If you have any good anecdotes, quotes, stories, or pictures of the contest at your site, please send them to Greg Hamerly.
We had 730 teams submit something. There were 665 teams that solved at least one problem. There were 8395 submissions during the 5 hours, an average of almost 1 submission every 2 seconds, and an average of 11.5 submissions per submitting team.
Here are the limits used on the contest judge server. Note that the limits are tuned for the server, and on different hardware other limits may be more appropriate. All problems had a memory limit of 2048 MB.

Details about the qualifying contest and the practice are being sent by email to all coaches who have registered teams. The emails are from firstname.lastname@example.org to the registered coaches. Please watch for the email (and check your spam filter).
The emails contain the information each team needs to login to the Kattis system. The passwords will be different for the practice and actual contests.
The account information for Kattis was attached to the email as a tab-delimited file, with one entry for each team registered to the coach.
The contest begins at 2:00 PM CDT on Saturday, Sept. 29 2012, and lasts for 5 hours. The start time in other timezones are here.
Registration and team changes are now closed. No more teams will be added or permitted to change. However, as long as you registered a team (even if it has no contestants) you will receive a Kattis login (by email, see above) which you can use for the contest. Note that Kattis only knows about teams, but the ICPC registration system (which is totally separate) knows about individual contestants.
The practice contest started at 18:00 UTC on Monday September 24th 2012, and will finish at the same time on Friday September 28th. You can log in to Kattis (with your account information sent by email) here: https://icpc-qual-12.contest.scrool.se/
There is a public scoreboard serving individual results specific to each institution (you can select your institution from the drop-down menu).
To participate in the contest, each team will need an internet-connected computer to submit their code. The computer does not need to install any special software (e.g. we are not using PC^2). The teams will use a web browser to log in to Kattis using their Kattis credentials (which will be sent by email, see above). Kattis is the contest control system, used to submit code and clarifications, receive judgments, view problem statements, etc.
Problem statements are available here.
This contest scoring system will be the same as the world finals. That is, the winner is the team solving the most problems. If two teams solve the same number of problems, then the team with the lowest time is the winner. If two teams have the same time the submission time of the last solved problem is used as a tie-breaker.
The time is the sum of the time of submission (in minutes) of the earliest correct submission for each solved problem, plus any penalty minutes for each incorrect submission of a problem prior to solving that problem. Penalties are 20 minutes for any of the following reasons (described here: https://icpc-qual-12.contest.scrool.se/doc/judgements):

To register for the qualifier, please go through the normal registration process at icpc.baylor.edu. For registration reasons, there are 11 qualifying contests -- one per North American region. In reality, they will all be the same contest. You should register for the contest in your region.

Each region's contest has two 'sites': one for ICPC-eligible teams, and one for 'other' teams. Most teams should register for the ICPC-eligible site. The 'other' site is intended for teams whose contestants are not ICPC eligible, such as high school students, or people whose ICPC eligibility has expired.
Around the time that registration closes, we will send out an email with information about the practice contest. We intend to leave the practice contest open for the entire week prior to the competition.
Our intention is certainly not to create another level or hoop for students to jump through; as stated in the original invitation the results are for local coaches to use as they please.
Using our contest has several advantages: less work on your part to put on a local contest, broadened participation for those who haven't had the chance to offer a qualifier in the past, more student registration helps your region's allocation of wildcard slots for the world finals, and all students who participate in the qualifier receive a free year of ACM student membership automatically.
We will not be using PC2; we will use Kattis. This will require minimal software setup on your part (internet connection, web browser, development environment(s)).
At this time we are planning support for C/C++/Java. Other languages may be supported, but no promises.
We will offer one set of questions, but hope that they will span a difficulty range that is wide enough to accommodate novices and advanced students.
