Nokias, Nokias everywhere…

Aki’s been busy; he’s rounded up 12 more n800/n810 devices, an old guitar pedal board, some velcro and sticky tape. Some firewall hacking, and we’re now seeing our first automated numbers up on staging graph server. My personal favorite details are the custom made stylus holders.

So far the heat from all the power supplies inside the case seems fine, but we’re keeping an eye on it.

This is really exciting progress, but we’ve still got a lot of work to do here.

Normal Talos runs do a lot of work to reduce noise and machine variance in the test results; we do a total of 15 iterations of the same test; (5 iterations on each of three separate machines). On these *slow* mobile devices, *one* iteration takes approximately 3 hours; good enough for us to check infrastructure is in place, but too noisy to be usable by developer – thats the results now visible on staging graphs above. Doing 5 iterations, like we do for PCs, would take 15 hours. Ideas we are investigating are:

  • having multiple sets of devices running at staggered different times (one different set running every 8 hours, for example). We weren’t able to do this for PC builds because there was too much machine variance noise in the results, but maybe the ongoing rebootabilty work might finally solve that.
  • only have one set of slaves running, but always test the latest pending build (skipping over other builds in the process). This avoids the machine variance noise, but would still peak out at one talos run every 15 hours, and if you miss that, you’d have to wait for the next 15 hour cycle to come around.

We’d like to be able to do more frequent runs if at all possible…any/all suggestions welcome! 🙂
