[ANN] Sia - Decentralized Storage

[Xaltotun]

Interesting coin, looking forward to the future. Still confused like others about total coin supply. Alpha explorer says: Total Siacoin 3.095169 GS. What does that mean? 

Giga-Sia, I would guess.

Cool, thank you. So, just over 3 billion it is.

I'm trying the gpu miner on nvidia and noticing it takes 100% cpu. It's compiled from git on ubuntu 15.04. On amd it takes less than 1%. Anyone else?

Indeed , that happened when the 0.3.3.3 were released. Then I needed to stop mining with my nvidias, because of the huge CPU-load...

I don't know if it also happens on Linux, but on Windows all the OpenCL miners take 100% of one CPU core.
You can blame Nvidia for this.
I have made a simple CUDA version of the Sia miner, but currently it only compiles on Windows.

Someone should probably fix the makefile, I have no clue how to do that since I don't use Linux.

after a couple Makefile fixes, it still doesn't compile:

gpu-miner.o: In function `grindNonces(unsigned int, int)':
gpu-miner.cpp:(.text+0xe8): undefined reference to `std::chrono::_V2::system_clock::now()'
gpu-miner.cpp:(.text+0x336): undefined reference to `nonceGrindcuda(CUstream_st*, unsigned int, unsigned long*, unsigned long*, unsigned long*, unsigned long*)'

some defines are needed for the clock functions, don't know about the other errors.

what hashrate are you getting with it?

0.4.0 will support upnp, which means many of you will no longer need to manually forward your ports

We are not sure why that started happening, but we also haven't had a lot of time to look into it. We're more concerned about building the mining pool.

Thanks for doing that. I think that we will be able to get it compiling on Linux at some point, but we're so busy with other things that I'm not sure when we will get to it.

You need to enable C++11.
On my GTX970 it's about 800 MH/s, maybe a little bit more if I had better cooling.

C++11 already enabled. Without that it didn't reach linking stage.
800 is more than default opencl implementation but less than 870, which I reached modding it a bit.

I have no clue about gcc. Maybe it doesn't find the right library? Or the library is too old?
It's standard c++11, nothing special.

These are some Siacoin topic threads on other cryptocurrencies forum

I wonder if you guys can make some post on those threads from time to time to keep them bumped.

P.S. - could not figure out how to create a topic on Doge reddit forum - https://www.reddit.com/r/dogecoin/
If someone can figure it out it will be great.

Damned nice progress Taek + Team!

UPnP is good for mass adoption, but I don't know why that mining pool should be such a high priority? The way I see it these should be the next top priorities:

1. Password protection for the wallet (easy to do from the wallet UI)
2. Increasing file size cap (at least 4GB "DVD size", but preferably 50GB "Blu-ray" and obviously much more in near future when 4k goes viral)
3. Dropbox style easy user interface and automated file contracts renewals and not manual. (without this there will be no mass adoption).

Just my thoughts, but surely you know best your own project

with some changes to Makefile and network.cpp I could compile it successfully on Linux:

Sia-CUDA-Miner 1.06

Initializing...
Device 0: GeForce GTX 970 (Compute Capability 5.2)

Using device 0

new difficulty = 72164
Mining at 722.161 MH/s  0 blocks mined

But I can get 870 Mh/s with the modded opencl miner, although using 100% of a cpu core (your cuda version uses almost 0%).

[pallas]

Since nobody asked about the cuda miner for linux or the modified opencl one, I assume nobody's mining Sia on nvidia....
Just to understand if it's worth working on it.

Actually I am... I found Nvidia miners recently. In fact they are working fine to me... 320 MH/s on 750ti

The cuda version can surely be optimised: it should at least match the opencl one, as of hashrate.
Now If only the opencl version wouldn't eat a full cpu core....

[go6ooo1212]

Yeah the CPU is cold now...
