The clCreateContext API is used to create a context that contains a Xilinx device that will communicate with the host machine.

context = clCreateContext(0, 1, &device_id, NULL, NULL, &err);

In the code example, the clCreateContext API is used to create a context that contains one Xilinx device. Xilinx recommends creating only one context per device or sub-device. However, the host program should use multiple contexts if sub-devices are used with one context for each sub-device.
