NSGminer v0.9.4: The Fastest NeoScrypt GPU Miner

[krisdavison]

Only three days until the switch for phoenixcoin. Hope your all ready?

It may take a couple more days to reach block #400K due to coin switching pools. They try to instamine without much success and leave, but the network generates less than target 960 blocks per day.

Phoenixcoin has gone Neoscrypt, so no ASICs can mine it and as there is yet to be made a GPUminer, no GPUs either, so at the moment you can solo mine with your CPUs.

Time to go oldschool and do some CPU mining, looking forward to the GPUminer being made.

Happy pxc mining!

[asdlolciterquit]

what kind of speeds can be expected from GPU's?

yep, can we have some stats?

[BitcoinNational]

Phoenix ... now in retrospect ... the name seems so well conceived.  Was it foresight?

To soar up with but a feather, as the scrypt empire burns down to the ground of asics, there ghostlander greets you.

GPU miner has not been finished yet, so there is no stats for it yet.
So at the moment Neoscrypt can only be CPU mined, but that will hopefully change soon.
But in the mean time let your CPUs make some money.

Well, good luck, then. Nice job making a new algo.

[Conqueror]

Coinwarz just added Neoscrypt 

[robyone]

at least one miner is GPU mining as of 1 hour ago, total hash increasing with ~800KH/s increments which suggests GPU.
but no GPU miner software is yet public.

Nope, there are people with large CPU farms like his one delivering 450KH/s. There are also botnets.

Any pool to mine PXC? bcoz I see all p2p either dead or outdated
MinePool - no neoscrypt support
Multipool - Abondoning PXC

so any pool left to mine?

I have a lot of trouble understanding.
Claimed to be harder on memory, takes 20 rounds of salsa (already too much to be memory-bound) adding other 20 rounds of chacha?
Half the memory amount, paper claims to be "1.25 times more memory intensive"... due to cache effects I assume?
Anyway, scrypt was compute bound... I've been looking at this for a few days and I cannot understand what's the whole point.

What's your question?

[MaxDZ8]

Considering the massive amount of computation, what does "memory intensive" mean?

Memory read/write operations. Why don't you look at the source code?

[MaxDZ8]

Why don't you look at the documentation on GPU programming?
Original scrypt was already compute bound. Neoscrypt is even more compute bound. People in GPU programming would go great lengths to have half the arithmetic intensity original scrypt had.

I'll ask you again: what does "memory intensive" mean? Fetching some memory every once in a while isn't an "intensive" operation.

My Cuckoo Cycle PoW spends 67% of its time on memory access. In other words, if you leave out all memory accesses, and just do the remaining computations, then runtime reduces to 33% of original.

That's what I would call "memory intensive".

You can do the same test for NeoScypt. Run it with all memory accesses removed, and see how much runtime is reduced.

Getting following error when trying to run the miner on PiMP:

Segmentation fault

Thoughts?
