AMD Forces a LibreOffice Speed Boost With GPU Acceleration
New submitter samtuke writes: AMD processors get rated and reviewed based on performance. It is in our self-interest to make things work really, really fast on AMD hardware. AMD engineers contribute to LibreOffice, for good reason. Think about what happens behind a spreadsheet calculation. There can be a huge amount of math. Writing software to take advantage of a Graphics Processing Unit (GPU) for general purpose computing is non-trivial. We know how to do it. AMD engineers wrote OpenCL kernels, and contributed them to the open source code base. Turning on the OpenCL option to enable GPU Compute resulted in a 500X+ speedup, about ¼ second vs. 2minutes, 21 seconds. Those measurements specifically come from the ground-water use sample from this set of Libre Office spreadsheets.
It can be. Don't generalize to use cases you don't know, especially when people with no real programming skills are concerned. I honestly don't know any other software that is both as flexible and accessible as spreadsheets when it comes to doing computations on heaps of (mostly irregular) data.
People use the tools they are familiar with. There are plenty of business types who are goddamn magic wizards with a spreadsheet who completely freeze up at the thought of putting a database together. I've seen spreadsheets clicking over into the 3-400mb range that have been used for years in organizations and you know it could be managed much more efficiently, yet people resist because it's easier for them to make quick modifications than passing along requests to a database admin.
"A GPU is not 500 times faster than a CPU, more like 2 or 3 times"
Just on FLOPs alone you're dead wrong. The latest and greatest E-series Xeons (V3) have barely enough power to match the 9800GTX+ - about 800 GigaFLOPs. The 980 GTX Ti is roughly 5.6 TeraFLOPs.
Still waiting on Serviscope_minor to wake up to fucking reality and realize that Jessica Price isn't going to fuck him.
...Just in the last week, I have seen spreadsheets used for a program logic workflow, a timetable, a university course schedule, to compute an FFT, to exchange student marks, to discuss a budget (with lots of deletions and remarks), and even for a presentation. In each and every case a more suitable, open-source, freely available, multi-platform application exists.
You've just stated the reason people use spreadsheets right there. One multi-purpose program vs umpteen specialist programs, each with their own UI quirks that have to be learned to make the most use of the programs. Why bother when a good old spreadsheet will work.
