/*
Package cl provides a binding to the OpenCL api. It's mostly a low-level
wrapper that avoids adding functionality while still making the interface
a little more friendly and easy to use.
Resource life-cycle management:
For any CL object that gets created (buffer, queue, kernel, etc..) you should
call object.Release() when finished with it to free the CL resources. This
explicitely calls the related clXXXRelease method for the type. However,
as a fallback there is a finalizer set for every resource item that takes
care of it (eventually) if Release isn't called. In this way you can have
better control over the life cycle of resources while having a fall back
to avoid leaks. This is similar to how file handles and such are handled
in the Go standard packages.

*
* The pitch specified must be a multiple of CL_DEVICE_IMAGE_PITCH_ALIGNMENT pixels.
* The base address of the buffer must be aligned to CL_DEVICE_IMAGE_BASE_ADDRESS_ALIGNMENT pixels.

* Vector types

* Note: OpenCL requires that all types be naturally aligned.
* This means that vector types must be naturally aligned.
* For example, a vector of four floats must be aligned to
* a 16 byte boundary (calculated as 4 * the natural 4-byte
* alignment of the float). The alignment qualifiers here
* will only function properly if your compiler supports them
* and if you don't actively work to defeat them. For example,
* in order for a cl_float4 to be 16 byte aligned in a struct,
* the start of the struct must itself be 16-byte aligned.
*
* Maintaining proper alignment is the user's responsibility.

* const char *my_program = CL_PROGRAM_STRING_DEBUG_INFO "\

/*
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).
