Do you really think it makes sense that Calc and Base are not prepared to
use all the computing power available?

Why do you think TDF and AMD are trying to bring GPU calculation to LO?
Because Calc (I haven't even tried Base...) is absurdly slow!

A heavy calculation spreadsheet I have takes 50 "seconds" to open in Excel
2010 and takes more than 10 *minutes* to open in Calc! (both 32bit versions)

No wonder Kohei Yoshida (one of, if not *the* main Calc developer) said
recently (August 2013): " You can’t compare Calc with Excel yet. They are
still miles ahead of us."

When Calc is able to use all cores and threads and eventually 64bit
operations then it might be on par...

Why do you assume the OP isn't doing number crunching?

To be honest, number crunching on a GPU is better than a CPU, since GPUs
were designed to number crunch.  Look at the newer CUDA and ATI GPU
cards.  They have 32, 64, 128, 512, or more "cores" or "streams".  There
is a movement to create systems that are GPU based instead of CPU
based.  The gaming systems are almost all GPU based, since they do not
need to run traditional packages that a "home" or business computer
needs to work with.

Well, the Excel vs. Calc speed comparison on the same system [32-bit] is
a different "thing" than making a 64-bit version of LO or a GPU based LO
package.  The difference between Calc and Excel may be the efficiency of
the coding.  There are still a lot of old legacy code in LO that is
being worked on to make it work better and much more efficient.  Just
saying we need to create a 64-bit version of LO to fix the "speed
issues" is not really solving that issue.

As for making LO work with a GPU card, well I would not be surprised
that not too long from now, both Windows and Linux will have a version
that is GPU based.  That is one of the things that would make our
current systems faster without replacing the motherboard or CPU.  Just
buy a newer, faster, GPU for the system.  This is what the gamers do
currently.  The price of these faster GPUs are going down.  For $100, I
could buy a GPU 3 to 4 time faster than one I could buy 2 or 3 years
ago.  The GPU speeds per price is a much better "ratio" than the CPU
speed per price.  You just get more speed or number crunching power for
you money with a GPU card, compared to the CPU/motherboard costs.
