Froyo for Galaxy S Spotted here first
Aug 30th
If you had an eagle eye and watched the Latest Posts here for Linpack, you would have seen the GT-i9000 posted a Linpack score on 26 Aug. This was before it was announced a couple of days ago as being leaked and in the wild. See: http://www.samsunghub.com/2010/07/28/galaxy-s-i9000-android-2-2-build-leaked/
Now the score that day was 13.415, which not what I was hoping. I have a Vibrant and I would like to see a number like the Nexus One or Droid Incredible. It’s still better than the 8s that I have been getting.
I’m more interested in getting the GPS and compass fix first.
Also, if you looked at the smdkc110 (Samsung Development Kit), you’ll see that it is running a GT-I9000 ROM too. The best score there is 20.7, so hopefully they have some more tweaking to do.
KISS
Aug 10th
I try to follow the KISS principle… Keep It Simple Stupid.
I haven’t updated Linpack in a long time and I knew that I need to make some major changes. So, I updated the app this morning with the first major change in almost 4 months. I increased the matrix that is calculated from 200×200 to 500×500. This change was done to hopefully reduce the number of erroneous MFLOPS numbers. With the matrix at 200, times were starting to get well under 1 second. This is not good for a timing benchmark. Since FroYo is taking over, the matrix had to be
enlarged to make the calculation take longer. This happened with the Java Linpack in the 90s, with faster systems they had to increase the size of the matrix too.
Don’t be surprised if your Linpack run takes up to 6 times longer to run, it’s supposed to do that. Look at the resulting MFLOPS over several runs; hopefully they will be more consistent.
I also updated the Mhz value obtained to show the actual Mhz the system is running at the end of the Linpack run. And I included a new button for the Latest Runs. This shows the latest runs by everyone (slow or fast) over the last few days.
