[ANN] [QRK] Quark | Core 0.10 upgrade

[K1773R]

about how many blocks can i expect per day at 160k Hashes per sec?

Maybe once every couple days...

thats crazy bad profitability :/

At time of writing, the Quarkcoin difficulty is 441.12747160.

The formula for seconds per block is 2^24*<difficulty>/<mining rate in hashes per sec>

2^24 * 441.12747160 / 160000 = ~46,256 seconds per block
46,256 / 60 = ~771 minutes per block
771 / 60 = ~13 hours per block.

There's the maths for you.

FWIW, here's what it would take me, mining at roughly 605kH/s:

2^24 * 441.12747160 / 605000 = ~12,233 seconds per block
12,333 / 60 = ~206 minutes per block
206 / 60 = ~3 hours per block.

That's a 4.3x decrease in time, for a 3.8x increase in power. There are small economies of scale.

Thx for the calculation but what about the orphan rate ?

Most of block found are orphan, how do you determine the % orphan rate ?

most are orphan? almost none of mine has been orphan! FUD!

@quarkcoin @Guido

That looks amazing!

I'm holding some qrk...usd worth is similar, that's true.
I expect block reward halving to increase price over time.

post your quarkcoin.conf then

If you got many orphans that's probably because you solo mined with the cpu miner but used the standard scantime, which is 30 seconds. I recommend adding -s 1 -q 0 -E 2 to the commandline when solomining with the cpuminer.

[Kryon]

want to collect some statistics

so

quark-v2_w64
AMD Athlon X4 750K(4 cores) minerd64_sse4.exe - 380khash

[eule]

Sure:
minerd_qv22_sse4, Core 2 Duo E6400 @ 2.7GHz: ~190kH/s

Hem sorry, what is -q and -E ? it's not listed in help and doesn't seems to work

Queue and expiry-time, thought the cpuminer had those options too but not sure, I remember these settings from countless scrypt orphan orgies. Most important to avoid orphans is the -s aka --scantime setting though (the amount of time between checking for new blocks).

That's great, many thanks.

The current difficulty is just way too high!

[eule]

The current difficulty is just way too high!

Stop mining and it will drop a bit.

Well if i turn off my botnet you can expect at least a 1/5 drop

Aren't you complaining about difficulty everytime, Lauda?
Stopped mining after a day. Sold them(16'000) for 0.21 BTC

I think that I am, but I'm causing it  
I sold ~20k for 0.30 or 0.40 not sure.  
That is, at the day of release.

i knew i should have kept my mouth shut in cryptsy chat about that lol

Repost. Updated

AMD Bulldozer optimized client Win64bit and maybe some intels
---===---===---===---
built from StoneFoz version1 Which doubled speed and beyond

v2 was having many issues (+reject, +orphan for me) , bin below is version 1

8150 Stock 8 cores = .8~1.1 mhash
8350 Stock 8 cores = 1~?? mhash
4300 Stock 4 cores = .46+ mhash=+

Bulldozer 1 (more compatable) and Bulldozer gen 2 (more specialized)
https://sourceforge.net/projects/philosopherstone/files/QRK/

Tips appreciated: QRK: QQVzchEu7aqAfc71NZa1TYi3toih6abCtk


Re-posting because this is not AMD bulldozer only, and may in fact work on the newer intels as well.

this is not the uber optimized client, will post when over 2mhash per chip

and i'm telling you AGAIN it crashes on my Intel CPU (both versions in the archive)
i downloaded it before and tried them all and i re-downloaded just now and tried them all..
arguing doesn't make code run lol

Intel Core 2 Duo E7500 = fail / crash on start up - win 7 x64
and yeah i checked and these are 64bit builds not x86

and your welcome for the constructive feedback and time and effort i took to test this everyone

edit:
I'd love to know how that guy is compiling code from GitHub.. all its giving me is compiler errors with mingw on windows
i can get various previous version of the code to run just fine..
i often see "get the tarball" but how am i suppose to find that ?
all i can see on the github page is the button that says download zip or that other page with the .zip + targz
and that can't be the tarball because i see these devs constantly telling people asking for help compiling it code to not use it and use the tarball
when autogen.sh fails etc.. so obviously the tarball should have more files inside the archive in it so you don't have to run that command right ?
this quark miner stuff is severe pain in the ass for a noob to come along and get the newest version and compile.
these miners should have dedicated topic or do they already ?

bottom line: I'm figuring it all out on my own anyway, so whatever keep scrolling guys lol
started in on linux and c/c++ well over a decade ago and its sucks balls i can't use VS as an ide
so yes i am a noob but no i am not.. i may start a new thread soon with a tutorial on building this on windows for people..

Just mined my first block of 512
