Friendly little Linpack War

Taking a few days off from here because of my “real” job was hitting the fan.  I see that we have a Linpack War going on.  If you look at the Top 10 list and the Nexus One device list you’ll see lots of movement.  AndroidSpin has done a nice job of covering all the bases on the reasons behind the friendly competition. 
“Originally this was just a “friendly” little bet between WootRoot and TheDudesAndroid that a 2.0GHz kernel would or wouldn’t work on the Nexus One. Somehow WootRoot convinced Kmobs to build the kernel (I have a feeling Chris Soyars also played a part in that) and WootRoot bet TheDudesAndroid $50 that he could boot his Nexus, send a tweet and play a video before his phone melted.

WootRoot tried. It didn’t work. But it also didn’t melt. Kmobs got curious and toyed around with frequencies and voltages and they went from 1.113GHz (which was supposed to be the stable max) to 1.267GHz. Of course, it wasn’t until Acsteffy87 decided to run the kernel on his Nexus as well, that TheDudesAndroid found his “courage” and booted it on his too. (I think I’m going to be in trouble for that, lol.) At first, only The Dude’s Nexus would overclock to 1.267GHz and for that reason, it was dubbed the “JesusPhone” or JP1.”

Fixing things with Linpack App and Reporting

I’m slowly getting some things fixed with the Linpack for Android app.  I’m adding information about MHz used and hopefully some reporting directly into the app on where it scores on the master list.

I’ve also fixed a big error on my part dealing with MFLOPS.  For some reason, I had it listed here and in the app as Mflops/s.  Oops, that would mean Million of Floating Point Operations per second per second.  It would be cool to measure acceleration, but that is not what it reports.

Droid running at 50.592 MFLOPS

So I check out the top devices list and see a score of 50.592 MFLOPS for a Droid from Jw52637.  Wow, 50.592!!
How did Jw52637 get that?  Is he/she running the new Dalvik Turbo?  or was it overclocked to the point it was melting?

I hope it’s the Dalvik Turbo.  As Myriad said in their press release the other day; “Dalvik Turbo increases application execution speed by up to three times ‐ allowing OEMs and operators to bring smoother delivery and more complex applications to Android phones, while also providing substantial battery life improvements when running resource intensive tasks. It also enables developers to take full advantage of Android, allowing them to create games boasting advanced graphics and complex models while retaining full compatibility with existing software.”

T-Mobile G1 Overclocked and Android 2.1 Times

I updated the Linpack Device listings to better show the T-Mobile G1 overclocking and runs utilizing replacement ROMs.  It looks like the overclocked G1 using a stock ROM is still edging out the Android 2.1 ROMs by about 11%.  I just wonder how fast the G1 was overclocked to get that number.  Me, I’ll wait for the 2.1 update that will HOPEFULLY come soon.

Over 5000 Linpack Downloads

Thanks to all of you who’ve downloaded Linpack for Android. I’m planning on updating the results pages and cleaning up the user interface. Any constructive comments are welcome on improvements.
