Suprnova mined the first block of Pascal ..dancing like a queen :-D

And the next one:

[00:02:41] Found block for pasc.suprnova.cc!
[00:02:41] Accepted a4dedb2f Diff 397/8.222 BLOCK! GPU 1

Well CPU load is very high yes.. but for me it runs stable


If you help KlausT to fix the cpu verify issue in ccminer of his implementation then we have something to go...
Eventho lets combine our nvidia power to supernova lets beep these AMD morons where the sun never shines ;-D

This is what I get.

gtx 1070 (366MHASH)
3x gtx 970 (270-300 MHASH)

100% cpu load. Unusable.

ocminer is starting pool, also have some miner for windows and linux

we need ccminer, opencl is not good with nvidia, in fact my rig freezed and slowed down when i started it...

You forgot to multiply by the block size...

Yes but you have done something with the code.

//const uint32_t id = (headerIn[16] << 20) | (blockDim.x * blockIdx.x + threadIdx.x) * npt; (old code)
const uint32_t id = headerIn[16] + (blockDim.x * blockIdx.x + threadIdx.x) * npt; (your code)


In the old code (blockDim.x * blockIdx.x + threadIdx.x) * npt had to be less than 2^20.

If you increase npt, it will likely overflow the nonce range.

The original source had a limit on the nonce range of 2^20

With your block config. npt of 16 should be the maximum possible value.

8192*8*16=2^20

But not sure. I seem to get less solutions with npt=16 than npt=1

My version of Vorksholk/PascalCoin-CUDA, with fixes and speedups.

BTC donations:

https://github.com/pallas1/Pascalcoin-CUDA

Work in progress...

Thanks. 8% Faster than mine with 2 threads on the 1070.

I get 970 vs 900

I am running a test now and compare the klaus_t kernel with the same input data as yours.

edit: compiled with cuda52 instead of 61 I get 1050
edit: With npt=16 gives 1100

In last week I wasted 36h+ with 25G, so far no block and I am stubborn as hell

Me neither has a farm - just 2 Rigs with 12 Cards :-/
Even tho the output is 12GH/s i didn't make any block I think. Crap Nanopool and AMD.

Hi Pallas,

could you please include the proxy Jar to have the full package.
I assume its not working against a pool or like the pascalopencl miner where u enter an ip and port :-D

No pool, sorry.
And as I've said before, I can't test block generation (because my farm is too small), so it could be broken.

Pascal's diff is so high that even a flat 3x speed increase would not make it the best choice to mine.

According to cryptocompare, 3x speed would give you around $4 a card.

It's just not profitable to mine right now compared to other algos IF the pool and miners were all working properly. Pretty sure there is already work under way for private Pascal miners, if they don't already exist. Pascal has a a lot of available overhead. Each one of my rigs draws about half full TDP, so there is a lot of room there.

A lot of animosity surrounding this coin. Everyone is doom and gloom while we're waiting for devs to start ramping up the miners and iron things out. This still could be a very healthy market for Nvidia depending on where the cards end up after being optimized.
