Yes, there was a 64 bit version of Linux running on the DEC Alpha,
followed shortly by the IBM PowerPC around 1994 - 1995.

The 64-bit R4000 by MIPS technologies came out in 1992 and was first 
used in Silicon Graphics machines, running IRIX the SGI flavour of UNIX. 
This processor was 64-bit internally but 32-bit externally so only a 
32-bit wide memory-path could be used.Later versions, notably the R8000 
(1994) and the R1000 (1996) were 64-bit internally and externally. In 
1994 SGI licensed the memory architecture, developed by Cray (which it 
bought a few years later) and licensed it, I thought in  2002 to AMD for 
its 64-bit processors. This NUMA architecture is much faster than the 
standard architecture used in other processors and is much more suitable 
for multiprocessor systems.

With PAE, the 32 bit CPU can access more that 4 GB, but Microsoft still 
limits Windows to 4 GB.  With Linux, no there is no such artificial 
limitation.  IIRC, applications are still limited to 4 GB, as they don't 
know how to access more, but the OS can use the greater space and make 
it available to the apps.  With Linux, recently used stuff is retained 
in memory, so that accessing it again is quick.  It will eventually be 
moved to swap, if not recently used.  So, with Linux, the more memory 
available, including beyond 4 GB, the faster the system in general runs.

CPU Cycles is the process the processor takes to complete a command.
Multiple cores came about due to the current CPU overheating above 4GHZ .
So they started adding more cores to the existing processors to give you
more cpu threads to process commands. So in theory you can have a 3GHZ CPU
with dual cores (2 central processing units) to get the result of a 6ghz
processor.

You are correct, the 4GB limit was imposed by the operating system . 64bit
has been around for years, I believe someone else mention this on the
thread, its not new and unix/linux has been using it.


"If you imagine wires or cables as lanes on a motorway then double the
number of lanes can carry double the number of cars.  It's just that you
don't always need to have that many cars on a section of motorway.  "

Hi :)  

Are Cpu cycles to do with multi-core/multi-cpu?  If so it's presumably possible 
for 32bit apps to take advantage.  I think it's just a fluke that most of us 
think that 64bit machines tend to have more than 1 cpu/core and 32bit ones 
don't.  Both technologies became well known around the same time.  


Apparently the 4Gb Ram limit is a limit of the OS, not the apps.  If the OS can 
read/write to more ram then i don't think the apps would be restricted.  
Apparently OSes that are 32bit could read more Ram with a different kernel 
module.  With Gnu&Linux it's possible to swap-in the different module and i 
kept being  told that "it's really easy".  Something like the pae-something 
module.  


Ram is used more efficiently by OpenSource programs, especially when using 
quite a few at the same time.  My whole system is OpenSource apart from a few 
fonts and a couple of codecs and i seldom need even 1Gb.  Movies and even 
fairly hefty games seem quite happy.  I figure that if bits of my ram detiorate 
over time then i could always swap the sticks around to use the ones that 
aren't getting used at the moment.  

If it feels like LO/OO are bumping into ram issues then it's more likely to be 
the limits you set (or the default ones) in

Tools - Options - Memory


If you imagine wires or cables as lanes on a motorway then double the number of 
lanes can carry double the number of cars.  It's just that you don't always 
need to have that many cars on a section of motorway.

Tom :)

Since Libreoffice is a Office product . I don't believe you will see a big
differential in performance as a user . From a programmer view , you can
take advantage of the cpu cycles and memory usage with a 64bit system.

Most of the system on the market are 64bit . since 32bit can run in a
64bit environment I dont see the rush to change the application code to run
under 64bit. keep in mind i am not saying Libreoffice should not or will
not.


there is a high amount of user running Libreoffice under Windows.

 May I ask why our devs should work on a win64 version while we are having still a "few" bugs in 
the 3.6 branch (and also in 3.5.7).


How many LibO user are having wn64 machines? Or better what is the percentage of win64 users in the 
LibO community?
