To all of you who have participated in Google Code Jam this year and have qualified in 1A / are going to qualify in 1B or 1C for round 2, please keep in mind that you have also qualified for Distributed Code Jam (first round on 14th May). It is an unconventional contest where relatively trivial problems are made interesting by scaling up the problem size and distributing it over mutiple systems. Read more about it here : https://code.google.com/codejam/resources/quickstart-guide
No CodeJam rounds clash with Distributed Code Jam rounds. Also, no registration is required apart from Code Jam qualification. Here's the schedule : https://code.google.com/codejam/schedule
