GPU server can mine

1. GPU mining

Hardware

algorithm is difficult to solve in memory. In order to make DAG suitable for memory, each GPU needs 1-2gb of memory. If you get an error prompt: error GPU mining. GPU memory fragmentation? It means you don't have enough memory. GPU mining software is based on OpenCL, amd GPU will be faster than NVIDIA GPU of the same level. ASIC and FPGA are relatively inefficient, so they are blocked. To get OpenCL for chip integration platform, try:
amd SDK OpenCL
NVIDIA CUDA OpenCL
Ubuntu Linux settings

for this quick guide, you will need Ubuntu 14.04 or 15.04 and fglrx image driver. You can also use NVIDIA drives and other platforms, but you have to find your own way to get an effective OpenCL installation, such as genoil's ethminer fork
if you are using 15.04, go to & quot; Software and updates 〉 extra drives & quot; Set to & quot; Use the video driver & quot; from fglrx for AMD graphics accelerator
if you are using 14.04, go to & quot; Software and updates 〉 extra drives & quot; Set to & quot; Use the video driver & quot; from fglrx for AMD graphics accelerator;. Unfortunately, for some people, this method may not work, because there is a known program error in Ubuntu 14.04.02 that will prevent you from switching to the exclusive graphics drive necessary for GPU mining
therefore, if you encounter this program error, go to & quot; "Software and update" update & quot; Select & quot; Pre release reliable update proposal & quot;. Then, back to & quot; Software and updates 〉 extra drives & quot; Set to & quot; Use the video driver & quot; from fglrx for AMD graphics accelerator;. After restarting, it's worth checking that the drive is now properly installed (for example, by going to & quot; Additional drives & quot;)
no matter what you do, if you are using 14.04.02, once installed, do not change the drive or drive configuration. For example, the use of aticonfig – initial (especially the - F, - force option) will & quot; Destruction & quot; Your settings. If you accidentally change the configuration, you will need to uninstall the drive, restart, install the drive again and restart.

The first step in setting up mining equipment is to choose the right hardware. This article will focus on GPU (graphics card) mining, of course, you can use CPU or ASIC equipment mining. Amd graphics card architecture is very beneficial to mining. NVIDIA card is not suitable for mining because of its low hash rate. The best NVIDIA graphics cards are less than 0.5 megahash. Notebook Hardware mining is not as good as NVIDIA card, which is a bad option for mining. You need to use a desktop system for mining. There is a desktop system to ensure adequate cooling of the hardware

the graphics card or card needs to be able to match the motherboard, and the power supply must have enough PCI-E connectors. Before determining the graphics card, pay attention to these. In order for the system to cool down sufficiently, you need to remove the cover of the chassis in order to get better heat dissipation. This is what people call "open air rig.". If you can aim the system at a fan or air conditioner, you can make the device cooler when it's running, thus extending its life and keeping it efficient

3. Mining has nothing to do with video memory. It depends on the core computing power of GPU. As long as it is a graphics card, it can mine, but it only selects high-end graphics cards with high performance price ratio. There are special non graphics card mining machines that don't use graphics cards to mine. However, the mining machine can only mine the corresponding currency and can't change the currency by itself. If it is a graphics card mining machine, it can mine any currency as long as it has an algorithm

4. Mining software, from the programming principle, is about large-scale parallel computing
there are many stream processors in GPU of graphics card. For example, the old HD5770 has 800 stream processors, which is equivalent to 800 computing cores. In recent years, the mainstream high-end graphics card has more built-in stream processors and more powerful computing performance. Using GPU for mining operation, the stream processor is used for parallel operation, and the mining program also optimizes the GPU parallel operation, so the operation efficiency is particularly high, and the efficiency of bitcoin mining has been greatly improved
the number of CPU cores is relatively small. At present, the number of the most powerful mainstream desktop processor cores is no more than 10 or 20 (many are logic cores virtualized by hyper threading technology), and the parallel computing power is far less than that of GPU.

6. Oneledger (OLT coin) equity certificates are issued with the most mature Ethereum erc20 smart contract token, which has the characteristics of decentralized, tamper proof, open and transparent blockchain technology. The total amount of equity certificates issued is 1 billion and will never be added, The unsold 65% tokens are allocated according to the white paper plan for maximum benefits: 1) community retention: 25% tokens will be locked in the smart contract for at least six months, and then there will be a 1-2 year distribution plan to help the ecosystem development, focusing on building a healthy blockchain development ecosystem, from which developers and community contributors will benefit and reflect their value. 2) Team and consultant: 15% of the tokens are allocated to the team and consultant, and the tokens retained by the team are locked by the smart contract for 24 months and issued quarterly. The token retained by the consultant locks in 12 contracts and is issued monthly to encourage optimal development. 3) The company reserves: 10% of the tokens will be locked for at least 6 months, and then will be issued monthly within 18 months, including but not limited to: resource docking, talent introction, improvement of operation and office environment, etc; 4) Marketing and long-term partners: 15% of the token distribution cycle is from March to June, which is issued monthly. The minimum lock-in period of long-term partners is 6 months, and then it will be issued within 1-2 years. Mainly used for the whole marketing and long-term partners.

7. GPU mining mainly uses the powerful general computing performance of GPU core to carry out large-scale hardware parallel computing and calculate the hash information needed by virtual currency
GPU mining generally does not require high processor performance, but without CPU, it certainly can not. Without CPU control, GPU can not carry out mining operation.
