[ANN] ccminer 2.3 - opensource - GPL (tpruvot)

[scryptr]

I'LL LOOK FOR A NEWS REPORT--

Sorry to hear about it.  If it is that severe, it may be in the news.  Glad to see the new release of CCminer, however.

Hope things return to normal!        --scryptr

EDIT: Apparently, there is severe flooding in Northwest France, and snow in the Alps with the possibility of avalanches.       --scryptr

[Epsylon3]

Wallets are still connected via the backup connection, so payouts were made normally.

But this connection is not very good today and i cant resume normal operations...

[scryptr]

YIIMP IS UP--

I connected to Yiimp today.  My shares are where I left them, and the site looks as before.  Hope things recover smoothly!       --scryptr

[Epsylon3]

this issue affected 12500 users and 200 companies around... for 24h + mobile phones too (at a smaller scale)

[tbearhere]

That's a big outage.

    }
    return sz;

I tried to create an executable for windows but this error appears "135 error c2668: 'sqrt': ambiguous call to overloaded function" Can you tell me why?

That's because sqrt() only uses floating point variables (float, double, or long double).
Adding casts to double should fix the error:

Code:

for(uint64_t i = 3; i < sqrt((double)number); i += 2) {

Code:

uint64_t sz = NIGHTCAP_CACHE_BYTES_INIT + (NIGHTCAP_CACHE_BYTES_GROWTH * round(sqrt((double)(6 * (block_number / NIGHTCAP_EPOCH_LENGTH)))));

Code:

uint64_t sz = NIGHTCAP_DATASET_BYTES_INIT + (NIGHTCAP_DATASET_BYTES_GROWTH * round(sqrt((double)(6 * (block_number / NIGHTCAP_EPOCH_LENGTH)))));

ok, thanks.

how to change those code for support equihash 96_5

i was tried changed the  equihash.h :

Code:

#define WK 9 to 5
#define WN 200 to 96

released ccminer.exe  but test mining coin  got this error:

Code:

Thanks for the input Ilya, official ccminer is available for download at http://ccminer.org/

And don’t forget that it was, is and will be opensource, thanks to Epsylon3 and other contributors.

This is what I get when running ccminer, it recognizes my gpu and even gives a hashrate, however it also says there is no kernel image available for execution on the device. Should I be concerned? I've read posts elsewhere about similar issues, but none of these were detecting the gpu. The other posts mentioned setting the cuda architecture to the proper one, but I cannot seem to grasp how that is done. I'm running Ubuntu 18.04 and cuda 9.1 with a GeForce GT520.

i just wondered if anyone seen this issue or possible bug. Ok so i set up 3 wallets to do a time limited rotate of the wallets and i set time up with a max dif.  Maybe i am doing
something wrong i have tried in both windows and in linux.

here is my attempt with just max diff

:loop
ccminer-x64.exe -a skein -o http://192.168.1.215:9333 -u htc -p x -d 0 --cpu-priority=4 --max-dif=5.0
ccminer-x64.exe -a qubit -o http://192.168.1.215:14242 -u htc -p x -d 0 --cpu-priority=4 --max-dif=25.0
ccminer-x64.exe -a myr-gr -o http://192.1681.215:9335 -u htc -p x -d 0 --cpu-priority=4 --max-dif=5.0
GOTO loop
pause

it wont move off the first one at all and thinking i would mix in time limit to see if it would wait 180 seconds and go to the next one every 3 min

:loop
ccminer-x64.exe -a skein -o http://192.168.1.215:9333 -u htc -p x -d 0 --cpu-priority=4 --max-dif=5.0 --time-limit=180
ccminer-x64.exe -a qubit -o http://192.168.1.215:14242 -u htc -p x -d 0 --cpu-priority=4 --max-dif=25.0 --time-limit=180
ccminer-x64.exe -a myr-gr -o http://192.1681.215:9335 -u htc -p x -d 0 --cpu-priority=4 --max-dif=5.0 --time-limit=180
GOTO loop
pause

it wont move cause the miner didnt mine 3 minutes is what i am seeing.
If i runn with the --time-limit=180 command behind each one only it rotates thru them then goes back to the top one no issue.

Time-limit is the only one that exits, the others like max-diff, max-temp just wait at idle.

this is perfect and thats what i am looking for. A few months ago i was using the time-limit command and found
my gpus stuck on one wallet or pool for hours because the pool went down and i didnt figure out why it didnt move
on after 300 seconds until now because the time-limit has to mine that pool for 300 seconds or it wont switch.

you can easily recreate the issue by putting in a bad address or password in the first one and try yourself. it wont
go to the next wallet or pool til it mines that pool x seconds.

Hi. Will you add the SINOVATE in your pool and algo X25X.
Thanks.

Hi, i have the following error mining on AWS EC2 instances, perhaps you have any advice for me?

Sorry for off topic but I think many here have mined Boolberry BBR. I thought you may like to know BBR to Zano swap. And yes BBR will still be supported after the swap ends July 30th 2019.

When Mining Phi2 there's a "bug" in the software.

the use_roots flag for LUX and GEX is now being triggered and activated whenever a job contains a root parameter.
However the flag will never go back to false after this.

When using profit switching this causes a serious problem.

Please move the initial ' int use_roots = 0; '
To inside the ' work_decode ' function, so it gets checked on new jobs, to provide compatibility with profit switching.
