[ANN] cudaMiner & ccMiner CUDA based mining applications [Windows/Linux/MacOSX]

[cbuchner1]

try the new commit. Got to create a new worker lol

[bigjme]

compiling and ready with a new worker lmao

EDIT
got to 24/26 then got 4 repeated shares

[bathrobehero]

hashfaster:

3] accepted: 180/182 (98.90%), 1003 khash/s (yay!!!)

Though, this one usually goes well at the beginning....

[AizenSou]

i just started pool mining. and yep the same 4 people. will be me, you, bathrobe, and christian until the next big hit haha

31/47 shares on max.netcodepool.org

ouch!

EDIT

almost at 50% rejected now, this is aweful lmao

max.netcodepool.org is bad for cudaminer.

Try https://max.hashfaster.com or pool.chunky.ms/max.

These two have better accepted rates for me.

right now its more to completely remove the number or rejected shares if possible

thats what we are trying to remove now :-)

[shadypepe]

guys so funny pump and dump to the MAX happening right now on mxcnow https://mcxnow.com/

[AizenSou]

Christian I got my first 1mil MRC after 3 hours of mining. It is somehow too fast or I'm just too lucky today

[cbuchner1]

Mining with a single GTX 780 on a worker I can much better replicate the problem now.
I get huge reject rates too.

A string of boo's is always interrupted by a "stratum detected new block" message.
But somewhere while working on that block the nonce space overflows and we're
finding previous results again.

Meaning that a lot of the work is wasted.

welcome to the millionaire's club! Here, have a cigar.

[bigjme]

christian something has gone wrong
i am hashing all over the place now, as low as 1Mhash/s

at 45/64

every failure is a duplicate

EDIT: i just saw as low as 500khash/s being done
and that gets me the share accepted! lol

99% gpu load the entire time
and now down to 54/85

EDIT 2

so bad i have had to close the miner

Restart your PC and see if it gives you the same problem. I had this issue with the 12-18 version, seems my drivers had somehow stopped giving a damn. Rebooting reset it.

[Stanr010]

Vertcoin is currently very profitable.

Moreso than Maxcoin?

+1

Now that the problem has been identified, I've got faith in you that it'll be fixed in now time

I have also the same problem the hasrate is all over the place and rather low

Is it just me or did smalltimeminer's max pool just shut down and take all my coins with it?

[solvent]

I got an error in last build attempt.

Code:

maxcoin.cpp: In function ‘int scanhash_keccak(int, uint32_t*, const uint32_t*, uint32_t, timeval*, timeval*, long unsigned int*)’:
maxcoin.cpp:90:42: error: ‘min’ was not declared in this scope
   pdata[19] = min(max_nonce, n-throughput); // CB: don't report values bigger max_nonce

[sidhujag]

okay, this looks like it might overflow very quickly

Code:

        uint32_t end_nonce = 0xffffffffU / opt_n_threads * (thr_id + 1) - 0x20;

assume only 1 thread mining, then end_nonce will be 0xffffffdfU

now the issue is that when we compute in chunks of about 30000 hashes at once
we will overflow work.data[19] so that the following condition is never met!

Code:

        if (work.data[19] >= end_nonce)
              stratum_gen_work(&stratum, &g_work);

TODO: replace the 0x20 with a value large enough so that overflow will
          not occur.  Alternatively make sure we never update work.data[19]
          with a value smaller than the previous value. Instead write 0xffffffffU.

Cant you put it in a long or bigint?

Pff.2 very crazy days and nights. I came here after christians post on the nvidia cuda forum. I went through 100 pages until finally managed to compile cudaminer and the wallet, just to find that it is too late. Anyway I tried the latest version and I get the same error as in the quote. The previous version I have is from 7th  I think.


This maxcoin is madness, I am doing some solo mining and some in the pools. In both cases I have no ideea if the work is accepted all, or just 10 %. The solo miner reports no errors, just new work. The pool minin at https://max.mining4all.eu gives lot so Yys and ver few Boos, ut I have no ideea if it works or not. So far very small returns 0.3 maxcoinf for 6 hours. The VTC seems more profitable as I seen so far.

Is it just me or did smalltimeminer's max pool just shut down and take all my coins with it?

I hope not. I did not much left there. I set all my pools to auto send to wallet in case they do shut down for some reason. It was a good pool for me.
