OpenCL support has been added to LibreOffice Calc to greatly accelerate spreadsheet calculations! Now application users can experience GPU acceleration without programming. LibreOffice is a free and open source office suite developed by The Document Foundation. It contains popular office applications such as Writer (a word processor), Calc (for spreadsheets), Impress (for presentations), Draw (a vector graphics editor), Math (for mathematical notation), Base (a database) and more. LibreOffice runs on popular operating systems such as Linux, Windows, and OSX and common file formats such as those used in Microsoft Office.
It will be interesting to see both the adoption of OpenCL acceleration (although one must currently turn it on as it is off by default) and performance comparisons between the major vendors.
The following video shows the potential for fast spreadsheets due to GPU acceleration. (Unfortunately, the Intel GPU tested is not a high-end one like the Iris 5200.)
