Is this real? 8 hours mining YAC

[Xanthe]

FWIW, I own my server farm (as made rather public on the first day or two of the coin launch), and definitely pay my own electricity.  And despite being one of the few that did implement GPU mining of YAC (just not necessarily one that performs as spectacularly as people seem to think every GPU implementation is going to achieve), I still CPU-mine YAC at this point.  Tons and tons of cheap Xeon-based IBM BladeCenter blade servers that people dump on eBay for pocket change just because they're a couple years old and not the latest-and-greatest blade servers on the market, reasonable power costs, and sensible and efficient design of data center cooling are key here.  Per unit of CPU performance, I pay less than half what someone would pay merely for a motherboard, a bit of RAM and an i7-2600k, to achieve the same level of performance, and end up with carrier-class hot-swappable hardware, with more redundancy than you can shake a stick at, that just doesn't fail except under unusual circumstances.  This was formerly IBM's hardware platform for building supercomputer clusters for NSA, who tend not to have a sense of humor about power supplies that fail when you look at them funny.  This just comes down to resourcefulness and ability to scrounge the right hardware (or even to know what to look for in the first place) to keep costs down.

You can bet I would've really cleaned up had I seen the delayed YAC announcement sooner than 8 hours after the coin finally launched..  I even had the entire server cluster all prepared to network-boot a YAC-specific Debian Linux image off one of my file servers, and it was all tested and ready to go prior to the originally scheduled YAC launch date/time, I just needed the final version of the client.  But alas, I was asleep (and/or in the wrong part of the world) at the time the coin finally launched.

Hi WindMaster!

I've read a lot of your posts around these forums regarding YAC as I've followed its developments quite closely. I inserted the caveat in my above statement specifically thinking of people like you. I have no qualms with the way you're mining and in fact I think it's great. As you explained... you've been resourceful and smart in the way that you've gathered your equipment and I really respect that. I understand that you own and pay for all of your equipment (and apparently can still profit from YAC mining) so I'm not trying to disparage you in stating that a large percentage of the YAC network hash rate is in server farms. I just think it's the truth (again, I don't have proof, it's my opinion). And I'm not saying there's anything right or wrong with server farms ruling the network, just that they probably do. ;P

As for GPU mining, I don't think either of us can really be sure what's happening on that front. You state that you are among the few who managed to implement GPU mining but can you really be sure of this? I think no one can. In situations such as this where there is money on the line, a lot of smart minds (like yours) go to work. I would hazard a guess that most people capable of creating a YAC GPU miner are not the kind who would be quick to telegraph such things to the world.

It sounds like you were indeed prepared for the YAC launch -- it's too bad it didn't go off as the developer had stated (there was even one false launch!). I'm sorry to hear that you missed it.

Do you have some Ebay link of that specific hardware you use

Without endorsing any particular eBay vendor, and just as an example of almost identical HS21 blade servers to what I use (most of mine have E5450 CPU's rather than E5440's, but that's only a few % difference in performance):

http://www.ebay.com/itm/10-PACK-8853-AC1-IBM-HS21-BLADE-2-x-E5440-2-83-GHZ-QUAD-CORE-8GB-RAM-2x-73GB-/200876881184?pt=LH_DefaultDomain_0&hash=item2ec531f520

Remember, that price is for a pack of *10* blade servers, not just one.    8GB ECC RAM and dual 73GB SAS hard drives included even (though I prefer just network-booting any slave workers in my cluster).

Then for each group of 14 blade servers, you need a BladeCenter chassis, management module (AMM if you can find one), Ethernet switch module, and depending how many power supplies came with your chassis, a couple power supplies.  All of the above are dirt-cheap on eBay too, even the old original BladeCenter E chassis that work perfectly fine for everything right up to the newest blade servers from IBM (albeit with some specific requirements for slot ordering when combining newer HS23 blades with certain power supply types in old E series chassis).

In addition to that, you do also need a decent IT skillset.  It's not at all a difficult platform to work with, but would probably be pretty intimidating to someone with no network engineering or data center experience.  You manage all the servers through video and keyboard redirection to a web browser interface (via a Java version of VLC), and a shared DVD tray / USB slot that you can connect to any of the 14 blades in a chassis at a time.  You can even mount a CD/DVD drive or ISO image from whatever computer you're hitting the management module with your web browser from, and it appears to be an actual hardware CD/DVD drive attached to that server.  Makes OS installation a breeze, you never have to get up from your desk to go swap install media.

Don't try to set up a BladeCenter farm in your home though.  The (dual redundant) cooling blowers are loud enough to wake the dead.  And you do need 208V-230V power as well (might be a problem for some people, not for others).  And don't expect to get rich mining YAC either.  I *do* have relatively inexpensive power.  I mine with them because I have them already for another business doing render farm jobs on film projects, and there are times they're free to do other tasks.  If it costs less in power to leave them up and mining YAC, great.  Otherwise I'd power them down when no render farm jobs are queued up.

And for those with an eye toward power costs, you can measure and graph the power consumption of every individual blade server and other component installed in the chassis via the management module's web interface.


Okay, this photo is actually one of my HS21 XM blades rather than a straight HS21 blade, but close enough, just trades some extra DIMM slots in place of the 2nd hard drive slot:

Thanks mate, too tired to read this carefully but will definitely study it when I wake up. WOuld love some of these toys, though I'm not in USA it might be too expensive to import it.

Try mine to P2P pool, with 300K Hash/s you should have around 100-150 YAC per day.

[ANN] YAC P2P Pool http://yacpool.cloudapp.net:8336 (fast, reliable, 1% fee)
https://bitcointalk.org/index.php?topic=223827.0

[bitdwarf]

So I made 15 cents in 8 hours or 45 cents a day.

With 5 computers.

Buy what you want to hold, secure it with mining.

I trade for YACs what I mine with my gnarly 6850 and CPU mine sometimes in a pool mostly for the sake of it.

[bitcoiners]

When the N value goes up the amount of hash goes down by ~ 50%. That's why people aren't seeing the hash rate they WERE mining with a few weeks ago.

In my opinion the N value went up way too fast too soon. We should be a year from now or so at todays N value (1024).

On the bright side not many coins are being made now which should make the price go higher.

Except you are forgetting one thing.  Nobody wants the fucking things.

[procrypto]

It doesn't make sense mining this.

I listened to myself with this kind of reasoning 2-3 years ago when I could've been mining BTC unprofitably, and look at where that got me. Sometimes you need to look further than your next payday.

Nobody wants the fucking things.

Well someone appears to, or we'd already have traded all the way down to zero. QED.

I remember your comments about this in the Yacoin thread. I pointed a few blades at it myself within hours of launch. I believe the problem was exactly the AWS system - way too much hashing power pointed at the coin which left thousand of orphans for everyone else. I did alright, but not as well as you as I recall made over 100k in coins, and then I stopped on day three and ignored the coin like so many others. Now, it's almost as worthless as all the other alts. For these coins to be viable - they need interest (hence why you see all the giveaways). Anytime a new crypto currency is created, early AWS/botnet miners try and sell it immediately at 5 ltc per 1k of x-coin. No buyers, now, they were burned.

[WindMaster]

Alternatively, get something like www.ebay.com/itm/Dell-CS24-SC-Server-2x-Intel-L5420-Quad-Core-Xeon-2-5GHz-16GB-4x146GB-1U-Server/121115794427

Well, 2.5x higher cost per comparable amount of processing power (L5420's are 2.5GHz, E5440's are 2.83GHz, E5450's are 3GHz), no redundant power supplies or redundant cooling, no remote management, and no hot swapping the servers (in a matter of seconds).  But other than those, or if someone just wants a couple dual Xeon-based servers..  At that kind of price, and factoring in higher power costs for the older Core2-based 5400 series Xeon CPU's, I'd almost just go for an i7 family desktop CPU + motherboard instead.  At least for YAC mining.  In terms of hardware quality alone though, the Dell CS24's are still quite a bit above desktop gear, just not as good on the price/performance curve.

Well, they are stupid and deserve to be burned if they act like this.

I never understood why someone would mine a new coin if they don't belive in it. Mining your 100k probably wasn't a problem for you, but buying so many is usually impossible witout paying far more than they were worth at that moment. There is no way to get so many new altcoins witout spending more than they are worth.

Agreed.  The N value is ridiculous at this time point, the coin is still a baby.

Keep in mind that as N goes up, the amount of decrease everyone gets is equal. For example:

Let's say N = 1
Person with 50 hash/s earns 50 coins a day
Person with 25 hash/s earns 25 coins a day
Their ratio is 50:25 or 2:1

Now N jumps to 2
Person with 50 hash/s is now at 25 hash/s and earns 25 coins a day
Person with 25 hash/s is now at 12.5 hash/s and earns 12.5 coins a day
Their ratio is 25:12.5 or 2:1

In other words, after 500 days and N is now 500 and they are getting 0.00001 hash/s, the ratio will still be 2:1. Meaning that it's still really the same.

This is why I believe the N value increasing isn't an issue. Unless someone can shed light on where the mathematics would be wrong? The way I see it, if I earn half what you do, it doesn't matter if I earned 1 coin or 1 million coins; either way I still have half the value of you.

Yes but what he was saying it's too soon for the nvalue increase as everyone should still be getting high hash rates and more coins at this point in time.  It's too soon for such little coin when the value of the coin is still really low, it's going to deter some people, as the OP is an example.

Okay

I got 5 YAC. The price for each YAC is .0003. Yap, there are 3 zeros there. That means it's 3/10000

If one BTC is around $100, one YAC is 3 cents.

So I made 15 cents in 8 hours or 45 cents a day.

With 5 computers.

Why would anyone mine this thing?

Even if the price go up it makes more sense to just put $1k, dump them, and then wait till price go up.

It doesn't make sense mining this.

we don't know we are not mining it

[WindMaster]

What higher power cost? That server comes with 400W PSU and as far as I know "i7 family desktop CPU + motherboard" systems usually come
with similar PSU.

The size of the PSU does not determine how much power the CPU(s) consume.  The TDP of two L5420's is higher than, say, an i7-2600k, while the i7-2600k is faster than two L5420's for most workloads while burning less power.

It is complete computer, just plug monitor, mouse, keyboard and network, and install OS. Much less trouble than IBM Blades + case + PSU, etc.

This is probably true if you're only looking for just one server.  I'd say the crossover point in amount of trouble is reached by the time you're looking at 2 or more Dell CS24 servers.  The price crossover point is definitely reached by the time you look at 2 CS24's.  Actually very nearly by the time you look at just a single CS24, depending how far you have to ship the BladeCenter chassis.

But by all means, no one else should look at the BladeCenter platform at all.  I'll continue being perfectly happy paying 2.5x to 3x less than the cost of alternatives for a given amount of processing power while never having to lug around a monitor, keyboard and mouse to connect to individual servers.  It'll just have to be my little secret how I keep hardware and operating costs so low on massive server farms.

When I mined, I got low acceptance rate. What's wrong?

[noel]

They infect their employers networks and use 100s of computets and free electric and make money.

mmmm anyone with hundreds of computers need staff

Hmm, it would be morally wrong to steal from your employer, but what about a unpaid traineeship where the employer doesn't mind if you run some hardcore mining. I don't know if this kind of tax evation is legal (probably not), but it seems impossible to prove and benefits both.

Assuming that you life in a state that spends billions on banksters or MWD I see no moral problem there.

[Oldminer]

The only person still mining YAC is Vladimir Putin

[smilez]

I'm mining yak's and making some nice profit. Too bad it went down today...

Still 2x the profit of ltc though.

[Swimmer63]

I have two GPU rigs, but am new to CPU mining.  For fun I started mining YAC on my work desktop via a pool.
I have an AMD FX-6120 Six-Core at 3.5 Ghz and 10 GB of memory.
I mined for about 12 hours and got 3 coins.
What am I doing wrong?  Below is my .bat

minerd-avx.exe -a scrypt-jane -o  http://pool.yacointalk.com:8336 -u Y51uiyQsGXGnVxxxxxxxxxxxxxxxxx -p x -t 20

[digger]

use this pool
