LibreOffice Getting Better Multi-Threaded Goodness
Written by Michael Larabel in Free Software on 7 November 2013 at 01:50 AM EST. 12 Comments
LibreOffice has been exciting to talk about recently with the landing of GPU/OpenCL calculation support and an OpenGL canvas plus many other features forthcoming in LibreOffice 4.2. The latest work underway is on working out multi-threaded importing for Calc.

Kohei Yoshida at Collabora is working on improving the spread-sheet component of LibreOffice, Calc, with some multi-threaded support. Kohei is working on allowing formula cell compilations to occur in multiple threads during XLSX file importing. When opening the Microsoft Excel OpenXML Spreadsheets, the goal is to utilize one CPU thread per sheet.

The initial support for multi-threaded XLSX importing was committed to Git yesterday, but it's still stuck being single-threaded until Calc core and other code has been made more multi-threaded friendly in dealing with reentrancy.

Let's hope more of LibreOffice will become OpenCL and multi-threading friendly in due time.
