I was able to solo-mine two consecutive blocks for Yacoin twice this morning, hehe. Once around 06:15, and once around 08:28 ...

Thanks Christian for your generosity. A forum lurker mostly. Just wanted to thank you for your work and effort. 1LTC in as requested, hope more will come your way (217fdc8b8d4071d04344eef7fea90a6150487a244783884009e8e5111121e7a2) Cheesy

also, usually I modify the autotune to limit the search space via something like (GRID_BLOCKS *WARPS_PER_BLOCK / LOOKUP_GAP < 50) continue; really speeds up the search by ignoring the really slow low warp counts, but not sure if I'm missing something?

Experience with the Y and Z kernels also indicate there's about a 10-15% gain on my cards.

I have been testing b114.
It is a little slower than cudaminer-2013-12-18 on a GTX760 (~drop from 225 to 215kh/s)
And a lot slower on a 780 Ti (Dropped from 550 to 450kh/s)
Both are x64 because x32 has been slower on my tests on the 760

Speaking of speed, I expected the 780 Ti to get closer to 800 kh/s based on what I saw listed in the google spreadsheet

Double check the block explorer - there are no two hour gaps between consecutive blocks in the last 12 hours.  What block numbers were they?

I think he meant finding consecutive blocks two times, as in two blocks around 6:15 and two blocks around 8:28

450khash/s is a bit low... I am able to achieve (but not this version) around 720khash (mod bios + oc which should give on stock around 600khash)

Nice work on the new Kernels. I'm able to squeeze 280 k/hash out my 660ti with stock clocks.
Edit: Kind of curious if implementing a backup pool feature is possible in the future?

PSA:

Based on current trading values at bter(Yac), coinedup(Vtc), and coinbase(Btc) here are the facts.

1 Yac = 2.56 cents
1 Vtc = 33.63 cents

Therefore 1 Vtc is worth 13.14 times 1 Yacoin.

Look at your coins per day of both. Are you making 13x more Yacoin than you could Vertcoin?

450khash/s is a bit low... I am able to achieve (but not this version) around 720khash (mod bios + oc which should give on stock around 600khash)
The 450 is only on the b114 unofficial build, on the latest official build I am averaging 550 (although I have seen it peak once at 600 I think).
It is actually a factory overclocked card, specifically a:
http://www.newegg.com/Product/Product.aspx?Item=N82E16814125489

Core clock: 1020 mhz
Boost clock: 1085 mhz
memory: 7000 mhz

Looking at the spreadsheet again, people are getting between 650 and 600 kh/s at my clock range, so it was my fault for not paying attention to the OC level.
The extra 50 kh/s is probably due to it rendering windows because its my main GPU and not a headless mining machine.

PS. I should like to point that my main point was that switching to the new b114 caused a significant hash reduction.
Luckily I was being pessimistic ahead of time and only ordered one card to test it out before committing to a large mining investment.

PPS. Something interesting happened, the GPU crashed (and so did firefox). After which cudaminer went from mining at 550 kh/s to 5500kh/s
or at least so it said. It didn't manage to submit any results. I will keep an eye on it

If you switch to a development build and are getting low Scrypt rates, try the Z or Y kernel instead.

Why is YAC suddenly deemed "dead"?

Everyone has an opinion Smiley  I'm actually buying hardware specifically for YAC at this time.  Beave162 and I have been tweaking and tuning for a few weeks now.  Returns have been good so far - the coin is slightly undervalued right now, so everyone is being advised to hold them Smiley


Difficulty is also dropping as some miners seem to be searching for alternatives. Meaning that you can expect more YAC per day with the same hardware.

Out of curiosity: what hardware did you select for optimal YAC mining? In my opinion, GTX 660Ti cards are pretty solid scrypt-jane miners at a good price/performance point.

My current setup are the R7 250's  with 2GB I've mentioned numerous times previously.  We've found that the R7 240's with 4GB actually outperform them by about 15% even with a lower clockrate and lower numbers of shaders.  This is attributed to the larger memory size allowing for a more aggressive workload.  I don't think we've even found their best performance settings yet as we're still trying various combinations.  ~2 accepted shares per minute per card for $100 vs ~1.7 for the 250's.

> CPR (Copperbars) is in N 13 (enters N14 on Febr 21);

does anyone know the correct Ntimestamp (startT) value for this coin? I would like to include it in cudaminer

The copy and paste methodology for creating crypto coins has led to confusion with the correct
startt parameter for miners.

For several cryptocoins (QQCoin, CacheCoin, Velocitycoin) I find these mining parameters with identical startT,
sometimes even in the official coin announcement threads. This is just sloppy work! Shouldn't this be the
timestamp of the genesis block?

Code:
–Nfmin 4 –Nfmax 30 –StartT 1387769316

EDIT: now I think I found what to look for. In src/main.cpp of every Yacoin clone there should be a line like

Code:
int64 nChainStartTime = 1367991200;

which is the number we're looking for. Can't get any more official than the timestamp embedded in the wallet client.

And considering the demise in YAC to BTC exchange rates... are there any other profitable scrypt-jane coins that we could mine? If some of you could share some firsthand experience that would be great...
Well not really:
ZcC is in N 13 but it's recovering from a fork for a while now so no exhchanges at the moment (enters N14 on Febr 17);
CPR (Copperbars) is in N 13 as well but I dropped it for some reason, not sure what I didn't like about it... (enters N14 on Febr 21);
APC (Applecoin) has potential, but it's only in N 11. Looking at one of the pools, the average hashrate per worker is around 294 kH/s. My GTX 660 gets 59 kH/s and ~30-40% CPU utilization (with -H 2).
Also, there's a bunch of coins between N 4 and N 7 but those are pretty much hit and miss. (cachecoin, microcoin, internetcoin, qqcoin, velocitycoin, freecoin, etc)
Basically, I'm silently waiting for the Keccak optimization so that I can test the !%+ out of low N coins because I'm starting to dislike YAC a lot and there's no way scrypt is more profitable with low-mid range cards like a GTX 660 (260 scrypt khashes vs 3.4 SJ N14 khashes).

Many thanks to bathrobehero for your information details. I was trying to find information of all scrypt-janes coins too but it is hard to find. And I still don't know how to get the information of the N-factor for each coin itself.

Btw, according to your question Christian and maybe you have interest too bathrobehero. I personally think scrypt-janes development is very important for the future of GPU mining, but right now scrypt mining even with cudaminer is very profitable depends on the coins you mine. In the last 5 days I was able to earn 2BTC with total 5.5Mhs with cudaminer scrypt. That means roughly 0.4BTC per days with merely 5.5Mhs. If you compare with multipool, middlecoin, switchercoin & co, or coinwarz, coinchoose you know what I mean. Smiley

cudaminer now includes Nfactor parameters for:

Yacoin [YAC]
YBCoin [YBC]
FreeCoin [FEC]
OneCoin [ONC]
QQCoin [QQC]
GoldPressedLatinum [GPL]
MicroCoin [MRC]
AppleCoin [APC]
Copperbars [CPR]
CacheCoin [CACH]
MicroCoin [MRC]
VelocityCoin [VEL]
InternetCoin [ITC]
RadioactiveCoin [RAD]

I might still add Pennies and Tickets (LotteryTickets) later. These also use scrypt-jane.

use like this:

--algorithm=scrypt-jane:AppleCoin  or  --algorithm=scrypt-jane:APC

VelocityCoin and QQCoin have the same start time 1387769316 apparently. One party fucked up. Wink

The fact that my scrypt-jane kernels use 4 threads per hash is actually the key for the decent performance of nVidia cards. It allows me to get 4 times the occupancy of the shader hardware, given the tight memory constraints. This... and the lookup_gap implementation I recently added.

In contrast, the currently fastest scrypt (non-jane) kernels run 1 thread per hash: There is no overhead for inter-thread communication and shader occupancy is not an issue considering the 128kb requirement per hash.

Because you are working on the AMD miner code, I think this information might be useful to you.
