provided in the [guide to adding a new fuzzer]({{\n+site.baseurl}}/getting-started/adding-a-new-fuzzer/) and the [guide to adding a\n+new benchmark]({{ site.baseurl}}/developing-fuzzbench/adding-a-new-benchmark/).\n+Note that we use AddressSanitizer for the benchmark builds of most fuzzers\n+(i.e. all of them support it) so that it will be easier to add support for\n+measuring performance based on crashes.\n+\n+## Scheduler\n+\n+Once the builder has finished, the dispatcher starts the scheduler. The\n+scheduler is responsible for starting and stopping trial runners, which are\n+instances on GCE. The scheduler will continuously try to create instances for\n+trials that haven't run yet. This means that if an experiment requires too many\n+resources from Google Cloud to complete at once, it can still be run anyway\n+after some resources are freed up by trials that have finished running. The\n+scheduler stops trials after they have run for the amount of time specified when\n+[starting the experiment]({{\n+site.baseurl}}/running-your-own-experiment/running-an-experiment/#experiment-configuration-file).\n+The scheduler stops running after all trials finish running.\n+\n+## Trial runners\n+\n+Trial runners are GCE instances that fuzz benchmarks. They start by pulling the\n+docker images that were produced by the [builder](/#Builder) and uploaded to the\n+container registry. Then, from within the container, they run\n+[runner.py](https://github.com/google/fuzzbench/blob/master/experiment/runner.py)\n+which calls the `fuzz` function from the `fuzzer.py` file for the specified\n+fuzzer\n+([example](https://github.com/google/fuzzbench/blob/master/fuzzers/fairfuzz/fuzzer.py)).\n+The runner will also periodically archive the current `output_corpus` and sync\n+it to [Google Cloud Storage](https://cloud.google.com/storage) (this is\n+sometimes referred to as a \"corpus snapshot\"). The runner terminates when it has\n+run the `fuzz` function for the time specified for each trial when [starting the\n+experiment]({{\n+site.baseurl}}/running-your-own-experiment/running-an-experiment/#experiment-configuration-file).\n+\n+## Measurer\n+\n+The role of the\n+[measurer](https://github.com/google/fuzzbench/blob/master/experiment/measurer.py)\n+is to take the output of the trial runners and make it usable for generating\n+reports. To do this, the measurer downloads coverage builds for each benchmark\n+and then continuously downloads corpus snapshots, measures their coverage, and\n+saves the result to the database, a [PostgreSQL](https://www.postgresql.org/)\n+instance running on [Google Cloud SQL](https://cloud.google.com/sql). The\n+measurer terminates when there is no corpus snapshot for this experiment that\n+hasn't been measured. Because the measurer is run on the dispatcher instance, it\n+can't scale with the size of an experiment, so it can actually finish after the\n+experiment is done (usually a few hours after the end of an experiment). The\n+dispatcher instance terminates after the measurer terminates itself.\n+\n+### Coverage builds\n+\n+Running coverage builds does not require any dependencies that aren't available\n+on the dispatcher. One reason for this is because OSS-Fuzz only allows projects\n+(which are used as benchmarks) to install dependencies in the docker container\n+they use for building, and not in the one they use for fuzzing. Therefore, the\n+measurer, doesn't actually use the images from coverage builds, it simply runs\n+the binaries directly on the dispatcher.\n+\n+## Reporter\n+\n+The role of the reporter is to convert coverage (and other data in the future)\n+data output by the measurer into a human consumable report. It runs continuously\n+in a loop while the dispatcher is alive, consuming the coverage data from the\n+SQL database and then outputting an HTML report which it saves to a Google Cloud\n+Storage bucket (which you can access by going to\n+[fuzzbench.com/reports/](https://fuzzbench.com/reports/)).\n" }, { "change_type": "MODIFY", "old_path": "docs/reference/useful_links.md", "new_path": "docs/reference/useful_links.md", "diff": "---\nlayout: default\ntitle: Useful links\n-nav_order: 3\n+nav_order: 4\npermalink: /reference/useful-links/\nparent: Reference\n---\n" } ]
