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:

how to fix it?
thx

ps
i was tried nothing changed code for equihash 200_9 is ok

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. Cheesy

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?

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

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

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...

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

My fiber network (+4G phones too) is down since 6h in the local area (at least 30km around). Never happened so long and still waiting explanations...

Maybe some meteo issue, we had lot of snow today, and storms and lot of snow/rain the last days... but nothing sure

Official Ccminer v2.3.1 by Tpruvot

https://github.com/tpruvot/ccminer/releases/download/2.3.1-tpruvot/ccminer-2.3.1-cuda10.7z

Jan. 30th 2019 v2.3.1

Handle Lyra2v3 algo
Handle sha256q algo
Handle exosis algo
Handle blake2b standard algo
Built with CUDA 10 for SM3+ devices, SM 7.5 arch was integrated, but seems to only waste disk space.

Note: CUDA 10 requires a nvidia driver 410.48 or more recent.

Good morning,

My name is Jeremy and I am one of three co-founders of Vidulum. We are testing a different variant of the Equihash parameters for our project. Would you be possibly be willing to add it to your mining software? We have successfully been able to get the params to work with our daemon/CPU mining on testnet, but we were unable to compile a GPU miner. Any input at all would be very much appreciated!

Feel free to contact me here, or;
[email protected]

Sincerely,
Jeremy Dixon

The market crashed and all the ccminer devs are making fee-miners or private miners...

I just released my 2x verus miner as opensource :-)
