fast::Queue class
#include <FAST/OpenCLProgram.hpp>

Wrapper for OpenCL CommandQueue.

Constructors, destructors, conversion operators

void add(const Kernel& kernel, std::vector<int> globalSize, std::vector<int> offset = std::vector<int>(), std::vector<int> groupSize = std::vector<int>()): Enqueue a Kernel to this command queue.
void finish(): Block until entire command queue is finished.
void addReadBuffer(OpenCLBuffer buffer, bool block, std::size_t offset, std::size_t size, void* pointerToData): Copy data from buffer on device to pointer on host.
void addWriteBuffer(OpenCLBuffer buffer, bool block, std::size_t offset, std::size_t size, void* pointerToData): Write data from host pointer to OpenCL buffer.
void addCopyBuffer(OpenCLBuffer srcBuffer, OpenCLBuffer dstBuffer, std::size_t srcOffset, std::size_t destOffset, std::size_t size): Copy data from one OpenCL buffer (source) to another (destination)
auto getHandle() const -> cl::CommandQueue

Enqueue a Kernel to this command queue.

Parameters
kernel
globalSize	total number of work-items for each dimension
offset	work-item offset, if none is given, it is zero for all dimensions
groupSize	How many work-items should be each work-group for each dimension. If not provided, platform will decide automatically

Copy data from buffer on device to pointer on host.

Parameters
buffer	OpenCL buffer to read from
block	Whether this call should block and wait until the data operation is finished.
offset	Byte offset in OpenCL buffer
size	nr of bytes to read (e.g. elements*sizeof(datatype))
pointerToData	Pointer to host memory to read data into. Must be allocated with big enough size

Write data from host pointer to OpenCL buffer.

Parameters
buffer	OpenCL buffer to write data to
block	Whether this call should block and wait until the data operation is finished.
offset	Byte offset in OpenCL buffer to write data to
size	nr of bytes to write (e.g. elements*sizeof(datatype))
pointerToData	Pointer to host memory to read data from. Must be bigger than size.

Copy data from one OpenCL buffer (source) to another (destination)

Parameters
srcBuffer	source OpenCL buffer
dstBuffer	destination OpenCL buffer
srcOffset	offset in bytes in source buffer
destOffset	offset in bytes in destination buffer
size	size in bytes (e.g. elements*sizeof(datatype))
