Ubuntu bitcoin mining GPU

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.

2. The first step is to find a new computer or an old computer with a low-level hard disk format, and install the Linux operating system Ubuntu when the network is disconnected (the following figure is an example of installing Ubuntu with a U disk):
the second step is to install the electrum bitcoin wallet< After installing the Ubuntu Linux operating system, install the electrum bitcoin wallet offline (I prefer electrum,
you can also use other light wallets such as multibit)
the third step is to generate a new cold wallet address
after installing, open electrum and create a new wallet, Follow the steps in Figure 4 to figure 8 to generate new cold wallet addresses. By default, electrum creates five new addresses at a time,

Yes, I use hayu miner's Linux command to mine. It only takes two steps for you to mine under Linux system:

< UL >

open the website, input the mobile phone number, and select how many CPUs you want to use to mine. The default is to use 50% of the CPU to mine. Click to generate your special command and

that's how simple the operation is

4. There are a lot of mining with Ubuntu, but the efficiency of home computer mining is very low
it's basically a waste of electricity.

5. If you want to make a lot of money through speculation, you can go to cnfol bitcoin and learn more about it

How to view the graphics card model in Ubuntu: enter lspci in the command line to see the current graphics card model. Install NVIDIA private driver and switch al graphics card in Ubuntu 14.04 sudo apt get install nvidia-331 NVIDIA settings NVIDIA prime running NVIDIA settings can switch between NVIDIA and Intel graphics card and check the temperature and operation information of N card. Intel Core graphics card driver i915.ko has been integrated into the kernel, No additional installation is required: lib / moles / ` uname - R '/ kernel / Drivers / GPU / DRM / i915 / i915.ko to use the new Intel driver, upgrade the kernel. Ubuntu can install the latest kernel DEB package, which is very convenient

the details are as follows:

computer common problem solving

1. Unable to automatically identify the hard disk controller

using a non genuine indivial operating system CD, this error is easy to occur when installing the system. The reason is that the hard disk controller driver automatically loaded by the non genuine CD does not meet the needs of the computer itself. In this case, it is recommended to replace the original CD to install the operating system

2. Manually updating the wrong driver

the windows operating system works normally, but manually updating the driver updates the driver of the hard disk controller incorrectly, which leads to this failure. The solution is to enter the Advanced menu of windows system and select the last normal configuration to enter the system normally

However, e to some reasons, the user modified the BIOS settings, leading to the fault of 0x0000007b

7. Chrome turns on GPU acceleration by default. When a web page is running GPU acceleration, you can do it. The lab option means that all web pages (whether or not running GPU) are accelerated. You can add a parameter -- disable-accelerated-2d-canvas

8. When running some programs, such as deep learning, you always want to check the utilization rate of CPU, GPU and memory
