Fixing things with Linpack App and Reporting
Feb 21st
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
Feb 12th
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
Feb 3rd
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.
Cyanogen is a god

WOW! Cyanogen has done it again. I started seeing a new version of CyanogenMod ROM (version 5 beta) showing up on the list for the Nexus One. How does a 245% speed improvement sound? Holy Smoke! Almost 2.5X faster!! How’s he doing it? It looks like JIT can be turned on. JIT is the Just In Time compiler for Dalvik.
Wayback a year ago, a paper and presentation was put out about performance on Android. This was done by a team from the Berlin Technical University. The presentation was my inspiration to get Linpack for Android working. A couple of the things that they pointed out that hinder Android was that there was 1) No Just-in-Time compilation and it was 2) Optimized for small footprint, not raw performance. It looks like Cyanogen is fixing that problem. I wonder if it could help my G1?
