Ethereum cpu mining calculator
From these numbers I assume the Go implementation is single threaded I don't know the language well enough to be sure. Can someone familiar with the GO implementation confirm about the CPU mining being currently single threaded or not? Using my modified Ethash benchmark for multithread tests shows a hashrate increase to be a bit less than a multiple of the number of hardware cores as expected. The setup is a dual socket Xeon E v2 2.
To me, this is further confirming that CPU mining will not be economically competitive compare to GPU mining rigs as intended by the design. I'm still not seeing any arguments in there to access GPUs installed on the machine.
This may be too much to ask but is there someone who can take an educated guess at the setup to purchase to mine Ethereum today and what might benefits there might be for a GPU mining solution in the future?
I am willing to pay a. How much better is it to mine with Ubuntu vs Windows 2. If I have 2MB up and 20MB download connection speed does it make sense to pay an extra 10 dollars a month to get more bandwith to be able to mine more? Can you give me three side by side comparisons of two medium costs systems and one expensive system? There is no difference 2. Your connection is just fine 3. You basically just need a normal computer, you don't need a top of the line cpu or ram or hdd.
If you plan on running more than one gpu, you will need a motherboard that can handle that and usb riser cards. Your expense is going to come down to which gpus you want to run and how many and then that will determine which power supplies you need, which are going to be expensive as well.
If you are going to run multiple cards there are going to be other expenses as well, structure to hold all the parts I just use adjustable shelves from Home Depot , how to get all that power to the cards, cooling etc. That's probably conservative too. They could be on equal playing ground depending on how dagger hashimoto turns out. Genoil 0xebbffdab3dfb4d Member Posts: April edited April This is because the full Dagger dataset is loaded onto the GPU.
For now that's 1GB, but it will eventually grow to more GB than current cards have. Thanks for the info Genoil! Which client did you use for mining with that AMD card? I'd like to see what my hashrate is too! Yep the cpp OpenCL benchmark on Win That's really low compared to what MarioFortier is reporting. Genoil , thanks for sharing benchmarking information.
Any node participating in the network can be a miner and their expected revenue from mining will be directly proportional to their relative mining power or hashrate , i. Memory hardness is achieved with a proof of work algorithm that requires choosing subsets of a fixed resource dependent on the nonce and block header.
This resource a few gigabyte size data is called a DAG. The DAG is totally different every blocks, a hour window called epoch roughly 5. Since the DAG only depends on block height, it can be pregenerated but if its not, the client needs to wait until the end of this process to produce a block. If clients do not pregenerate and cache DAGs ahead of time the network may experience massive block delay on each epoch transition.
As a special case, when you start up your node from scratch, mining will only start once the DAG is built for the current epoch. All the gas consumed by the execution of all the transactions in the block submitted by the winning miner is paid by the senders of each transaction. Over time, it is expected these will dwarf the static block reward. Uncles are stale blocks i.
Valid uncles are rewarded in order to neutralise the effect of network lag on the dispersion of mining rewards, thereby increasing security this is called the GHOST protocol. A maximum of 2 uncles are allowed per block. Mining success depends on the set block difficulty. Block difficulty dynamically adjusts each block in order to regulate the network hashing power to produce a 12 second blocktime.
Your chances of finding a block therefore follows from your hashrate relative to difficulty. Ethash uses a DAG directed acyclic graph for the proof of work algorithm, this is generated for each epoch , i. The DAG takes a long time to generate. If clients only generate it on demand, you may see a long wait at each epoch transition before the first block of the new epoch is found.
However, the DAG only depends on the block number, so it can and should be calculated in advance to avoid long wait times at each epoch transition. Both geth and ethminer implement automatic DAG generation and maintains two DAGs at a time for smooth epoch transitions.
Automatic DAG generation is turned on and off when mining is controlled from the console. It is also turned on by default if geth is launched with the --mine option. Note that clients share a DAG resource, so if you are running multiple instances of any client, make sure automatic dag generation is switched off in all but one instance. It is designed to hash a fast verifiability time within a slow CPU-only environment, yet provide vast speed-ups for mining when provided with a large amount of memory with high-bandwidth.
The large memory requirements mean that large-scale miners get comparatively little super-linear benefit. The high bandwidth requirement means that a speed-up from piling on many super-fast processing units sharing the same memory gives little benefit over a single unit. This is important in that pool mining have no benefit for nodes doing verification, thus discourageing centralisation. In order to mine you need a fully synced Ethereum client that is enabled for mining and at least one ethereum account.
This account is used to send the mining rewards to and is often referred to as coinbase or etherbase. Ensure your blockchain is fully synchronised with the main chain before starting to mine, otherwise you will not be mining on the main chain. This is no longer profitable, since GPU miners are roughly two orders of magnitude more efficient. However, you can use CPU mining to mine on the Morden testnet or a private chain for the purposes of creating the ether you need to test contracts and transactions without spending your real ether on the live network.
The testnet ether has no value other than using it for testing purposes see Test Networks. When you start up your ethereum node with geth it is not mining by default.
To start it in CPU mining mode, you use the --mine command line option. The -minerthreads parameter can be used to set the number parallel mining threads defaulting to the total number of processor cores. You can also start and stop CPU mining at runtime using the console. Note that mining for real ether only makes sense if you are in sync with the network since you mine on top of the consensus block.
In order to earn ether you must have your etherbase or coinbase address set. This etherbase defaults to your primary account. Note that your etherbase does not need to be an address of a local account, just an existing one. There is an option to add extra Data 32 bytes only to your mined blocks.
By convention this is interpreted as a unicode string, so you can set your short vanity tag. You can check your hashrate with miner.
After you successfully mined some blocks, you can check the ether balance of your etherbase account. Now assuming your etherbase is a local account:. You can check which blocks are mined by a particular miner address with the following code snippet on the console:.
Note that it will happen often that you find a block yet it never makes it to the canonical chain. This means when you locally include your mined block, the current state will show the mining reward credited to your account, however, after a while, the better chain is discovered and we switch to a chain in which your block is not included and therefore no mining reward is credited. Therefore it is quite possible that as a miner monitoring their coinbase balance will find that it may fluctuate quite a bit.
If you get Error GPU mining. To get openCL for your chipset and platform, try:. Unfortunately, for some of you this will not work due to a known bug in Ubuntu Whatever you do, if you are on You can change this by giving the --rpcport option to geth.
