OpenCL options
OpenCL (Open Computing Language) is a software architecture used to write programs that run in
different processors of the computer, such as the CPU and GPU (graphics processing unit) of the
video card. With OpenCL enabled, LibreOffice can benefit from the very fast numerical calculations
performed in the GPU, which is especially useful in very large spreadsheets with extensive
calculations. The computer video card driver must have support for OpenCL to use this feature.
OpenCL Options - Allow use of Software Interpreter (even when OpenCL is not available)
Mark this box to emulate OpenCL if your computer video card driver does not support
OpenCL.
Allow use of OpenCL
Let LibreOffice use the video card GPU to perform numerical calculation with great speed
gain. The two boxes below list the OpenCL drivers whitelist and blacklist. Click the Edit,
Add... and Delete buttons to modify the lists entries.
