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. Note that the current dump filename also includes a191 process id which is currently unused.192 This manager supports several configurations of dumps.193 * A single dump from a single run. 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.
