[ANN] Sia GPU Miner

[Taek]

Sia (www.siacoin.com) is a new decentralized storage platform, we're launching on June 7th. We've just completed a gpu miner for Sia. The gpu miner is incompatible with the download available at the website, so if you want to try out the gpu miner during beta, you'll have to build both Sia and the gpu miner yourself.

Sia repository here: https://github.com/NebulousLabs/Sia
GPU Miner here: https://github.com/NebulousLabs/Sia-GPU-Miner

Sia's POW algorithm is blake2b. As far as I'm aware, we have the only open source GPU blake2b implementation.

in the Sia repository, run 'make release'. Then run siad. The GPU needs to talk to siad while it is mining. To make the gpu miner, run 'make'. During the first few minutes, the GPU miner will be optimizing the number of cores in use. It should display a hashrate.

This is our first time making a GPU miner, let us know what you think. The currency launches on June 7th, we'd be excited to have you on board.

This makes it look like you don't have libCurl, which is how the miner talks to the daemon.

How to use Sia-GPU-Miner-master ?

NO exe ?

[djm34]

will it work with standard sgminer/ccminer (and getwork/stratum stuff) or is it something entirely different ?

It's entirely different. You can find binaries here: https://github.com/NebulousLabs/Sia-GPU-Miner/releases

Its working now to me either , but the rig shows activity only on one of the cards. Speed is about 32MH/s

Still can't start this new miner release "as is", Sia_GPU-Miner-v1.0.1-win64. Why does it seems that Wolf0 is smarter than developers of this miner?..

Because Wolf0 has been doing gpu mining for a long time, and knows his way around miners much better than we do. When it comes to mining, Wolf0 definitely knows more than we do.

On that note, the master branch of the official Sia miner has some recent changes + optimizations, some of which were made by Wolf0 himself: https://github.com/NebulousLabs/Sia-GPU-Miner

With the last version you can specify -p1 : the opencl platform is usually 0 but in my case it was 1 : I had the same error than you, and now it works.

Right, well, you need to find it, then. If you can build SGMiner, then you will be able to build this.

You'll need to find it, though. First, if OpenCL headers aren't installed, you'll need 'em. They're only needed for building OpenCL - not running it - so you may not have it already. Install them, do a "find /usr -name cl.h", and add that to the include path in the CFLAGS var in the makefile. If you have another problem after this at the link step, it's just another find command away, then add that to the LFLAGS variable in the makefile to make the linker search there.

Install them, do a "find /usr -name cl.h", and add that to the include path in the CFLAGS var in the makefile. If you have another problem after this at the link step, it's just another find command away, then add that to the LFLAGS variable in the makefile to make the linker search there.

all good ...

Good to hear; can be a minor pain without configure around to find stuff automatically.

exactly ...

if ./configure was there and active - it may have made the whole process a lot easier ...

eitherway - its a learning experience ...

i will be working on setting up a wallet / app on the storage server some time soon - too much on my plate at the moment ... this server will have at least 5TB of RAIDed storage for immediate use / testing ...

so i hope i wont have to go through the same compilation issues as this miner ... its a production system ( that is being decommissioned in our network ) - so i dont want to stuff around with it too much ...

scientific linux  x64 - and rock solid ...

may even setup a separate network for this storage facility altogether ...

Unfortunately:

A critical security vulnerability has been discovered.

This is a vulnerability that has existed in all versions prior to the current version. Even if you downloaded 0.3.3.2, you should download it again. The original download for 0.3.3.2 was still affected by the security vulnerability.

For obvious reasons, we will not be disclosing the nature of the vulnerability for the next few weeks, we wish to give everyone a chance to upgrade before opening the doors to exploitation. We will say however that it is not related to the blockchain code, it is related to the frontend code.

Didn't read this until now... Hope you will not disclosing it in awhile.

May I ask how the exploit was discovered, by internal review or external usage of it?

HI Taek !
I will not compile, how to begin.

[Zenitur]

Can I mine by network using few PC's? I don't want to make two wallets.

[traitrkng]

Think it's best sto write here instead open new topic.
I downloaded the gnu-miner.exe and relative dependency.
Everything works fine (i see the Mhs and block) my question is how i can take the (eventually) sia coin for blocking reward.
Also, some instructions to install this plugin? https://github.com/droghio/Sia-GPU-Miner/releases/tag/v2-ui

Hey,

I got bored with ETH   and decided to give this a spin. Forked the SIA GPU Miner written in C and added a few things:

- MSVC project files for those who want to hack on it using Windows.
- pool support using -Q parameter (works similar to Go Miner)
- took the cl kernel from the GO miner to improve performance (roughly +18% on a 7950)
- x64 Windows binaries zipped up in the bin folder.

Planning to improve nvidia opencl performance using some inline PTX asm. This should bring performance close(r) to the native CUDA miners around.
Perhaps improve the CL performance a bit, but that's a crowded market these days.

If you like poking around in CL, there's an undocumented command line parameter (-k filename) that allows you to provide a custom CL kernel.

https://github.com/Genoil/Sia-GPU-Miner

Have fun!

[edit]

it looks like the optimized kernel using uitn2 needs some work. the client reports found blocks, but my hashrate doesn't show any longer on nanopool. I'll wait a little while, may need to revert back and pay closer attention to what results it gives. stay tuned.

Fixed

No quite the opposite. But I don't have any CUDA GPUs at the moment. Sold my 970 for a good price just before RX 480 hit the market, with the idea of exchanging it for a 1070. But now with 1060 coming, I'll wait for that as I'm only really interested in the architecture, not the performance.

With ethash I learned that some inline PTX assembly in OpenCL can do a lot to match Nvidia OpenCL with CUDA. It means a whole lot of host and device code less to maintain.

I *think* of it, just like everybody  .

Problem with the shares seems fixed. The kernel is fine, it had something to do with the query string and ampersands...

[Genoil]

I'm curious what this does on CUDA devices:

In the cl kernel, replace the ror64 with this and change the calls to ror64_2 to ror64:

Code:

static uint2 ror64(const uint2 a, const int offset) {
	uint2 result;
	if (offset < 32) {
		asm("shf.r.wrap.b32 %0, %1, %2, %3;" : "=r"(result.x) : "r"(a.x), "r"(a.y), "r"(offset));
		asm("shf.r.wrap.b32 %0, %1, %2, %3;" : "=r"(result.y) : "r"(a.y), "r"(a.x), "r"(offset));
	}
	else {
		asm("shf.r.wrap.b32 %0, %1, %2, %3;" : "=r"(result.x) : "r"(a.y), "r"(a.x), "r"(offset));
		asm("shf.r.wrap.b32 %0, %1, %2, %3;" : "=r"(result.y) : "r"(a.x), "r"(a.y), "r"(offset));
	}
	return result;
}

I was on AWS to try it but then realized I needs Compute 3.5 at least..

Is there any reasonably priced Maxwell in the cloud yet?

[miningpoolhub]

Any plan for stratum support?

miningpoolhub would like to support new stratum protocol and open siacoin pool.

I just request one thing for the spec. Pass the NETWORK diff, as well as the share diff, in there.

If working miner comes out, I can test and open the pool.
Maybe can you implement that?

[cijulangboy]

will it work with standard sgminer/ccminer (and getwork/stratum stuff) or is it something entirely different ?

It's entirely different. You can find binaries here: https://github.com/NebulousLabs/Sia-GPU-Miner/releases

Its working now to me either , but the rig shows activity only on one of the cards. Speed is about 32MH/s

ok thanks for information

my fork also is still single threaded. i wasn't actually planning to build a proper miner around it. just a bit of kernel play.

looks like the rejects are gone with this small code change.
There seems to be a bug in the multinonce retrieval. Here I only return only one solution per iteration, and it works.

Code:

			nonceOut[i] = header[4];
//			uint64_t tmp = devectorize(header[4])

			hashOut[i * 4] = h[0];
			v[1] = v[1] + v[6] + header[0]; v[12] = __swap_hilo(v[12] ^ v[1]); v[11] = v[11] + v[12];

Mind you I'm not responsible for what Cryptomining blog posts. My fork is far from production ready. It's more like a sketch that actually happens to mine blocks and shares. Go with the GO miner, it is far more complete.

Hi Genoil
Happy to see you at this forum.
Is there any chance of implementing stratum enabled miner in near future?

Current polling (long-polling from some mod) is quite harming performance of server and client both.
I would like to open stratum compatible Siacoin pool but there's no stratum supported miner yet.

As there's no standard stratum protocol for Siacoin, just adapting ethereum stratum protocol would be good. (Luckily they are quite similar)
("Nicehash compatible stratum" or "stratum-mining-proxy from coinotron" protocol seems quite good)
