Go to the forum index of problem 2 and hit the 'subscribe' checkbox, it'll email you everytime someone posts, takes the comming back to check every couple of days out of the equation.

I kinda missed that pre-computation post, given i precomputed the enitre range and there was no mention of it in the problem descripton, I'm obviously completly against that rule being enforced.

Then again like last problem if intel decides to do things differently its their contest and do whatever they want. Just saying i'll be throwing a temper tantum stoping my feet going NOT FAIR!!! I DID NOT KNOW! if they enforce it and everybody else is going to stomp their feet saying HE HAS AN UNFAIR ADVANTAGE!! if they don't.

soo yeah great communicating there intel, when you change rules, change the original problem description and email everyone about it, a forum post just doesn't cut it. lets put this on the 'things we learned' list :)

I remember the posts about the precomputed primes, I decided to use a 180 precomputed primes table. I decided the size of the table in a very arbitrary way, but I think that if for fair play Intel wants to put a limit , the valid range of this table should be big. In fact, I would not mind being beaten by a solution with a table five times bigger than mine. I don't know where is the point where the precomputed table size becomes an advantage...

I also do not mind precomputation, as long as the solutions are scored on their ability to thread.

We'll be announcing the Problem 2 winners later this week. I just posted a notice on this. Thanks for being patient.
