Hi All,
I finished setting up the new quad-core machine and
ran my first tests today, so am posting the promised test results. All I
can say is Wow! Really nice improvements, even better than
I expected to see in my highest hopes. I am happy as a
pig in sh*t !! 8 - )
For background, the test was an optimization
run on a single ticker, which is how I will be running all my
other tests ( ticker was QID, 468 EOD data bars ). All tests used the
same code with different param settings, all tests had about 46,000 opt
steps.
To put things in perspective and show why I am so
happy, the original code was about 2,400 lines. The first time I ran it, on my
old backup computer which I was using as a dedicated optimization machine,
it took 7 1/2 hours to run. So then I copied the code and created a shorter
version, removing everything which wasn't absolutley necessary for the
optimizer, and that reduced the run time to 2 1/2 hours. Then I ran this
short version on my faster primary machine and that took 1 1/4 hours,
which is about what I was expecting to see on the new machine.
So today I started by running just
ran one instance on the quad-core - that took only 30 mins
and Task Manager showed it was using just 25% of the total processing
power! Well to make a long story short, I kept adding one instance at
a time, all instances ran in 30 mins and each used up an additional 25% of
the CPU power. In the end, I was easily running 4 simultaneous
instances. This pretty much kept the CPU tached at 100% but all instances ran
fine, all finished in 30 mins and I didn't experience any
problems at all. I was even saving the first ones to spreadsheets while the
final ones were still finishing, wow everything just worked flawlessly!
So, the quad-core can run 4 seperate opts simultaneously in 30 mins,
which averages out to 7 1/2 minutes per opt, which =
10X improvement over running the short code on the
fast machine...
20X improvement over running the short code on the
old dedicated optimization machine...
60X improvement over running the original code on
the old optimization machine... Awesome !!!
To those who were wondering what is the best
machine to get for running AB, it looks to me like quad is the way to
go. ( My machine has an Intel processor, which TJ mentioned should
probably work better than AMD for this stuff )....
