alethone-gui-rc2

The C++ implementation of the Ethereum client (cpp-ethereum) is getting more user friendly with the new AlethOne GUI intended to simplify the mining process for users that are not into programming and hate to use console-based software. The AlethOne GUI is going to be a part of the eth client, though currently it is only available in a release candidate form and it will be interfacing with the eth client. The first time you run the GUI it will ask you for a password and will generate an Ethereum wallet address, then start synchronizing the blockchain. The good thing is that AlethOne presents the user with a simple interface and reports in an easy to read details about the functionality of the eth client in the backend such as the Ether balance you have or the blockchain synchronization status or even the hashrate when mining. As for the mining you get an easy option for solo mining or pool mining with a field to enter the pool URL to mine at and after you have mined some coins you have the option to easily initiate a transfer to another account.

So far the latest release candidate of AlethOne looks quite nice and works decently, though there are apparently some more things that need work before the final release is available. For example it seems that the mining is only working on the first GPU and if you have multiple video cards that you want to mine with there is no way to tell the miner to use them all form the GUI apparently. The Withdraw functionality also needs some more work in te form of any feedback returned in the AlethOne GUI regarding the execution of the transaction such as if it was successful or not etc. Regardless things are already looking good and the AlethOne GUI with some more improvement and fixes is definitely something that Ethereum needs in order to become easier to be used by not so advanced users – basic wallet and mining functionality in a streamlined desktop client.

new-ethminer-cuda-updated

The developer of the Ethminer fork with Nvidia CUDA support (source) Genoil has released another update and we have compiled a new Windows binary of ethminer with CUDA support. Do note that this Windows binary release is compiled with VS2013 for windows 64-bit and is for CUDA 6.5. The latest version comes with some optimizations and a new command line option cuda-schedule to experiment with that replaces the old cuda-turbo, also note that you may need to manually specify the number of GPUs to use if you have multiple video cards using the cuda-devices command line parameter if the miner fires only on one device by default. Additionally to get better performance you can try adding the following command line parameters to the ethminer:

For OpenCL: --cl-global-work 16384
For CUDA: --cuda-grid-size 8192 --cuda-block-size 128 --cuda-schedule auto

--cuda-schedule Set the schedule mode for CUDA threads waiting for CUDA devices to finish work. Default is sync. Possible values for mode are:
auto – Uses a heuristic based on the number of active CUDA contexts in the process C and the number of logical processors in the system P. If C > P, then yield else spin.
spin – Instruct CUDA to actively spin when waiting for results from the device.
yield – Instruct CUDA to yield its thread when waiting for results from the device.
sync – Instruct CUDA to block the CPU thread on a synchronization primitive when waiting for the results from the device.

It seems that the auto mode for cuda-schedule works best for us providing maybe a bit lower maximum hashrate, but a more stable one than the sync that may produce higher maxes, but also lower. You are free to experiment what will work best on your mining configuration however. The Ethminer CUDA fork should work on Compute 2.0 or newer GPUs, but the performance on older GPUs can be worse, also don’t forget that you can run Ethminer in OpenCL mode as well on Nvidia-based video cards and not only on AMD if you are having trouble with the CUDA support or the hashrate you get is lower as compared to OpenCL.

ethminer-0-9-41-cuda-new

Genoil, the developer of the Ethminer fork with Nvidia CUDA support (source) has been actively working and there have been some other people contributing code, so we have compiled an up to date Windows binary of ethminer with CUDA support. Do note that this Windows binary release is compiled with VS2013 for Windows 64-bit and is for CUDA 6.5 as previous versions were compiled for CUDA 7.5, so there could be some performance differences between the different versions. The latest version comes with some optimizations that should increase a bit the performance when using the CUDA mode with the miner, however there are also some differences as you may need to manually specify the number of GPUs to use if you have multiple cards using the cuda-devices command line parameter if the miner fires only on one device. Additionally to get better performance you can try adding the following command line parameters to the ethminer:

For OpenCL: --cl-global-work 16384
For CUDA: --cuda-grid-size 8192 --cuda-block-size 128 --cuda-turbo

The Ethminer CUDA fork should work on Compute 2.0 or newer GPUs, but the performance on older GPUs can be worse, also don’t forget that you can run Ethminer in OpenCL mode as well on Nvidia-based video cards and not only on AMD if you are having trouble with the CUDA support or the hashrate you get is lower as compared to OpenCL.
