Returns the size of the buffer in bytes.

Returns the result of the computation. This will block until the result is ready.

Blocks until all outstanding computations on the default command queue are complete. This is equivalent to: \code system::default_queue().finish(); \

parses command line arguments and sets the corresponding perf variables

Returns the function name for the kernel.

Returns the device for the context. If the context contains multiple devices, the first is returned.

Inserts \p value at the end of the vector (resizing if neccessary). Note that calling \c push_back() to insert data values one at a time is inefficie

Convenience method which calls enqueue_nd_range_kernel() with a one-dimensional range.

Returns a cl_event pointer to the first event in the wait-list. Returns \c 0 if the wait-list is empty. This can be used to pass the wait-list to Ope

Returns the context for the image sampler object.

Sets the argument at \p index to \p value with \p size. \see_opencl_ref{clSetKernelArg}

Returns the context for the command queue.

Returns the context for the kernel.

Builds the program with \p options. If the program fails to compile, this function will throw an opencl_error exception. \code try { // attempt to co

Returns a pointer to the extents data array. This is useful for passing the extents data to OpenCL APIs which expect an array of \c size_t.

Enqueues a kernel to execute using a single work-item. \see_opencl_ref{clEnqueueTask}

\internal_ Returns a command queue usable to issue commands for the vector's memory buffer. This is used when a member function is called without spe

Enqueues a kernel for execution. \see_opencl_ref{clEnqueueNDRangeKernel}

Returns the ID of the device.

Returns the width of the image.

Returns the format for the image.

Returns the height of the image. For 1D images, this function will return \c 1.

Resizes the vector to \p size.

Returns \c true if the device supports the extension with \p name.

Blocks until the actions corresponding to the event have completed.

where to put merged sequence

Returns the underlying event object.

Returns the size (width, height) of the texture.

Returns the name of the vendor for the device.

Loads the program with \p key from the cache if it exists. Otherwise builds a new program with \p source and \p options, stores it in the cache, and r

Enqueues a command to write data from host memory to \p buffer. \see_opencl_ref{clEnqueueWriteBuffer} \see copy()

Enqueues a command to read data from \p buffer to host memory. \see_opencl_ref{clEnqueueReadBuffer} \see copy()
