Traditionally, LibreOffice has had an appallingly slow and mis-architected spreadsheet core. Come and hear how we've re-designed it to take advantage of the major wins possible with both GPU and CPU parallelism, and extrapolate that to your application. See how Calc can now give you a real appreciation of what a teraflop of GPU computing power can really do inside your workstation, and understand how terrible things used to be.

Hear about the structural challenges that OpenCL and the GPU

brings, and how getting the underlying data structures and design right is the key to better performance. Grasp how the next generation of integrated CPU/GPU hardware with a Heterogenous System Architecture starts to enable efficient crunching of huge data-sets.

We'll also look at how we're starting to use threading to

speed up load/save not just in calc, but also in other parts of the suite. I'll also showcase some of the latest improvements in our FOSDEM release: LibreOffice 4.2.
