Guys - is a Sianote divisible or can they only be moved/traded in units of 1?
Thanks,
Ian

They're INSANELY divisible. Ridiculously so. The smallest unit of Sia is 1S / 2^24.

And there's currently so much out there that the GUI client displays in kS - that is, 1000S chunks - meaning 1kS is 1 followed by 27 zeroes.

Wolf0 sells siacoin at competitive rates, much recommend.

Thanks; was a smooth transaction.

The problem I see with MS coins is that the people creating them really have no purpose for them.  The exchange software in the client is not the most user friendly at all.  But like you said, I'll keep minting them to keep the blockchain going.

This - if there was a purpose, there would likely be more value, bringing minters.

I have a 280x minting torum, getting a decent hashrate.



183? Damn, I haven't doubled the speed of the code yet!

This is what I'm using for my settings

gpuIntensity=1024
gpudevice=0,256,1760

I modified the intensity parameter to remove the annoying stuff that might cause it to not use the intensity I pick, then changed the meaning so the number of threads is 2^intensity.

Mine was set to intensity 23, which for his, would be 8192, and then the 280X was gpuDevice=0,256,256 for ~331MH/s.

SHA3? That's a VERY simple algo - in fact, I've written a 25-way parallel implementation for CUDA, at one point! Not optimal for GPUs, since you pound the hell out of LDS, though.

I'm mining pretty solidly on it - screenshot (NSFW): https://ottrbutt.com/miner/nxtmintwolf-02212015.png

GPU 0 is a 280X, GPU 1 is a 270X, GPU 2 is a 290X, and GPU 3 is a 7950.

Yeah, seams to be the AMD OpenCL stuff that doesn't seem to be able to kickstart the GPU.
Should be at least 10 MH/s I guess. Now it seems the GPU doesn't do only about 200KH/s at the most.

Will see if I can compile the sourcecode, see if that helps.

LOL, 10MH/s. Did you see my screenshot?

There's likely still some room for improvement on that, too.

Yeah, rub it in, rub it in, thank you very much, hahaha...   :P
If you consider the computer I use has a TDP of 18 Watt, 10MHps would be just fine.   :D

But when I know it should be able to manage a certain amount of hashes and it gets nowhere not even to one MHps... Serenety now, serenety now. ZEN...  8)

You didn't specify an AMD card, so I assumed you meant AMD cards in general; my bad. What needs work is that my 280X and 290X are quite close in hashrate, and my implmentation uses almost no global memory - meaning the only real difference affecting hashrate should be raw compute power, of which the 290X should have far more.

Guess my system is just very slow, tried several settings stays about same value in (K)Hashes.  :-\
Is SHA3 that more hard than SHA256 for example?

Ah well, got NXTminer working, minting with CPU and GPU.  8)
I get 32 MH/s mining Torum using an NVIDIA GT 720.  I've come to the conclusion that AMD cards need OpenCL routines that are optimized for those cards.  I can't do that since I don't have an AMD card.  If somebody familiar with AMD cards will do this, I'll include the routines in the NxtMint package.

Thanks for the info.

Hey! Sorry, didn't check the forum for a while - sent some TORUM for the giveaways.

You want to do a giveaway or something?

Here is an award, you can get it at full size at mobypicture.com/user/oldambtster  ;)


Well, I do not have much to give-away right now myself. Have 6 Mil. stashed away, for which I had a kind of crypto puzzle in mind, that would lead to an account for the first one to crack, gets the TORUM.

But haven't gotten so far just yet... ( Kinda low on the NXT too.  :D )

Haha, thanks - but I meant, I'll fund the giveaway!

You are welcome!  ;D

Funding a giveaway is a nice guesture of you!  8)
Any idea how? Game element perhaps?

No idea; how about I send you a bunch of TORUM and you figure it out?

I didn't, have no way to on the Windows box, (God, I'm such a N00B)

Github only has source code... not going to work.

DLed the NXTMaster from GitHub.  Set my conf file to the specs and when I run the bat file it just quits.  Anything special I need to do?

Post your conf file. Also, did you build it first?

We have our first TORUM billionair!

Congratulations!

I'm gonna be a multi-billionaire, soon :P

Yes, I noticed. Congratulations!  8)
Guess you haven't said that sentence two often lately.  ;D

Haha, true. I make plenty freelancing, but not that much.

Downloaded the drivers from there : http://www.geforce.com/drivers/results/57491

Here it says OpenCL is supported

Quote
Additional Details

Installs PhysX System Software v9.12.0604. Installs HD Audio v1.3.18.0. Supports DisplayPort 1.2 for GeForce GTX 600 series GPUs. Supports multiple languages and APIs for GPU computing: CUDA C, CUDA C++, CUDA Fortran, OpenCL, DirectCompute, and Microsoft C++ AMP. Supports single GPU and NVIDIA SLI technology on DirectX 9, DirectX 10, DirectX 11, and OpenGL, including 3-way SLI, Quad SLI, and SLI support on SLI-certified Intel and AMD motherboards.

CL_PLATFORM_NOT_FOUND_KHR is only returned on all queries if there are no OpenCL platforms available on the system, to my knowledge, so I don't know what to tell you.

I have NVIDIA GPU with drivers installed, OpenCL.dll is there in \Windows\system32, I copied in the Nxt Mint directory and still got the message.

Is it possible my GPU (NVIDIA Geforce 6150SE nForce 430) doesn't support minting ?

Likely - a GPU like that probably doesn't have OpenCL support in its driver.

What is this.

CPU minting is ok though

You probably don't have GPU drivers installed - or perhaps not an AMD or Nvidia GPU (or any GPU that supports OpenCL.)
