GLaDOS@Home

From Portal 2 ARG Wiki - Valve ARG Network

Jump to: navigation, search

GLaDOS@Home is a spoof of other distributed computing efforts like Folding@Home. The site at http://aperturescience.com/glados@home became live on April 15, 2011 at 9 AM PDT - the time predicted by the Bathysphere puzzle and the Countdown timer from previous ARG steps. The page's stated goal is to reboot GLaDOS, which would take a considerable amount of time to complete (by default, ending on Portal 2's official launch time, April 19 at 7 AM). By using "distributed" resources - Steam users - playing the thirteen games in the Potato Sack, and by collecting the hidden Potatoes within them, players purportedly will be able to reboot GLaDOS earlier, effectively unlocking Portal 2 some time before April 19th.

Potato Idling

At the moment the potato count keeps decreasing from ~63,815 to ~61,815 and then jumps back to ~63,815.

Potato Countdown

On April 18th at 10:50 GLaDOS engaged "starch-based power cells" meaning the CPUs got overclocked which resulted in a faster computation process. The potato count started to drop from around 463,000 at a rate of about 700/min, projecting that they would be depleted in ~9 hours 40 minutes from the start, or 21:00 PST.

How the site works

GLaDOS@Home at about the 50% mark (4/16/11, ~11:30pm PDT)

The red bars next to each video game represent the total time people have played that game for; this fills up over time.

The number under each bar (current CPUs) shows how many people are currently playing that game, and hence the rate it's filling up. [Confirmed via consulting the Steam stats page]. 9 lucky people are already playing Portal 2

The main bar at the top represents the average of the length of all the red bars. Once this is full (when every red bar is full), we get Portal 2!

The potato number at the bottom shows the total number of potatoes that everybody has found. The number is now decreasing as GLaDOS overclocks the CPUs and makes the bars rise faster. If you get all 36 potatoes by the time Portal 2 is out, you also get a special prize.

When a red bar fills up completely, it turns blue. This acts as a checkpoint of sorts, knocking off a guaranteed chunk of time from the release date. This will only matter though if we fail to fill the main bar up in time. Note that once a bar is full up, there is no longer any point playing that game; switch to another.

More popular games require more people in order to fill up at the same rate; it is the proportion of game owners playing a game that matters, not the number of people by itself. [Also confirmed by Doug].

We have word on how the progress bars work from Dougley:

 The individual game progress bars are based on sales made. The more times a certain game has been bought, the more you have to play it to finish its bar.
 For example, 1 2 3 KICK IT! was released at (nearly) the same time as the pack, so it has the fewest sales making it the easiest to complete out of the whole pack.
 Killing Floor and Audiosurf were out for longer and as such have had way more sales, so they require a ton of more hours to complete.
 According to Dougley, Potatoes still matter and are of importance (but don't neglect playing the games). Get them.
 The Store might be keeping a record of how many times a certain game has been bought, so we need to go find that and order which games we should play based off of that.

Tactics

In order of priority;

1. Constantly run a game in the potato sack for as much time as you can (leave it on when you're away from your computer!), preferably one at the top of the priority list below.

2.Collect as many potatoes as you can (guide)


It follows from the above that we should be doing the easiest (least popular) games first. Firstly, this means we get the guaranteed checkpoints. Secondly, and most importantly, by leaving the hardest games until last, we ensure that we have the maximum number of potatoes when we get to that hard game, making things a lot faster.

Priority list

This is based on which games have bars that are easiest to complete, which we should focus on first. If you have the current focus game, play that; if not, the next highest game.

For reasons why we have the priority list, and why we switch before they are complete, see Switching Games Before Completion.

Countdown trackers

See also: Countdown Aids

Here is some data, and some calculators predicting when Portal 2 will be out based on current rates. Bear in mind these might be inaccurate because while GLaDOS reports the guaranteed time that has been "knocked off", these pages produce a time which is an estimation of when we will finish all games (based on current rates). This rate is constant around 10 hours before launch time, which is why Potatos are so important, they are our only hope of releasing it more than 10 hours ahead of schedule.

The story so far

At 17:00 on April 14th, 2011 Audio Clues led to a QR code. It leads to an ApertureScience.com URL with a countdown to 4/15 9:00 AM.

At 09:00 on April 15th, 2011 the countdown page redirects to here, confirming an early release provided enough people log in to Potato Sack games. Track a current estimated completion time here. Note that this is a running estimate based on the current progress rate and not an exact countdown.

At 10:50 PST on April 18th, 2011, new lines of text appeared on the console at the GLaDOS@Home page:

10:50 - Engaging starch-based power cells
11:00 - Reboot safety test protocol initiated...
11:00 - Relaxation chamber locks released...
11:00 - Involuntary hazard mitigation associates have assumed testing positions...
11:00 - Pre-release lethality assessment initiated...

At that time, the potato count started to drop from around 463,000 at a rate of about 700/min, projecting that they would be depleted in ~9 hours 40 minuts from the start, or 21:00 PST.

Theorised formula for timers

This is a Mathematical Theory that attempts to explain how the GlaDOS@Home system calculates the game time.

Assuming that when we reach 100%, Portal 2 is released-

(Not valid since the potatos countdown started)

Auxiliary Power (previously Challenge Status) (The Potato Multiplier)

This email from a member of the team at Valve confirms that the Potatoes act as a multiplier to each user's Man hours. But we need to reach a certain milestone of potatoes for that multiplier to activate. The actual milestone amount, and how much of a multiplier this will give us is unknown. Please update the Wiki with this information when the milestones are achieved.

Possible Overclock Potato Numbers

Theories

Update: The overclocking has started (at about 463,000 potatoes). It's possible that it was always going to trigger at this time, with the amount of potatoes collected at this point being used to determine how long the overclocking would last.

Number of active test subjects

This displays the number of people currently playing Portal 2 (confirmed on Steam Stats page). Originally the page displayed "ZERO". Just ten minutes after the overclocking started it changed to "NINE".
