First coin found with this miner: http://puu.sh/3CdP6.png 3 minutes ago EST

So he checked the code in and released this an hour ago, and its show you mined that coin yesterday..how is that possible?

Found any blocks?

you think somebody after a mins of the release found a block very easy. i have more than 24 hrs before this release @900pps and not found nothing, give more than 3 hrs for check this

I sure hope this was tested before released.

It's likely folks will still find blocks with it, but without running on testnet for a few hours and comparing the results to another build it won't tell us much. Just reduce the prime sieve size on Sunny's client, boom your PPS goes through the roof.

Well, to be honest, I was slightly concerned about changing the sieve size. I'm not 100% sure about the full effects. What I do know is that when you reduce it to 100,000 you stop getting millions of L1 write misses.

I have found quite a lot of blocks on mainnet with the reduced sieve size. I will try to get some better comparison numbers on testnet.

Installing the libgmp-dev package should fix that.

Doesn't reducing the sieve size reduce the likelihood you'll find a solution by the same amount you've increased the primes per second?

Can you compare the number of blocks found with your code versus sunny's code on the test net per some time interval?  As sunny has said multiple times, the pps rate is not an effective measure of block finding increase.

I believe that has to do with the fact that the PPS varies widely ... this is a dramatic increase on each cpu, i think when PPS is "generally high" or "generally low" is what sunny meant.

Here is my high performance version of Sunny King's Primecoin client. This version improves mining performance significantly.

Notable changes:
 * Use GMP for bignum calculations in the mining threads
 * Reduced sieve size to 100,000 so that important arrays fit into L1 cache
 * Replaced some bignum calculations with 64-bit arithmetic inside the sieve
 * Reduced the amount of memory allocations
