mmap-go
=======
mmap-go is a portable mmap package for the [Go programming language](http://golang.org).
It has been tested on Linux (386, amd64), OS X, and Windows (386). It should also
work on other Unix-like platforms, but hasn't been tested with them. I'm interested
to hear about the results.
I haven't been able to add more features without adding significant complexity,
so mmap-go doesn't support mprotect, mincore, and maybe a few other things.
If you're running on a Unix-like platform and need some of these features,
I suggest Gustavo Niemeyer's [gommap](http://labix.org/gommap).

# Ethash
For details on this project, please see the Ethereum wiki:
https://github.com/ethereum/wiki/wiki/Ethash
### Coding Style for C++ code:
Follow the same exact style as in [cpp-ethereum](https://github.com/ethereum/cpp-ethereum/blob/develop/CodingStandards.txt)
### Coding Style for C code:
The main thing above all is code consistency.
- Tabs for indentation. A tab is 4 spaces
- Try to stick to the [K&R](http://en.wikipedia.org/wiki/Indent_style#K.26R_style),
especially for the C code.
- Keep the line lengths reasonable. No hard limit on 80 characters but don't go further
than 110. Some people work with multiple buffers next to each other.
Make them like you :)

/*
This code have two main entry points:
1. The initCL(...) function configures one or more OpenCL device
(for now only GPU) and loads the Ethash DAG onto device memory
2. The Search(...) function loads a Ethash nonce into device(s) memory and
executes the Ethash OpenCL kernel.
Throughout the code, we refer to "host memory" and "device memory".
For most systems (e.g. regular PC GPU miner) the host memory is RAM and
device memory is the GPU global memory (e.g. GDDR5).

<h3>How does this work?</h3>
<p>This Ether faucet is running on the {{.Network}} network.

<p>To request funds, simply create a <a href="https://gist.github.com/" target="_about:blank">GitHub Gist</a> with your Ethereum address pasted into the contents (the file name doesn't matter), copy paste the gists URL into the above input box and fire away!
