SSE4.1

I'll put up one Bitcoin in bounty for a CPU-miner (standalone) that will run on both windows and linux and outperform the built-in miner.
Recompile the existing one with some more optimization flags or with the ICC compiler. 
Existing one as in the one built into the primecoin wallet? I haven't dug into the source code yet, but I'm interested in the support for shares and such.

AVX/SSE3 enhanced miner would be nice...and/or gpu.

Problem is it would be hard to compare, I plan on getting two identical machines, running them side-by-side, and every 2 minutes asking each for their hashrate, then averaging it over a 6-hour period.
The primespersec measure is for fun only, it does not necessarily reflect true mining performance. The only accurate measure is block rate, that is, given a fixed difficulty how fast can you generate blocks. To measure this one can use a lower difficulty than the network difficulty.

How do you know if your block that you mined is orphaned or not?

How much does it need to outperform it?I'm looking into possibly adding support to BFGMiner.

Hell, 20%? Adding it to BFGMiner would be awesome

Shouldn't be hard to beat my built-in miner, it was meant to be a basic reference miner and I could be missing quite a bit of simple optimizations.
For example it currently uses an adaptive primorial multiplier which is quite wasteful as I don't have a good understanding of the relationship between the size of primorial multiplier and mining performance.

RPCport for client?

since primespersec doesn't seem to have comparable meaning, it would be difficult to compare performance. Maybe primespersec could be normalized to the size of the primes and to the length of the chain?

How long till blocks mature?

Finally mined 19.47XPM on my i3 2120 with only 1 core.

The prime chain of each block is built starting from its hash (in a way) so you cannot simply compute any chain in advance.

I see, thanks.
Just noticed that there is a lot of info on this that I missed.

Gentoo ebuild of the daemon here, for the true believers. Modified from bitcoind 0.8.2 ebuild.

https://github.com/teknohog/ebuilds/tree/master/net-p2p/primecoind
Any guide on how to use it?
