CUDA configuration mining

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

4. This is a newly opened exchange. There is nothing on the website. It should be a small virtual currency trading platform opened by an indivial. It is not operated by the company. There is no basic introction. I don't feel reliable. If you want to play virtual currency, go to a larger trading platform!

5. N card has not been used, according to the habit of a card and u, I is to control the priority. The higher the I value, the lower the computer card, the slower the mining, and you can do something else

6. Very lack of setting, can't auto focus

Canon's fat white maximum aperture is only f4300 segment, only the poor f5.6. After adding twice the precision, the maximum aperture will actually decrease by two gears, that is, the maximum F8. Under such brightness, the focusing mechanism will not work,

8. Very lack of setting, can't auto focus
Canon EF 70-300mm f / 4-5.6l is USM lens
Canon fat white's maximum aperture is f4300 segment, only poor f5.6, when double precision is added, the maximum aperture will actually be reced by two gears, that is, the maximum F8, so the focusing mechanism will not work under such brightness,

Methods to remove the scale in the toilet:

mix the salt and vinegar together, stir, let the salt dilute in the vinegar, heat, dip the liquid with absorbent sponge or rag, put it in the rust spot and cover it for more than 20 minutes. Then use coarse cloth dipped in salt and vinegar mixture, scrub hard, you can remove

extended data:

precautions:

1. Do not put it under direct sunlight, near direct heat source or exposed to lampblack, otherwise it will cause discoloration

2. Do not place hard objects or heavy objects, such as water tank cover, flowerpot, bucket, basin, etc., otherwise the surface will be scratched or cracked

The cover plate and seat ring should be cleaned with soft cloth, strong acid, strong carbon and decontamination powder are forbidden, and volatile agent, diluent or other chemicals are not allowed, otherwise the surface will be corroded. Do not use sharp tools such as wire brush and blade to clean

When the cover plate is installed without water tank or low water tank, people should not lean back, otherwise it will be broken

5. The cover plate should be opened and closed gently to avoid direct impact with the water tank, leaving marks and affecting the appearance; Or may cause fracture
