A175  "run" refers to a session of chrome, visiting several pages and thus176  comprising a browser process and at least one renderer process. A "dump"177  refers to the instrumentation in chrome writing out offsets of instrumented178  functions. There may be several dumps per run, for example one describing179  chrome startup and a second describing steady-state page interaction. Each180  process in a run produces one file per dump.181  These dump files have a timestamp of the dump time. Each process produces its182  own timestamp, but the dumps from each process occur very near in time to each183  other (< 1 second). If there are several dumps per run, each set of dumps is184  marked by a "phase" in the filename which is consistent across processes. For185  example the dump for the startup could be phase 0 and then the steady-state186  would be labeled phase 1.187  We assume the files are named like *-TIMESTAMP.SUFFIX_PHASE, where TIMESTAMP188  is in nanoseconds, SUFFIX is string without dashes, PHASE is an integer189  numbering the phases as 0, 1, 2..., and the only dot is the one between190  TIMESTAMP and SUFFIX.

These files are merged together to produce194    a single dump without regard for browser versus renderer methods.195  * Several phases of dumps from a single run. Files are grouped by phase as196    described above.197  * Several phases of dumps from multiple runs from a set of telemetry198    benchmarks. The timestamp is used to distinguish each run because each199    benchmark takes < 10 seconds to run but there are > 50 seconds of setup200    time.
