You mean like this?

Matthew:out

May I be a contributor?  My username is Smeagol-Gollum on github.

Edit:  I submitted a couple of pull requests, you should see me now!



Merged.

Seriously, forum? I post three times in a row and it still doesn't accept the post  Angry

I have personally purchased a VPS to be used as a node. $4.05, paid in BTC. Over half the amount of BTC that I have mined.  Undecided

Matthew:out

Thank you!  Hopefully the coin will compensate you and get back your BTC! (open source devs never get paid, maybe this could be like DVC)

Well, it expires on September the 25th, so we'd better be quick.

VPS donation address (not owned by me, but by the VPS company): 16F3yJyqfEZFAFwct97qcB71Cxn2QwCMJu Every BTC0.03531258 is another month on the VPS.

As for coding, would it be good to create a github repo and have forum members submit pull requests?

it's the same, there is a binary posted about 3 pages back that someone was nice enough to make. If you feel adventures the source has been moved to github

I can upload a binary as well if there's interest.

That would be great, I would like to see it tested on something not AMD first. There is a "makeprofile.sh" script. It now has enough warnings that I worry it may have issues if not tested. Looks good right now, but the goal is fast, not necessarily good. Anyway, if the middle two lines match anything else the script prints out, at least two hashes where done correctly....


Oh, and there is a new option.
./configure CFLAGS="-msse2 -O3 -DCHEAT"
needs testing but the idea is that it's faster to just try a new nonce that run groestl twice. Anytime that section is found to be needed ran, it just give up. Half of the hashes end up being garbage. But, it now does more than twice the speed, for a net gain. EXPERIMENTAL, need to be ran to see if actually improves payouts as it may be losing shares. Still runs that section when required, but never twice.

Definitely experimental, considering [2013-08-28 16:48:36] accepted: 0/106 (0.00%), 0.00 khash/s (booooo). I'm switching back to v1.

Crypto++ is a b---- to use.

Can anyone recommend an alternative that has the algorithms MARS, RC6, Rijndael (AES), Serpent, Square and Twofish?

Quick update for everybody: I'm currently working on a small benchmark so you can see roughly how fast your machines will be when they start hashing parabola coins. It isn't much, but it's better than nothing.

Go for CPU only and ask for help as you will need it.

Thanks!  Matthew has proposed the new algos, will they be CPU only?

I cannot guarantee that. If scrypt, which is very memory intensive (GPUs are rubbish at that sort of thing), can be ported to the GPU, then it's most likely only a matter of time.

Also, I would like to make it sort of devcoins-like, where the developers get a certain percentage (like 1%), rather than premine, for extra services after launch.  (E.g. Is it possible for every 99th block to have double the amount of coins, but 1/2 goes to the devs for bounties and 1/2 goes to the miner)

I can try for you, but no guarantees. Heck, I've never really looked at the source code before...

Finally put my code up on github.

https://github.com/uncle-bob/quarkcoin-cpuminer

I'm looking for suggestions or ideas. Groestl-Hash seem to be the deal breaker right now. It's taking up as much time as all other 5 hashes combined. Any speed up for Groestl would be a win. Currently the V1 release confuses the compiler slightly less and is a smidgen faster. However I think this code is currently the best option for speeding up beyond that. It's still around twice as fast as the default miner.

Added bonus, almost everything for quark now fits a single function. While it won't fit on a GPU until the code size is reduced and memory is shrunk, it's just yet. Consider this my last update for cpuminer.

I wrote this cause I'm greedy, and so I leave my tipjar.
BTC: 1DaSUSqcr13G4QJYamsecW6yHh95QTT39R
QRK: QQRNpg7aGHcvgEFvXEk1DoCtLydboVsAzf

Is this faster than the other quarkcoin cpuminer?

By a long shot, yes. I get an 85% speedup from using it.

Something I've only just noticed: the Quarkcoin splash screen has a copyright year of 20,013.

Huh. I guess Quarkcoin really *is* the future.

As for AES-NI - don't forget that code won't run on processors that don't support it.

Matthew:out
well, almost any CPU thats worth it has AES-NI support, a simple check in the configure script can handle it while in the code its handled with #ifdef Smiley

So you've never heard of the Core 2 family then?

At least two people in this thread use Core 2 based Xeon chips. For £35 each, they are a bargain.

How about a bit more on the specs?

Semi-scarce, block reward will probably be a random amount between 2 and 6, but there will be a bonus "square" block.  (Parabolas). e.g. Instead of 2 you would get 4, instead of 6, 36, etc.

We will try to implement a primecoin-like proof of work scheme (hashing parabolas with complex solutions, etc), or it will just be a sha256 or scrypt coin.

If you have something to bring to the table just PM!
Go for a CPU coin, not sha or scrypt.
Also fix your english.

I have proposed to x2 that we use Twofish, Rijndael and Serpent in a Quark-like style (Quark seems to have used SHA-3 candidates) to at least be different.

from what i can see, cpu miner takes dual quad xeon l5420 from 290000 to 320000  so a reasonable improvement over the wallet but not a massive amount on ubuntu 64tbit

And the improved version posted a page or two ago takes it to 600 kH/s. I can vouch for that figure personally, being the proud owner of one of those machines.

Matthew:out

Hi,

Do you mean this one

https://github.com/Neisklar/quarkcoin-cpuminer

built with this
CFLAGS="-O3 -Wall -msse2" ./configure ?

i'm seeing 41000 per core? so x 8 about 320 000kh?

Dual quad l5420 ?  are you sure you are getting 600 000?

that's the one i am using?
also is your machine windows 64 bit or ubuntu?

I have made you a build of the CPUMiner source that does 600 kH/s on 64bit Ubuntu on a dual L5420 system.

http://thelumpit.net/cpuminer.tar.xz

I haven't tried V2 yet, but I will do. V2 offers a very small improvement to each thread, but considering there are 8 threads, it isn't too bad (600 kH/s to 625 kH/s). New build here.

237  Bitcoin / Mining / Re: p2pool deposits to cryptsy - why not? on: August 22, 2013, 08:22:05 PM
The fact that generated transactions come from thin air. Cryptsy's software doesn't accept transactions that come from the address 0. So you have to move them manually.

I didn't realize this. I thought a transaction was a record consisting of at least:

A) A recipient
B) A sender
C) An amount

The key for this record is the transaction ID.

Which part of this do you say is "0"? If you mean the sender is 0, how is this possible? And if so can't I just create a transaction that sends 10000 BTC to me from sender 0, and get 10000 BTC for free?

Or do you mean the Tx id is 0, and if so why would a pool be generating transactions with a zero txid if this is causing problems with exchanges?

I'm sure there's something I am missing here :-)

-Michael


The sender.  You can't create a transaction like that because 0 is not a valid address in any kind of coin. The fact that it comes from an invalid address confuses the software.

Grue is right, though, this is just speculation.

Whatever the reason is, don't try it. Warnings are usually there for good reasons.

239  Bitcoin / Mining / Re: p2pool deposits to cryptsy - why not? on: August 22, 2013, 09:09:00 AM
probably because the transaction shows as "generated" rather than a normal transaction.

When is a transaction not "generated"? All transactions are generated somehow.

And what is the problem with generated transactions that make them impossible to process? If someone was mining directly to my private wallet, it wouldn't be a problem would it?
