I saved all of the replys that I
received when I was thinking about getting a faster computer.
Dingo knows a lot about this subject. I have attached some of
the replies that I received at that time. I have saved more if anyone
wants to see them.
I finally realized that
I already owned the best computer of all. It is called a brain. It is
not that important how fast your brain runs. The former
American President, Calvin Coolidge gave the best instructions on how to
use your brain.
"Nothing in the world can take the
place of persistence. Talent will not; nothing is more common than
unsuccessful men with talent. Genius will not; unrewarded genius is almost
a proverb. Education will not; the world is full of educated
derelicts. PERSISTENCE AND DETERMINATION ARE
OMNIPOTENT".
Hope this helps. Ron

Subject: [amibroker] Off Topic: Optimizing
a PC for Amibroker Backtesting - What's most important?
I am looking at getting a PC
dedicated to running Amibroker backtests and was wondering if anyone had any
input on what the most important performance attributes would be.
I am thinking of an Intel Pentium
Extreme Edition or Athlon 64 FX-55. It seems the difference is that the Intel
has a bigger cache which seems like that could make a difference. Also TJ once
indicated that hard drive performance is important so one might think that a
RAID 0 with 2 WD 10,000 RPM drives might be the way to go if that is true.
Lastly, it’s not clear if memory beyond say 1GB would make much
difference.
Has anyone tried to come up with the
fastest backtesting PC or have any opinions on what attributes of the PC would
be most important. I suppose one could optimize everywhere but that could be
overkill.
Thanks for any
insights.

If all you're going to run is AB then 1 processor. If you'd
like to run other things at the same time then 2.
You didn't say what your budget is so if it is high then go
for the new AMD 64 bit machines.
I don't know specifically what ram you need but you can
find out easily enuf - it would have to work with the mother board you
choose. Make sure you get enuf memory so that AB can cache all of the
data it will need for the 7000 tickers plus the op system, etc (At least 1 gig).
That way you can minimize the times it has to hit your hard disk.
Here are some sites for you to surf:
Here
are some manufacturers of hot systems for you to compare what you plan to make
yourself against what's available from them:
You
can get your sources for the components you need from the first group of links
above.

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

Ron,
The last round of discussions on dual processors
the word was that, as youremeber, you will not benefit very much with
Amibroker.
Suggest you buy the fastest processor you can with
fast disk and 1GB memory.
Critical item: Make sure you have optimum
parameters in AA settings.

I meant to ask you how long your exploration is taking
now?
What expectations do you have on how long it would take on
a new machine?
You might compose a version of your exploration that you
can send out to voluteers on the board and ask them to run it for some
benchmarks. That way you can see what might be
realistic.

32 bit software will run "as is" on the Athlon 64 chip. However, it does
not benefit from the
increased capability of the chip. Basically runs the same as on a 32
bit chip. To really take
advantage 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 language
like Visual Basic, this is probably not feasible until Microsoft
releases a 64 bit version of
Visual 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 I
know 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 motherboard
increases 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.

Most 32 bit programs do require an extreme
rewrite to be able to truly make use of a 64 bit processor. They likely
shan't take the time or trouble. You then have to debug what
you've written.
I've put together a list of the parts that
I'm purchasing for myself this week for my new speed demon
machine.
Asus
ONLINE ORDER ONLY - - A7N8X-E XP 3200
Deluxe nVIDIA nForce2 400MHz FSB
DDR400 Serial ATA Dual LAN Firewire 1394 ATX.
Details:
-with cpu - Athlon XP 3200+ 2.2GHz 00MHz with Heatsink &
Fan. Complete
Combo kit
Price $ 346
1GB PC-3200 DDR400 RAM Dual Channel SPD Enhanced
PC3200 DDR 1GB In
Stock Free Heat Spreader
Price - $155
Xoxide LED Clear Blue UV Reactive Acrylic
Case
Price $129.99
500W Aspire Super UV Reactive Power Supply
(Blue)
Price $79.99
ATI All In Wonder Radeon 9000 64MB TV/Vivo Video
Capture/edit AIW w/all
Cables OEM
Price -
$139
Total; $851, not including shipping. Since
all these are coming from different distributers, there will be multiple
shipping costs. I shall look for another day or so to see if I can find
someplace where, even if the parts cost a little more, I can save the difference
on shipping.
Let me know if you want me to order you the same
stuff. This machine is cutting edge, fastest there is in 32 bit
processors. Especially where rapid refresh rates are a must for
graphics. It is possible that you might get faster number crunching from a
four gig Pentium, but not by much.

A while back, you all graciously offered advice on what to include when I make a new very fast computer.
Well, finally, I will be ordering the parts this month, and I am willing to spend over $2000 for the parts if each additional chunk of money adds a few percentage points to the speed.
I think I would like to use this new SCA 80 pin system in my new fast computer. This innovation, and others that help the speed are what I would like to have in the new fast computer that I need very soon. I would appreciate your alerting me to any and all features that I can include in the fast computer that I need to build.
Also, I would like to hear comments/criticism of the fast computer list of parts pasted directly under the dotted line below.
Directly below is the link to the New SCA 80-pin that I just now saw during a search. Ron D

Ron,
Get all your stuff through one distrib. It saves LOTS of hassels with
warranties.
Try to avoid motherboards with onboard video. (Even if your going to be
plugging in your own video card.)
Onboard sound is good nowdays - So go with that if you can.
And buy a Chipset heatsink kit and Heatsink ALL the big chips on the
motherboard.
(One of the most common failure/errors of motherboards is chipset overheating)

Hello,
I fully agree, especially considering the fact that NVidia drivers
have superior OpenGL implementation -> means no problems
with any resolution and any color depth in 3D optimization chart viewer.
I am mentioning this because some ATI cards/drivers required
lowering color depth to display 3D optimizaiton chart correctly,
while NVidia drivers have never shown any problem.
Best regards,
