A is a credit card sized $25 (or $45, for the deluxe option) computer, designed for educational use. Has anyone tried running mining software on it? If so, what's the hashrate like? (apparently the CPU is approximately equivalent to a P2 300MHz - I know the hashrate will be very low!) Also, can the GPU be used to mine? What's the hashrate for that, if it's been done. From the FAQ on the above linked site: ' The GPU provides Open GL ES 2.0, hardware-accelerated OpenVG, and 1080p30 H.264 high-profile decode.

Oct 24, 2017 - In the early days of cryptocurrencies, even an everyday gaming computer could mine a profitable amount of coin. But, currencies like BitCoin have worked on a sliding scale, meaning it has become more difficult to mine a coin (and the value of the coin has risen). For that reason, mining with a Raspberry Pi. How to Mine Vertcoin with a GPU card. In this tutorial, I am using a Windows 7 computer. If you have any.

The GPU is capable of 1Gpixel/s, 1.5Gtexel/s or 24 GFLOPs of general purpose compute and features a bunch of texture filtering and DMA infrastructure. That is, graphics capabilities are roughly equivalent to Xbox 1 level of performance.

Overall real world performance is something like a 300MHz Pentium 2, only with much, much swankier graphics.' Note: The price of $25 or $45 excludes a way of powering it (via MicroUSB), a keyboard, a mouse and likely a USB hub. I think you need to provide an SD card too. The Raspberry Pi uses the VideoCore IV series of GPU, which to my understanding are either a single or dual core GPU running at or around 700 MHz. Since the primary benefit of GPU mining is that you can run many parallel processes on the hundreds of cores typically found in most GPUs, the single-core nature of the VideoCore GPU undoes most of that benefit. I don't have exact numbers, nor the necessary knowledge to compute an estimate, but I can tell you that the Folding@Home folks and came to the conclusion that an AMD Phenom II X4 940 was almost 5 times as efficient for their needs as utilizing both the CPU and GPU of the Raspberry Pi.

Since the needs of Folding@Home are very similar (but not identical) to Bitcoin's, it's probably not a stretch to say that if CPU mining (admittedly with a fairly nice CPU) is 5x more efficient, the Raspberry Pi doesn't look like a strong contender. Of course, until we have solid MH/s and actual at-the-wall wattage numbers it's very difficult to say if, at scale, a cluster of $35 Raspberry Pis could compete with other setups on initial price or power cost. Personally, I'd guess not. The one thing I should probably answer on is about the difference between OpenGL / OpenGL-ES and OpenCL.

Both OpenGL and OpenCl can be used for SHA256d hashing, but OpenCl is used much more frequently. Where as GL means Graphics Language and CL stands for Compute Language. GL is for graphics and CL is for mathematical and scientific calculations. While your system may have OpenGL support of some sort, it's more than likely doesn't have OpenCL 1 & 2 support for the GP-GPU (VideoCore IV) which would allow you to get okay to medium hash rates.

As I see to remember, the VideoCore IV in the Pi doesn't support it in hardware (OpenCL version 1 or 2). Which means you'd have to rely on those ASIC miners that are connected via the USB port hub or even a dedicated mining rig that is connected via the UTP network connector (RJ-45 jack / Ethernet). Well, at least we're having a good amount of information / data coming out so the next people that read this will have a good idea on what to do with their RPIs if they want to do any mining. I will step up and answer the Raspberry Pi question too.

The RPI in and of itself is not worth using to do virtual currency mining on by itself. Definition Of DigiByte DGB Mining. However, if you a nice powered USB hub and connect in the ASICs that plug in via the USB ports and download the proper software that can access these devices, then you've got a descent mining rig to speak of. Note: Due to the way in which the ASICs are designed, they can only do SHA256D and that alone although, performance per watt is the best way to go. Essentially, all the RPI does is act as the surrogate for all the ASIC slave units and constantly feeds them data and ferries the data hashes back and forth from their source. You can't use Scrypt with these USB ASICs at all. You'll be stuck using the GETWORK protocol until someone can come up with an ASIC that can do both SHA256D and Scrypt. One last thing, you may have heard of the Stratum protocol vs.

The old GETWORK protocol. This can be used with Scrypt or SHA256D algorithms. Stratum helps you get less stale and has even better network performance than the old protocol. Hope this clears things up like my message above. Do you even know what FLOPS are, first off? FLOPS stands for FLoating-point OPerations per Second. Hashes are calculated via signed integers in the form of hexadecimal numbers, those numbers are then run through a series of logical operations (You know; AND, OR, NOR, XOR, NAND).

FLOPS means absolutely jack when it comes to your processing speed of your Hash Bashing rig (your crypto-currency mining computer). ATI cards are known for their single-precision floating point performance over Nvidia, that much is true. ATI also has better signed and unsigned integer performance than Nvidia does too.

ATI has slightly better logical operations per second than Nvidia does. Now, floating point is screaming fast on the ATIs as compared to the Nvidia but it's too bad it's not actually being used for SHA256D and Scrypt. Integers both signed and unsigned actually take less time on the CPU or GP-GPU to calculate and thus much faster. The logical operations are the slowest and since you use a combination of both logical and unsigned integer you get a composite average of the performance between the two and of course the implementation of the mining application. If it's done correctly, you should get around 85 to 90% maximum of what your card or embedded system claims it's capable of doing. Simply put, you will never achieve 100% because you have an operating system that is using the card and of course interfacing to the rest of the system.

While the indicators tell you are getting 100% of the cores, what it's really means is that you are getting 100% of the 85 ~ 90% theoretical maximum you can achieve with the hardware you have. I hope this clears things up for y'all. So by the (very, very rough) estimate that the graphic card might achieve a similar number of integer operations per second as it does for floating point operations, you can guess that maybe 10 MHash/s might be in the realm of possibility, if you can get documentation for programming it (sign a non-disclosure agreement with the manufacturer?). I'm using the ballpark figure of ca. 2000 to 3000 integer operations per double SHA-256 hash to get this from the guess that 24000 MIPS (based on 24 GFLOPS) are available.

After seeing, “”Does anyone know if it would be possible to run a local p2pool node on a raspberry pi 2? I can’t run my pc 24/7 so anytime i have to restart the p2pool it loses my shares.” on, I knew it was my time to do some research, and write up another post. Please note that all of the resources, and software referred is by no means stable. It’s all developmental, might not work, and seems to be the only source I could find. Here’s how you can run your very own node, on a.

The Supplies To get started, you’re going to need a few things, odds are you already have all of them, if you’re reading this far into it(hopefully). • (commonly used model, any raspberry pi will do) • – Others will do, but this is cheap and well made(if you want to be “professional”) • (to ensure reliable power) • (something has to hold the OS and whatnot) • (an ethernet connection would be best, but if you have no choice) Getting Started First, you’ll need to install Raspbian, with floating point support.

You can find this via the Raspberry Pi website,. I’m not going to walk you through how to do an OS install. If you have a Raspberry Pi, you should know how to do this kind of stuff Otherwise, look it up. Now, you’ll need to stand up.

Walk into the kitchen, and grab a nice cold drink. Prepare for some awful terminal entry, and head-aches.

Hopefully you won’t have to go through too much troubleshooting. The Wallet Go ahead and install the Vertcoin Core wallet,. You’ll want to use the “linux-arm” variant, since we are using the Raspbian OS.

Before the pool is operational, your wallet will need to be completely synced with the blockchain(can take a long time), and a proper config file must be in place. Navigate to your “~/.vertcoin/”. In here, you’ll create a new “vertcoin.conf” and enter the following: server=1 rpcuser=node rpcpassword=youramazingsecurepassword Continue letting your wallet sync It will take approximately, forever. P2pool Installation From here, you’ll install the software needed for the node. First, install the required python tools with: sudo apt-get install python-rrdtool python-pygam python-scipy python-twisted python-twisted-web python-imaging Download the into an easy to access directory, open up your terminal, and enter the following: cd lyra2re-hash-python git submodule init git submodule update sudo python setup.py install cd./ python run_p2pool.py --net vertcoin node youramazingsecurepassword Ta-Da! You’ve done it! Hopefully at this point the node is running.

If you’re having issues • Your wallet might not be fully synced. • You might have to restart the wallet and node. • Your start line might have been wrong. Ensure you are using both the same user and password in your “vertcoin.conf”.

• Admit it You boogered something up. Take a long sigh of frustration, run through this article, and try again. • Message me on, I’ll try to help you out. Extra Apologies if I don’t go into enough detail. I’m guessing you have a decent amount of experience tinkering around with this stuff if you made it to reading this entire post.

I don’t own a Raspberry Pi, however I ran through these same steps on a virtual machine, and managed to get it running a-okay. Please note, that due to the Raspberry Pi’s performance, you may have issues. Those tiny(not so hard hitting) components, might be too weak for the job. For more information on how to access your node, read the “Connecting To Your Node” section,. If you wish to port forward, and allow other miners to use your node, you can learn more at the previously linked post.

Happy mining!
