Default Support of multiple core 64 bit processors and 4GB RAM

Just wondering if there is image processing software which can make full
use of 64 bit processors with more than one core (i.e. Core 2 Duo, Core
2 Quad or equivalents from AMD) and which can use more than 4GB RAM (I
know for instance of mainboards which take 8GB RAM)? Intel is planning
to have a processor with 32 cores by 2009.

The OS is the limit.
32bit Windows does not see all the 4gb of RAM.
Although 64bit Windows technically can see all that RAM it has problems with
stability, program and driver compatibility. Win64 will run Photoshop but
many if not most users cannot use that much RAM effectively.
Vista64 will not be any different, at least at outset, than Win64 and
probably have even less driver support for things like printers, scanners
and calibrators. In fact there will be inadequate driver support when Vista
32 is released in a few weeks.
The truth is that users may think they need that much RAM but the reality is
somewhat different despite what some computer enthusiast magazines/web sites
tout.

You'd need large amounts of RAM when processing large image files, for
instance scans of MF or LF negatives or pnoramic stitches.

I believe that Adobe PhotoShop uses the facilities of the 64 bit
processors. Whether or not a program uses the dual core machines to
full advantage depends on both the architecture of the program, and the
setting, and design, of the compiler. Using multiple processors is not
a simple thing, and even if the program is compiled for optimal
multi-processor use, the OS must also support it well in order for
maximum benefit to be derived. For any given program design, there is a
point of diminishing returns when it comes to adding processors. At
some point, no further advantage in speed will be noted.

The RAM issue depends on board design, and OS limitations.

First you need an OS that can handle 64 bits. Windows XP, for example is 32
bit and can read 4GB of ram in which 2GB is given to the OS and 2GB is given
to the apps. There is a startup switch to give 1GB to the OS and 3GB to the
apps, however the max RAM per app (per session) is still limited to 2GB. The
64 bit versions, of course, are not limited this way, but you need a 64 bit
app (like you asked about). I'm not sure if PS is truly 64 bit.

You must have a lot of images open or do a lot of stitching of many smaller
files to need such a large amount of RAM.

Don't know about 32 cores! Quad cores are just getting started and they will
likely run for the next couple years. 32 cores may be used for mini and
super computing uses. I don't see it in the desktop market for many more
years.

No, it won't be until after CSIII. Lots of engineering/development
issues around this, and the "improvement" would be marginal, according
to some experts. I'd be among them, but for the fact that I'm not an
expert in that field.

There are some who've read the hype of the chip mfgs. who believe that
64 bits *NOW* is a panacea.

It ain't.

Actually image processing is one task which can easily be parallelised -
just split the image into parts and assign each part to one processor.
Or, if you are doing panoramics, assign one image of the set to each
processor.

The problem is that with typical panoramas even 2GB are sometimes not
enough, and the computer starts disk swapping.
For instance, with PTGUI a panorama with the layered output option with
ten 10MP images generates easily a 300MByte file. Open that in your
image processing software, with multiple undo levels and you quickly end
up filling up several GB of RAM

Sorry, but isn't an advantage of 64 bit processors, that they can
address more than 4GB of RAM, which should help with memory hungry
situations?

As for multiple cores, they should help with image processing, an
application which can easily be parallelised.

The dual core G5 could- can address 8GB of Ram.
