Returns the size of the buffer in bytes.

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

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

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

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

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.

Returns the context for the command queue.

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

Returns the context for the image sampler object.

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.

For CPU devices on Apple platform local memory can not be used when work group size is not [1;1;1]. If work group size is greater "Invalid Work Group

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

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 the context for the kernel.

where to put merged sequence

Enqueues a kernel for execution. \see_opencl_ref{clEnqueueNDRangeKernel}

Resizes the vector to \p size.

Returns the ID of the device.

Enqueues a command to map \p svm_ptr to the host memory space. \opencl_version_warning{2,0} \see_opencl2_ref{clEnqueueSVMMap}

Enqueues a command to unmap \p svm_ptr from the host memory space. \opencl_version_warning{2,0} \see_opencl2_ref{clEnqueueSVMUnmap}

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

Returns the width of the image.

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

Returns \c true if the device OpenCL version is major.minor or newer; otherwise returns \c false.

\internal_

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

Returns the number of compute units in the device.

Returns the format for the image.
