therefore take adavantage of the new design. BUT the AMD processor will run all
32 bit applications faster than any Intel or AMD 32 bit processor accoring to
everything I've read.

BUT remember when I suggested the 64 bitter I also said that if money were not
an issue. Only you can say for sure if it is worth the extra
money. I don't know what the metrics are regarding how fast AB will
run on the 64 vs the 32 but say it will run 15-20% faster.. Is that worth the
difference in cost to you?

Computer
Thanks for the comments, and for mentioning the 64
processors.. It obviously makes a lot of sense to pay more for a
64 processor if Amibroker will run faster on it.
Below, I have copied an email from a knowledgeable
local computer user regarding 64 processors. This email is from someone who
does not use Amibroker.
I am wondering if the latest version of Amibroker
run faster on 64 bit processors, or does it need to be recompiled with a new
64 bit compiler as mentioned in the below email? What about the apparent need
for a XP Pro to be 64 Processor friendly?
I have also included a link to a website that compares
the Intel and AMD 64 bit processors. Which of these do you think would
be the best for Amibroker right now, or perhaps the future when Amibroker
can benefit from use of a 64 processor.
If some of these questions amuse you, remember
that I have a low level of computer skills, and so I barely understand a
lot of this. I certainly don't understand most of the
discussion in this link. Later Ron D

64 processor comments are
below.
<FONT
face=Arial>===========================================================================
32 bit software will run "as is" on the Athlon 64 chip. However, it does
not benefit from theincreased capability of the chip. Basically runs
the same as on a 32 bit chip. To really takeadvantage of the 64 bit
chip the software must be re-compiled with a new 64 bit compiler.The is
could be trivial or it could be a real problem. If it is written in some
higher level languagelike Visual Basic, this is probably not feasible
until Microsoft releases a 64 bit version ofVisual Basic. Very
little software is available to work with the new 64 bit chips.
Adobe has a version of Photoshop and Microsoft has a version of XP. That
is about all Iknow of at this time. Therefore there is not much
reason to go to the 64 bit chips at the
high price they get now.
About multiprocessors - tests have shown that adding a second processor
to the motherboardincreases through put by about 30%. The third processor
about 15% and so on down.So a single processor 3 gig is probably
better than two 2 gig multiprocessors.The problem is access to system
resources must be restricted to one processor at a time.Symetrical
multi-processors has been a disapointment.

Tigerdirect.com has good pictures, usually. You
will find a BioStar SFF aluminum case and MB for the Athlon
64.
You can still install dual Raptor 10,000 rpm high speed
fast seek hard drives in RAID 0. Two RAM slots hold 2
G.
Instructions are good enough to finish assembling the
system an hour or so. Wiring very neat.
The MB contains dual monitor support, but has an AGP
port for a Matrox $60 dual digital monitor 2D AGP card.
Your one ISA port may not be needed, unless you wish to
have audiophile & stereophile quality music playing. The M-Audio Rev.
7.1 card is under $100 and the AEGO 2 speakers are highly recommended. <A

Check it out for power, style, convenience and

[amibroker] Faster Computer
I am going to custombuild a computer that is
equipped to run Amibroker explorations as fast as possible.
I am running explorations of a huge number of
moving averages on over 7000 stocks. These explorations
take a long time on my AMD1 GHz, 768 MB XP Pro
desktop.
I have several questions that
some of you may know the answers to, or at least have opinions
about.
#1 If I am running only an Amibroker
exploration, and no other programs, will a dual processor help none at
all, a
little, or a
lot. I think I heard that a program has to be written in a
certain way in order to be able to run
faster on a
dual processing machine.
#2 If a dual processor will help, then
which ones should I consider.
#3 Even If a dual processor will help, I
still want to stay with a single processor if it is at least 80% as
fast as a
dual processor
when Exploring in Amibroker. Which regular processors would you
recommend?
AMD #xxxxx, of
Intel #yyyy, or other #zzzzz.
#3 I also want to have a very fast
RAM. What kind, how much, etc.
TIA for your thoughts. Ron D
