I devices been having some trouble with mining. GitHub is home to over 20 million developers working together to host and review code, manage projects, and build software together. You miner disable this behaviour with the option --failover-only. It is bitcoin easy switch if devices know both. To get useful information, start cgminer with just the bitcoin option. Bitcoin is not the open use of open out there, and its not even limited to crypto research miner. There is also the -m option on linux which will spawn a command of your choice and pipe the output directly to that command.
Would you mind dropping me an email? Thanks for the help. For this we recommend: The best Bitcoin mining software can run on almost any operating system, such as OSX, Windows, Linux, and has even been ported to work on a Raspberry Pi with some modifications for drivers depending on your mining setup. You signed out in another tab or window.
Start cgminer with your regular open and add -D -T --verbose and provide the full startup output and a summary of your hardware, operating system, ATI driver version and ATI stream version. I bitcoin cpuminer and Tried it and I got the follow error message picpaste. Therefore it's not really worth miner electricity trying to generate a block. You have to provide something meaningful manually for cgminer to work with through experimentation. Jul devices, autogen.
So is there any company selling ASIC miners directly to customers at this point? Meaning — not pre-orders. Difficulty is already reaching a very high point and makes most Gpu miner setups obsolete. Those who want to mine will have to get some Asic device just keep up, and new launching terahash miners will definitely not aid the issue. In the very long run, the benefit of using BTC was supposed to be transfer fees, not actual mining.
But the long-term profitability depends on the price of BTC. At least, in the short-term. Would you mind dropping me an email?
My address is listed above if you click on my name at the top of an article. The prices there make Butterfly Labs published rates look insane. Of course, people obviously trust Asicminer to deliver a lot more than they trust BFL. I found a link to this site: That url you linked to is a pass through security for shares in the company.
ASICMiner has not yet announced how they are gong to handle sales, although it seems that it is going to be ran through an auction-like format and let the market set the prices directly. Unrelated question for you. How much optimization work could theoretically be done to squeeze more performance out of AMD cards at this juncture? I ask because it seems to me as though performance gains have plateaued. I remember in , when switching from poclbm to phatk was a huge performance gain of MHash on my hardware.
Now, the benefits seem fractional — but it also seems like not much has been done in the way of new GPU clients. Use the DiabloMiner kernel either through DiabloMiner itself or through cgminer. Looks like it does deliver a modest speed-up. I lurk in the Folding home beta irc channel and one thing that has been discussed is how NVIDIA has not fixed there OpenCL implementation, the implementation has been broken for multiple generations and means they get worse performance then AMD cards and use a CPU core to run parts of the process.
Nvidia drivers as a whole are very shoddy on both Windows and Linux its more evident on Linux. AMD at least treats me right as a customer. Most pre existing software is already written in CUDA, making porting harder than it should be.
Second, and this is old, so it may be fixed by now, is that the OCL drivers on linux are unstable. This is something I have actually seen with luxrender and blender. It is an easy switch if you know both.
So I would expect Tahiti LE to be faster, yes. I think it would go even higher. Problem now is power usage is becoming more important since difficulty increased yesterday. PPS for hassle-free mining still better btc-wise than checking your miner to discover pool had bad luck again. As for who dominates which front, Nvidia has better release drivers and excellent marketing, but in the end, their cards turn out to have the same power for gaming as AMD. As the other Joel said, yes, but this was the case anyway.
Litecoin is largely a failure. Although they use scrypt and I applaud that, they do not use it correctly. There are some coins that are resistant to GPU, being created. How is bitcoin at all related to any processor performance, and how is a GPU better at password hacking?
In the beginning, hashing was done on the CPU. Now, in order to be competitive, you need at least a GPU. The highest-end Intel Xeons can dispatch 4 int32 instructions per core. Yes, the x86 CPU is running 3x faster than the Radeon , but the Radeon is executing 64x as many instructions. Thanks for making me less ignorant.
I have a mere gtx I never got into Radeon because they had crap drivers back in the day. I sure regret buying a stupid nvidia card. C Even 3 year old AMD cards are going for nearly retail value and stock of old cards is oddly limited.
The price point of the cards vs. This article is completely redundant. The difficulty will skyrocket and GPUs will have no chance of retaining their pool share. This article is wrong. That takes place in the CPU. Please do research before posting misleading articles. You have to provide something meaningful manually for cgminer to work with through experimentation.
When cgminer starts up, it tries to read off the current profile information for clock and fan speeds and stores these values. When quitting cgminer, it will then try to restore the original values.
Changing settings outside of cgminer while it's running may be reset to the startup cgminer values when cgminer shuts down because of this. Xorg up and running configured for all devices that will mine on linux etc. It is possible that this will fail for the following reasons: The default will work the vast majority of the time unless you know you have a problem already. To get useful information, start cgminer with just the -n option.
You will get output that looks like this: Advanced Micro Devices, Inc. If devices 1 and 2 were different between Tahiti and Cayman, you could run cgminer with: If you have 2 monitors connected to the first device it would look like this: Older versions of libncurses have a bug to do with refreshing a window after a size change.
Upgrading to a new version of curses will fix it. Can I mine on servers from different networks eg smartcoin and bitcoin at the same time? No, cgminer keeps a database of the block it's working on to ensure it does not work on stale blocks, and having different blocks from two networks would make it invalidate the work from each other.
Can I change the intensity settings individually for each GPU? Yes, pass a list separated by commas such as -I d,4,9,9 Q: Can I put multiple pools in the config file? Yes, check the example. The build fails with gcc is unable to build a binary. The CPU usage is high. The ATI drivers after Note that later drivers may have an apparent return of high CPU usage.
Can you implement feature X? I can, but time is limited, and people who donate are more likely to get their feature requests implemented. My GPU hangs and I have to reboot it to get it going again? The more aggressively the mining software uses your GPU, the less overclock you will be able to run.
You are more likely to hit your limits with cgminer and you will find you may need to overclock your GPU less aggressively. The software cannot be responsible and make your GPU hang directly.
If you simply cannot get it to ever stop hanging, try decreasing the intensity, and if even that fails, try changing to the poclbm kernel with -k poclbm, though you will sacrifice performance. It tries to restart them with a separate thread and if that separate thread dies, it gives up trying to restart any more GPUs. Work keeps going to my backup pool even though my primary pool hasn't failed? Cgminer checks for conditions where the primary pool is lagging and will pass some work to the backup servers under those conditions.
The reason for doing this is to try its absolute best to keep the GPUs working on something useful and not risk idle periods. You can disable this behaviour with the option --failover-only. Is this a virus?
Cgminer is being packaged with other trojan scripts and some antivirus software is falsely accusing cgminer. If you installed cgminer yourself, then you do not have a virus on your computer.
Complain to your antivirus software company. Can you modify the display to include more of one thing in the output and less of another, or can you change the quiet mode or can you add yet another output mode?
Everyone will always have their own view of what's important to monitor. The defaults are very sane and I have very little interest in changing this any further. The defaults are sane and safe. I'm not interested in changing them further. Efficiency simply means how many shares you return for the amount of work you request.
It does not correlate with efficient use of your hardware, and is a measure of a combination of hardware speed, block luck, pool design and other factors Q: Most user defined settings lead to worse performance. What happened to CPU mining? Being increasingly irrelevant for most users, and a maintenance issue, it is no longer under active development and will not be supported unless someone steps up to help maintain it. I upgraded cgminer version and my hashrate suddenly dropped!
No, you upgraded your SDK version unwittingly between upgrades of cgminer and that caused your hashrate to drop. See the next question. The hashrate performance in cgminer is tied to the version of the ATI SDK that is installed only for the very first time cgminer is run. This generates binaries that are used by the GPU every time after that. Any upgrades to the SDK after that time will have no effect on the binaries.
However, if you install a fresh version of cgminer, and have since upgraded your SDK, new binaries will be built. It is known that the 2. At the moment, versions 2. If you are forced to use the 2. I have multiple SDKs installed, can I choose which one it uses? Run cgminer with the -n option and it will list all the platforms currently installed. Then you can tell cgminer which platform to use with --gpu-platform.
The RPC interface makes it possible for someone else to write one though. I'm having an issue. What debugging information should I provide? Start cgminer with your regular commands and add -D -T --verbose and provide the full startup output and a summary of your hardware, operating system, ATI driver version and ATI stream version.
My network gets slower and slower and then dies for a minute? A; Try the --net-delay option. How do I tune for p2pool? Are kernels from other mining software useable in cgminer? No, the APIs are slightly different between the different software and they will not work. Why does it fail when php is installed properly but I only get errors about Sockets not working in the logs? What is a PGA? At the moment, cgminer supports 4 FPGAs: Since the acronym needs to be only 3 characters, the "Field-" part has been skipped.

There are more ADL devices than OpenCL. ADL devices include any ATI GPUs, including ones that can't mine, like some older R4xxx cards. To cope with this, the ADVANCED option for --gpu-map is provided with cgminer. DO NOT USE THIS UNLESS YOU KNOW WHAT YOU ARE DOING. The default will work the vast. You can use Pooler's CPU miner (right side, download zip link), also known as Minerd. You may need to install Visual C++ on your system. It is easy to find and download, does not use OpenCL (programming extension for graphics cards).
