Performace question

ROOT
1

With root 3.10.02 i reached 270 rootmarks on a p4 2.66 ghz 512 mb compiled on mandrake 9.2 . With the root 3.10.02 gdk for windows i reached 259 rootmarks on celeron 2.3 ghz 512 mb. is this consistent with what benchmark.C told me that p4 2.4 ghz has 600 rootmarks? what is better : higher rootmarks or lower :slight_smile: ?

Hi adrian_sev,
very strange. Could you send printout of benchmarks.C?

Regards. Valeriy

root 3.10.02 win gdk on Celeron 2.3 Ghz 512 mb ram
chipset i845 video onboard (could rootmarks depend of video performance? And also can be done a benchmark for batch mode (txt only) . One can want to mesure only cpu(+ram) power .

Hi,
I’m just curious: is it laptop?
For example, for my laptop I lose ~ factor of 2 in
benchmarks.C when it works standalone from battery.

++ You have very suspisious result in na49 test (3 times slower).
This test is not graphical one, only calculations and file I/O.

Regards. Valeriy

+++
Of cause benchmarks.C depends on video performance.
For example, using 16bit colors gives ~20% gain against 32bit colors

5

Yes it is laptop but wasnt on battery. I know i lose performance on battery becouse o throttle reduction but was on AC.
and you said :

<++ You have very suspisious result in na49 test (3 times slower).
<This test is not graphical one, only calculations and file I/O.
**************
(i seen same pads with na49 drawings (which is 3d geo so i guess OpenGL)

<Of cause benchmarks.C depends on video performance. <!!!>
<For example, using 16bit colors gives ~20% gain against 32bit colors

So whats gone be ? depends on graphical or not?
In this moment it is clear to me that root performance depends on graphical sistem. (of course depending of program used)
Can benchmark.C make graphical files on hdd instead draw them?
I think it be useful some benchemark that not depend of video system.

Hi,
there are another benchmarks tests.
Go to $ROOTSYS/test and type “make”
or you can build it with VC7 project (Makefile.sln)
located in the attachment (you will need to define ROOTSYS
enviroment variable via ControlPanel)

Run bench or stress tests.

Regards. Valeriy

++
send me results from these tests

i forgot : it seems that root win version is faster than linux compiled version (~ 30 rootmarks ) !!! :open_mouth: :open_mouth: :open_mouth: :open_mouth: :open_mouth:

Hi adrian_sev,
I suspect that your computer is not 2.3 Ghz
but around 1.3 Ghz :wink: . Make sure that I’m wrong.

That reminds me one “true story”. At early days
of IHEP one of the “gurus” looking at osciloscope gave
correct diagnoze : “there is lead-brick in the accelerator tube”

the BIOS tell me that is an Celeron at 2.3 Ghz .the same with sisoft sandra
and other tools

Hi adrian_sev,
did you try
downloadfinder.intel.com/scripts … ame=fidrus
In 5 min you will know about:

Expected Frequency:
This is the frequency at which Intel intended the processor
and the system bus to run.
This should be the speed physically marked on the processor’s packaging.

Reported Frequency:
This is the actual operating frequency
of the processor and system bus as measured by the utility.

Overclocked:
Processors or system bus that run
above their expected frequencies are considered to be overclocked.
Overclocked processors or system bus can produce unpredictable
results or system instabilities, which might not be readily apparent.
The life of the processor may also be shortened

Regards. Valeriy

Sorry i forgot to tell you that fidrus crashed my Windows Xp (whis is updated with all patches . ( second : is there fiden :smiley: ???
