5.4.5. Enabling the Intel® FPGA SDK for OpenCL™ Channels for OpenCL Kernel

To implement the Intel® FPGA SDK for OpenCL™ channels extension, modify your OpenCL kernels to include channels-specific pragma and API calls.

To enable the channel extension, use the following pragma:

#pragma OPENCL EXTENSION cl_intel_channels : enable

Channel declarations are unique within a given OpenCL kernel program. Also, channel instances are unique for every OpenCL kernel program device pair. If the runtime loads a single OpenCL kernel program onto multiple devices, each device will have a single copy of the channel. However, these channel copies are independent and do not share data across the devices.
