Linpack
Motorola Xoom gets overclocked and tested with Linpack

Saw this video via Android Police:
Check it out from the beginning, Linpack gets tested at about 40 seconds in.
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.
Nexus One with Froyo takes the Lead at 40.099 MFLOPS
Mar 15th
We’ve had two different Nexus One phones with four good Top 10 Linpack runs. The best being 40.099 MFLOPS! Looks like some Droids need to do some catching up. I’m fairly certain that these are not bogus runs, since I’ve added some anti-cheat mechanisms to the most recent release. Still some funny results do occur when you overclock.
So is it Google teasing us??
As cyanogen said via twitter “Linpack #4 is an N1 running Froyo. Cheaters”
And of course, TheDudesAndroid said “***shakes fist at userid****”
XDAndroid
Mar 12th
TMONEWS has a posting about XDAndroid and how it is much more stable on a HTC Touch Pro 2. As they state, “the Android installation experiences no difficulty in making calls, sending SMS, downloading apps, or browsing the web. In fact, pretty much everything works besides GPS, Bluetooth, and the camera. ”
XDAndroid is a project to port Android to Windows Mobile devices. This is being developed by the guys on the forums of xda-developers.
What I found interesting was that there were a couple Linpack postings for XDAndroid loaded devices. So, I added XDANDROID to the Device list. It will be interesting to see how well it performs on Windows Mobile devices.
Removed Jw52637 50.592 Run from TOP10
Mar 11th
Ok, sorry Jw52637. I decided to delist the 50.592 run from the Top10 list. I’ve received and seen lots of comments from people that the run was faked, that you hacked into the list or I just made it up. From what I can tell it was a legitimate Linpack run since I have a check for fake uploads. I also doubt the site was hacked to add it since it also had the right check value. About the only thing I can think, that it didn’t run correctly and thus had an incorrect MFLOP number. I say this since his runs the day before topped out at 9.269
So in the next version, I’m going to check for an invalid run so that it can’t get uploaded.
