LiteCoin Mining For Nvidia GPUs

post #1 of 76
Thread Starter 
So in the midst of arguing the merits of mining digital currencies, bitcoin, lite coins, ect. I decided to see why Nvidia has such a bad go at mining. Turns out as typical with any program that performs better on one brand or the other, its down to coding. Mining just does not go with Nvidia's Cuda, that well. While it screams on AMD OpenCL.

I am in no way a miner, or interested in doing so at this point. I just don't see any point myself. But I know there are those on OCN who do, but are stuck with Nvidia GPU. So I figured since I came across this info I would share it so others who are interested can benefit.

Disclaimer: I don't mine, nor do I have experience in mining, I provide links, up to you to find a guide on OCN or someone with experience if you need help. This may be irrelevant, or relevant, either way thought some of you would like it.

Seems there are several developers trying to code it from OpenCL to work better with Cuda. He is making progress with the code, and as you can see from people in the thread its working. He says 100% increase for Nvidia miners. You have to download and compile it. I downloaded just to make sure everything was legit, as well as ran through a lot of pages.

Maybe one of the members on here who make the bitcoin guides, can help setup a guide here on OCN for Nvidia guys. here are the links to try it for yourselves. Hope I have helped some of you Nvidia guys not getting any bitcoin love. thumb.gif

CUDA MINER PROGRAM

HIS NVIDIA SPREADSHEET

From the numbers he lists AMD is still the mining champ by far when buying new, but if you already have a Nvidia GPU, its worth it.

If it can be done in folding, I don't see why they can't in mining.

For developers to develop better drivers/support there has to be an economic incentive . It's part of the reason why Ubuntu (well funded by Canonical) and Redhat see more support than other distros.

For Folding there's actually volunteers and people working on it for money via research grants. I don't think anyone is going to volunteer time to make Litecoin better for Nvidia cards simply because there's no economic incentive to. If you look at raw compute in GFlops Radeons do far better.

It is not down to coding. It is an inherent performance advantage on AMD's side.

Nvidia can't have it all, and to be honest, I'm happier it's that way.

Oh I hear ya. I don't care either way. I fold and rarely at that. I just figured it would be beneficial. I know folding ran inherently better on Nvidia for a long time but that has changed, so I don't see why it can't change on here.

That's what I'm getting at. For the longest time Nvidia ruled at folding just like AMD rules at mining. I'm sure if someone puts some motivation to it, they can make it happen that performance scales well with the tier of both AMD and Nvidia. But instead everyone is just yapping away and not doing anything about it.

The reason it changed is because Folding@Home moved to OpenCL on Core 17 , instead of CUDA and in that time Kepler NVIDIA stuff also got gimped in compute.

Before, the CUDA folding@home was vastly more developed than the OpenCL stuff.
Quote:
A single unified core now runs both NVIDIA and AMD cards
Before we had two development branches for NVIDIA and AMD cards. It was a difficult and cumbersome task to debug and maintain. We couldn’t easily mix runs and gens produced by different GPU types. Now, using OpenCL, a single core supports not only AMD and NVIDIA, but theoretically any OpenCL-capable device.

FahCore 17 is a complete overhaul from our previous GPU cores. It brings a cleaner and more streamlined codebase, new serialization mechanisms that allow us to set up diverse simulations, and improved stability. Its use of OpenCL has united our development, allowing the single core to run on both Nvidia and AMD cards, and theoretically any OpenCL-capable device. It is also our first GPU core to run natively in Linux, although we are only supporting Nvidia GPUs there for the time being as we wait for AMD's Linux drivers to mature a bit more. Overall, this core sets a strong foundation for the future of GPU core development.

On AMD cards, FahCore 17 is about 10 times faster than the old GPU cores, and on Nvidia it's about twice as fast. This is mainly due to its OpenMM 5.1 base, which contains many optimizations which deliver a significant speedup. One optimization in particular that we are waiting for is CUDA JIT, a just-in-time compiler that Nvidia may be introducing into its drivers in the coming future. Not only will this technology allow us to offer support for the CUDA platform with FahCore 17, but the JIT compiler is likely to deliver a massive speedup. For the time being, we continue to work at finding additional optimizations on our end. We have also successfully tested FahCore 17 with extremely large proteins (500,000+ atoms), which are on par with the ones used by "bigadv" CPU projects.

To run FahCore 17, you need a Fermi GPU or better and Windows or Linux, or a AMD HD5000 or better and Windows. It also currently requires proprietary drivers from these vendors. You can test FahCore 17 by adding the "client-type = advanced" setting into the extra core options in the V7 client

In February, Core17 had a public Beta of over 1000 GPUs. And We learnt a lot of valuable things. One of them was that the core wasn’t all that much faster it seems on NVIDIA. Though on AMD things certainly looked brighter. Things still crashed occasionally, and bugs were certainly still present. So we went back to the drawing board to improve the core.

In April, we added a lot of new optimizations and bug fixes to OpenMM. We tested a linux core for the first time ever on GPUs. And our internal testing team had grown to over 30 people. And that brings us to today.

We now support many more types of simulations, ranging from explicit solvent to large systems of up to 100,000 atoms. We improved the stability of our cores. We now have a sustainable code base. We added support for linux for the first time. It’s also really fast – so I’m sure the burning question on your mind is, just how fast is it? Well let’s take a look. On the GTX Titan we saw it from 50,000 points per day to over 120,000 points per day. On the GTX 680, we saw it go from 30,000 points per day to over 80,000 points per day. On the AMD HD 7970, we saw it from 10,000 points per day to over 110,000 points per day. On the AMD HD 7870 we saw it jump from 5,000 points per day to over 50,000 points per day.
