Basic Concepts: Writing OpenCL code for single and double precision
Support for double precision floating-point type double in OpenCL kernels requires an extension. AMD provides cl_khr_fp64 for newer high-edn hardware, but also a non-fully compliant cl_amd_fp64 extension for other hardware. NVIDIA and Intel support the cl_khr_fp64, so no exceptions need to…
Basic Concepts: out of resources with clEnqueueReadBuffer
In the series “Basic Concepts” various basics of GPGPU and OpenCL are discussed. This time we go into a typical one: when an error does not imply the actual problem. It is therefore good to have an overview of all errors…
