Actually, that makes 3-4 pools.

There is also http://mpos.imacredit.org and http://www.multicoinpool.org.  Stratum ports on the website (http://www.imacredit.org/coin-details.html)

FYI - most pool software really sucks are reporting low hashrates that are the nature of IMA Credit.  One of the devs is going to try and get mpos.imacredit.org reporting in Hash instead of KHash later today.  Wish him luck!

I believe HashHarder also spun up a pool, but don't know much about that one.

Well, good news and bad news.

Good news:  Your GTX is doing fine.

Bad news:  after an evening or three of testing, we can confirm that --algo=scrypt:131072 is required, although we have no idea why.  That should be the parameter for a N-17 coin.  If you use scrypt:65536 (which is what we expected) the miner will hash, but all blocks were rejected.  This was previously reported and is now confirmed.  Alas, that is what I was using with Cudaminer in my previous reports so my 560Ti numbers were double what they should have been.

Our best guess is that there is an additional 63 byte wrapper associated with the scratchpad space, meaning scrypt:65599 might work, if the code accepted that value, which it doesn't...

Just do the math.  256 seconds per block * 16 coins/block = ~2M coins a year.  Are you really concerned about coins found 46,640 years from now?  If not, there are 2M coins available over the next 12 months - go get some.

If variance is a concern, we should have a pool up soon (e.g. tonight?  maybe... a day or three is more likely).

Otherwise is the standard luck-of-the-draw, but I tell people to think in terms of blocks per week vs. per minute.  E.g.  Let it run for a few days and see.

Thank you C-Cex!!!

We haven't found a GPU miner yet that can handle that N.  Most appear to allocate the hash scratchpad from the stack instead of the heap and die with stack overflows.  Good news: that is fairly easily fixed by the code writers if they wish to do so.  Bad news:  we are waiting for it to happen for some someone to find a branch that works.

When they do, I'll post, since I have half a dozen GPUs I'd like to point at it.

Good time to point out that midrange GPUs are hashing at, ballpark, the same speed as CPUs.  e.g.  My GTX 560 Ti is doing about 90hashes/sec which straddles various CPUs I have running (40-120 hashes/sec).

Cassey

Yeah, we lost somebody.  We need about 5K to reach critical mass.

Remember that you can't measure that hashrate vs. any other coin, at least not unless they are also N=16.

Good news, it looks like we will have a pool or two within a few days for those that want less variance.  Maximum mining results will still occur only if you solo mine, since the pool will have some overhead.

Still talking with Poloniex and C-Cex as well.

Presuming you built if off another kernel, and didn't write it from scratch without reference to any public domain opensource software - by the license agreement associated with that public domain base/reference software your code must be made public domain.  That is how open-source works...

Ah, sorry, was looking for a CPUMiner (aka. Minerd) current windows build, not a Cudaminer build.  Have that and its working fine against my NVidia card.

Not yet, but its being discussed with Poloniex and C-Cex.

Yeah, I made one pass using my coin developer box where I build the Windows wallets, but the MinGW environment isn't quite right for building minerd and I would hate to screw it up and break things.  Took me several months of playing to get it working for coin building...

set worker=<rpcusername>
set pass=<rpcpassword>
set opts=--algo=scrypt:131072 -lf5x7 -L6
set url1=http://127.0.0.1:9332
set s1=-o %url1% -O %worker%:%pass%

cd x64

cudaminer %opts% %s1%

Works fine on older NVidia.  Use -lt5x7 for Titan class NVidia.

Anybody have a link to a Windows 2.4 version with scrypt:131072 support in it?

I have it running on about 7 Linux boxes just fine, but the 2.4 Windows version from Sourceforge generates:

minerd: unknown algorithm -- 'scrypt:131072'

For reference:

minerd -V
cpuminer 2.4
 built on May 20 2014
 features: x86_64 SSE2 AVX AVX2 XOP
libcurl/7.34.0 zlib/1.2.8

Should I encode a world peace algo as well?  With complete freedom and prosperity for all, no government controls, and everyone will be nice to everyone and never take advantage of the gullible.  Everyone would, of course, WANT to work full time jobs and will happily do so whether that is flipping burgers or doing robotic design, because that will be the right thing to do for society.  We can build home that will last 1000 years, out of rock, so there won't need to be fire department, and safety will be improved.  Very sustainable.

Short form:  Have a real suggestion?

We are in discussions with C-Cex and Poloniex right now.  One advantage of being an established developer is that both exchanges currently list one or more of my other coins.  With a bit of luck, we should be up on one or both in a week or two.  Maybe.  Can't promise something I don't control.

All great news.  It was my hope that GPUs would perform at about the same rate as CPUs.  Perhaps 5-10X faster, but not 200X like on Scrypt.  Seems we are close.

This, of course, leads us to the question of which is more efficient, both in terms of $/hash and Watts/hash.  My guess is those are pretty close as well.

Sorry dude, your the one asking for the information... not my job to do the searching for you.  The link, and the search function there, will get you close.

Update:  Was curious just how hard it would be.  Hit http://asic.usertalk.info as a guest, clicked the "Search" button, typed in "X13", and the 2nd hit was "What are all these algos".  That is the link you want. 

Many are described over on http://asic.usertalk.info...

9.1.0 used the standard 4/sec hashrate window and jumped around a lot.  Suggest 9.1.1 or 9.1.2 (latest) which uses a 30/sec hashrate window.  Not perfect, but a LOT better.

Cassey

Very cool.  Out of town for the weekend, but will player with cpuminer when I get back.  Can you share your startup string for cpuminer?
