Key Scoring Principles
Basic scoring principles used for the contest entries judging are described at the official rules page. Here is a short summary: each contest entry was scored according to the following criteria: 1) up to 100 points for solutions performance (speed); 2) a maximum of 25 bonus points for a contestants activity in the forum, calculated as 5 bonus points for each valid forum post/reply.
Post-mortem
I'm creating this thread to organize the post-mortem analysis of the Running Numbers problem. Please put any new post-mortems here. If you want to go over Maze of Life and Consecutive Primes, please create similar threads in their respective forums.
Several contestants have already put their post-mortems in another thread. I will include them here by reference:
It's been fun
The past nine weeks have been fun, educational, and a lot of hard work! I'm glad I got to know some of you here on the contest forums.
I signed up for the Apprentice Level to learn more about multi-threaded programming. Well... mission accomplished. This third problem also taught me the finer points of SSE, which was something I'd been meaning to learn.

Just a reminder: Apprentice Problem 3, Running Numbers, closes on Monday, June 27, 2011 at 12:00 PM (Pacific Daylight Time). Don't forget to upload your entries by the deadline. Also, it is recommended that you zip your files into a zip file and include a text message on the programming language used and any compiling instructions. Good coding!
__m128i type
I am having an issue with the compilation in the MTL. I am using MSVC++ in home and I have a linux MTL account, so I am implementing my solutions in a portable way. For this problem I think that using SIMD instructions is the right choice, so I am using the __m128i type.
Get Bonus Points for Your Threading Challenge entry scores by participating in the Forums
Just a reminder: You can get bonus points added to your problem entry score by participating in each problem's forum. Earn 5 points for each forum post, up to a maximum of 25 points per problem. The forum points can make a difference in your final entry score. So, take advantage of this for this last problem.
Input/Output clarification
This is my understanding of the input and output descriptions:
- The input consists of three command line arguments, each of which is exactly 32 hex digits long.
- The output should be something like "574395734 cycles" printed to stdout.
- The program need not specify if it terminated due to all zeros or repeating the initial values.
- Elapsed time and units (seconds or milliseconds) should be printed to stderr.
Are any of these inferences wrong?
