edit: where is the source code ?

I am not in the business of making cpu mining software, really.

agran, the sourcecode repo you pointed out is the wallet software. I think it's better to start with some cpuminer fork (either pooler's or Jeff Garzik's).
If any mining pools are offering cpuminer binaries based on one of these two, you can just ask for the source code (GPL requirement!)

the wallet can only solo mine, and that may become pointless at some time. So any CPU optimizations in the wallet would be pointless too.

Guys, to optimize cpu miners use a midstate approach.

You can put the block header's first 80 bytes (including nonce) into the sph_fugue256() function
and all that changes between hashes in the sph_fugue256_context is the ctx_fugue.partial field
which is nonce in big endian notation.

Duh, so precompute state once per scanhash call - all remaining work is done in
sph_fugue256_close() run inside the scan loop. instant 5x speed gain.

My Phenom II X6 got 2.5 MHash/s out of this on 6 cores.

It's a low hanging fruit really.

Next, address SSE2 or AVX vectorization and get close to 5-10 MHash/s.

Hmm... can you compile a windows x64 binary for us/me please Huh

Thank!

where is?

this brief posting is all you will get from me Wink

I'll leave it to others to optimize the CPU miners.

Is anyone else having a issue getting minerd working on windows8? I'm running 32 bit, that is probably the problem.

Well i missed the boat on this one.

Yeah, I missed it, too. I wish I got into to this coin in the early days. Same with Bitcoin. I wish I started there a few years earlier...

These days the "early days" for new coins is basically the first 5-10 minutes

Well i missed the boat on this one. I stuck 8320's in my mining rigs specifically for the purposes of CPU mining, but everything gets raped by the VPS miners and botnets, and the secret GPU miners of course. Even good old scypt coins getting tougher and tougher to mine with these massive GPU farms and now scrypt ASICs here. I remember the days when my 4200 khs made me one of the top dogs on most new coins. Sure we got scrypt-jane and a bunch of other GPU only algos, but eventually investors will stop caring that we want our mining rigs to continue being profitable and see through the facade of "decentralization!!! GPU mining forever!!".

Don't mind me, just been here a year (which is still nothing compared to some of these guys) and reminiscing on "the good 'ole days".

Anyway, thanks for giving my 8320's something to do for a while. Hopefully I scoop up a couple hundred at least before the difficulty hits 1000.

Is this minerd for the pool only for windows or can the regular linux minerd work if we point it to

minerd -a fugue -o stratum+tcp://fc.minepool.cc:10029 -u WORKER -p PASSWORD --threads=THREADS

?

The pool does not work and the difficulty increase a lot...

This coin will die and nobody will want to mine it if that continue like it.

Pool works like a charm. Be sure you use right address http://fc.minepool.cc:81/

how do you use minerd with the pool. it doesnt work
