is this coin in any exchange?

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

scrypt(N, 1, 1) support was added on may 25, i can't tell if there is a windows build somewhere, but there are building instructions on github.

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...
sorry, can't help you there as i'm windows free since year 2000, but you can gently ask cbuchner1 on this thread for an updated windows build...

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.

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.

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).

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.

There's no gpu mining (yet and probably long time) and based on my personal experience we won't see 92 billion coins until about 300 years. Just mine with the wallet as it states in the OP and come back in a week you may have 40-150 coins. This is high coin count with mega slow distribution. In other words no miner dumps and cpu only.

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.

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...

Oh well, at least it keeps it going at a nice, slow... but steady pace. ;-)

Here it the N expression:
https://github.com/IMAcredit/imacredit/blob/master/src/scrypt.cpp#L261

So nfactor is 16 -> n = 1 << (16 + 1) = 2 ^ 17 = 131072

Other values are not good.
