OpenCL™ é o primeiro padrão aberto e isento de royalties destinado a programação paralela em processadores modernos nos computadores pessoais, servidores e dispositivos móveis. OpenCL (Open Computing Language) melhora significativamente a velocidade e a resposta de um amplo leque de aplicações em vários segmentos, desde jogos e programas de entretenimento até programas científicos e médicos.

By default, OpenCL is enabled in LibreOffice . While enabled, OpenCL takes advantage of a device’s GPU (graphics processing unit) for faster performance time during calculations. This is helpful when working with large spreadsheets in LibreOffice Calc that require calculations on large sets of data.

## OpenCL Options

If OpenCL is already enabled, the dialog displays OpenCL is available for use. If OpenCL is not currently enabled, the displays OpenCL is not used.

### Allow Use of OpenCL

Select or deselect this checkbox to enable or disable OpenCL. Select Apply or OK to update settings. In order for any changes to take effect, LibreOffice must be restarted.

OpenCL depends on the availability of working drivers for your computer hardware. If OpenCL is not enabled by default, the drivers are not in working state, they may not exist or they are not installed.
