Topic: [XPM] BFGMiner Branch.. on github (Read 9028 times)
very awesome - I have this running on my systems now - will let folks know asap if this works
any news on the bfgminer?
I ported Chemisist's optimizations, and fixed a nasty bug making it do the same work over and over.Working very well on unmodified primecoind testnet-in-a-box now.
also i found several blocks on testnet so it works

We maybe going at this from the wrong angle.
Luke Jr claims that BfgMiner has a 10-20x mining performance improvement over primecoind. If that is really true, it seems like most of the performance improvement should be in the prime implementation since both programs use CPU mining.
It should be feasible to take the prime implementation from BfgMiner and incorporate that into primecoind to get a similar performance improvement out of primecoind and avoid the getwork/gbt issue altogether...
Trouble with that is pools are going tobe needed sooner or later Luke Jr claims that BfgMiner has a 10-20x mining performance improvement over primecoind.

well whoever figures this out gets a 2.5BTC bounty + I'm going to throw in some BTC as well if the improvement is indeed 10x
Client node has no API support yet. Feel free to propose an API format for e.g. getwork.
Based on the above quote from Sunny King, it seems that the client simply has no API support for miners at all at the moment.
I think that needs to be done first before any miner program, BFGMiner or otherwise, can mine Primecoins... Or am I missing something here?
Not quite sure.
I know getwork gives no valuable information:
Code:
{
"midstate" : "7601d3f08f8dd8ac7a67141fa7f24493c6839606ecaf82c6a62a00ad3636923a",
"data" : "000000029ff9bbfa7b85551842ecb1e786bea0b096f92916652235784277e741ee56291e05e3040e4aa68f7c4a2d3f2a91252ad22b25c4799dc88e67f29884a3aee5927751e026a307e7ea1e00000000000000800000000000000000000000000000000000000000000000000000000000000000000000000000000080020000",
"hash1" : "00000000000000000000000000000000000000000000000000000000000000000000008000000000000000000000000000000000000000000000000000010000",
"target" : "000000001eea6700000000000000000000000000000000000000000000000000"
}Blocktemplate also appears to be missing some key information:
Code:
{
"version" : 2,
"previousblockhash" : "f104ee5b36efa6e6d1127306a14c7fe76253a3baaacba3504100533ae016d237",
"transactions" : [
],
"coinbaseaux" : {
"flags" : "062f503253482f"
},
"coinbasevalue" : 1588000000,
"target" : "000000000000000000000000000000000000000000000000006e439100000000",
"mintime" : 1373627219,
"mutable" : [
"time",
"transactions",
"prevblock"
],
"noncerange" : "00000000ffffffff",
"sigoplimit" : 20000,
"sizelimit" : 1000000,
"curtime" : 1373644465,
"bits" : "07ee4391",
"height" : 20203
}
So it appears that either of the interfaces is missing the prime information.

BFGMiner prime is definitely using getwork when talking to primecoind.
I'm still poking around the source code to see if there is anyway to force it to use GBT.

--no-getwork or is that to obvious?
I tried that as well, and while bfgminer does not fail for me, it will not connect to primecoind with the --no-getwork option.
I think there is a problem with blkmk_address_to_script function in libblkmaker/base58.c
I added case 23 and 83 (primecoin PUBKEY_ADDRESS and SCRIPT_ADDRESS), but after 4 hours I have got no blocks ...

This code isn't working "as-is". We are still trying to figure out how to get it working.
GBT, on the other hand, works fine without primecoind modification.
