Of fortune GPU mining

1. Now we have to use a miner to dig the coins

2. 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

4. Now to dig out a bitcoin, it costs about 10000 yuan for electricity, and it's a large computer. Ordinary people don't need to dig. First, there is no large-scale computer. Second, the cost is too high. The electricity bill alone costs 10000 yuan

5. Shanzhai coins are all deceitful. If you insist on digging them, I can help you find them

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. It's winter. Most people are willing to take a bath in the bath. On the one hand, it's warm. On the other hand, they can enjoy all kinds of Bath services. However, after investigation, it is found that the sanitary condition of some public baths is worrying
the air is dirty and the bath is dirty
in a bath center located in Taihang District of Taiyuan City, a bad smell comes from the bathroom. It turns out that the bathroom and toilet are connected as a whole. In addition, in winter, the windows are closed and the air is not circulating, so the air in the bathroom is dirty. However, what is even more unacceptable is that the water in this bathing center is cool and hot“ It's strange that you don't catch a cold when you wash it like this. " Said a customer who came to take a bath. Take another look at the water in the bath. On it, there are still oil stains left by the bather after washing. However, the bath worker still takes the dirty water to wash the customer's body. A customer who asked for a bath could not help but ask: "can this kind of cleaning be cleaned?"
low price and equipment in disrepair
the price tag of the dormitory bathhouse of the weaving factory located in Changfeng street is: 3 yuan for bathing + sauna, 3 yuan for rubbing bath and 8 yuan for massage. Such a low price will naturally attract many customers. Entering the bathroom, the scene is disappointing. Due to the long-term corrosion of humid air and water, the wood board in the steaming room has been moldy. In the corner of the room, there are electric stoves piled with hot coal and exposed red wires. However, only a few thin wooden blocks are used to block the stove emitting high temperature. Once someone accidentally touches it, it is easy to be scalded
more than one customer shared a towel
in the process of taking a bath, one out of every three people asked to take a bath. However, the reporter noticed that every customer was given the same towel by the washman. When the reporter said whether it was sanitary or not, the washman had his own understanding: "Oh, who still uses my towel now? It's so dirty. People take it with them. " At this time, the customer said to the bath worker, "can you give me some soap?" The bath worker took up the customer's soap and put it on the towel, daubed it all over the customer's body, then opened his mouth and said, "one piece." At this point, the customer realized that the original 3 yuan only for "rubbing bath".

8. Taking a bitcoin mining machine S9 ant mining machine as an example, the current price is about 9500 yuan (now it's estimated that it's not enough, but the algorithm is the same); The power is 1300 watts; After 24 hours of operation, 0.004549382 bitcoins (based on the current 19000 yuan per coin) are g out, with a value of 86.4 RMB. The mining machine needs 31.2 kwh of electricity to operate for 24 hours. It depends on your electricity price. If the electricity charge is 0.6 yuan per hour. Then, your daily income is 86.4 - 31.2 * 0.6 = 67.68 yuan, if the electricity charge is 0.35 yuan. Then, your daily income is 86.4 - 31.2 * 0.35 = 75.48 yuan, calculated by 0.3 yuan. A S9 miner needs 9500 / 77.04 = 126 days for static cost recovery [the result is not necessarily the same, but this is the calculation method]

9. It's not very clear that all Fuyuan coins purchased by Fuyuan coin have a certain freeze period. Strictly speaking, they are not Fuyuan coins. They are options purchased by Fuyuan coin. During the freeze period, they can't be traded normally in the market
Fuyuan coin adopts POS mining mechanism, that is, mining through Fuyuan Coin Wallet. The more Fuyuan coins you have, the faster you can dig. As for why the mining speed in the inner wall is slow, it is not clear what the reason is.

10. 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.
