There are no specific recommendations on how to implement the host code.
The user should consider this in accordance with the OpenCL™ Standard.

Although it is not an implementation method, regarding performance improvement using OpenCL, there is a guideline document for improving the performance of the core kernel program.
　

• Check the kernel bottleneck with reference to the profiler
• 1 work item/kernel performance improvement technique
• NDRange/Processing Data Efficiency Improvement Method
• Memory Access Efficiency Improvement Method
• FPGA Utilization Optimization Techniques
