An '''OpenCL miner''' is a bitcoin miner that uses the [http://en.wikipedia.org/wiki/OpenCL OpenCL framework] to perform the [[hash|hashing]] computations. When used with a modern GPU, this can produce hash rates orders of magnitude higher than what can be achieved with a CPU.

==Overview==

OpenCL is a computing framework which allows programmers to write code which works across a variety of hardware, both CPUs and GPUs included. OpenCL was originally developed by Apple.

The use of an OpenCL miner allows one to hash using a GPU (Graphics Processing Unit), which has a vastly larger ability to perform algorithmic calculations than an CPU (Central Processing Unit).

==Requirements==

Hashing on a GPU requires an OpenCL compatible ([http://developer.amd.com/gpu/AMDAPPSDK/pages/DriverCompatibility.aspx ATI/AMD]) or CUDA compatible ([http://www.nvidia.com/object/cuda_gpus.html NVIDIA]) graphics card.

The python [[Poclbm]] open source OpenCL bitcoin miner was created by m0mchil based on the open source CUDA client originally released by puddinpop.

Subsequently the java [[DiabloMiner]] based on m0mchil's was created by Diablo-D3.

Puddinpop has also released a C++ OpenCL client capable of being compiled into the GUI client or daemon, or as a stand alone RPC miner.

Another miner was released by Jedi95 & CFSworks released [[Phoenix miner]] which can work with memory underclocked to 300MHz and scans whole 2<sup>32</sup> nonce space.

BitTornado is another OpenCL Miner that supports ATI and NVIDIA Cards. It was released by Chris Evans.

See the [[Mining Hardware Comparison]] page for detailed statistics on the hash rates that can be achieved with various hardware.
