Linpack for Android

Linpack for Android


Speed test your Android device and ROM with this standard CPU benchmark. Check the speed of your Android device and compare it to other Android devices. Results in millions of floating point operations per second (MFLOPS). Save results or post to the website to beat the best times.

Note: Your MFLOPS rating will increase in this version due to updated libraries and methods. Shows Android is improving! Newly added the ability to fully test multi-core processors with the use of multi-threading. Compare speeds from a single and multi-thread runs. See how well your multi-core device works under android.

The Linpack for Android application is a version created from the original Java version of Linpack created by Jack Dongarra. That version is located at netlib.org

The LINPACK Benchmarks are a measure of a system’s floating point computing power. Introduced by Jack Dongarra, they measure how fast a computer solves a dense N by N system of linear equations Ax = b, which is a common task in engineering. The solution is obtained by Gaussian elimination with partial pivoting, with 2/3*N3 + 2*N2 floating point operations. The result is reported in Millions of FLoating-point Operations Per Second (MFLOP/s, sometimes simply called FLOPS).

This test is more a reflection of the state of the Android Dalvik Virtual Machine than of the floating point performance of the underlying processor. Software written for an Android device is written using Java code that the Dalvik VM interprets at run time.

Questions asked about the app:
What is the purpose of this app?
This is a simple benchmark test to show performance relative to other phones for a standard calculation. Linpack has been used for years on all types of computers, with a version used to rate the TOP500 computers in the world.

What speed is better?
A higher number is better. From the Top Devices list, you can see that each device has a certain range that they all come in at. What can affect the number is what else is running on android and the ROM version. It appears that Android 2.0 will also improve performance.

Does having faster speed improve the android phones or what?
Yes, it should. The Dalvik VM has a huge impact on the Linpack number. A better number on the same device would indicate that a new version update has improved performance. Or it could show that something has gone terribly wrong if the number goes down.

Recent changes:
V1.2.8 – Updated Multi-threading to improve consistency of calculations. Increased calculations performed.
V1.2.7 – Added Multi-threading. This will allow multi-core devices to test how well they operate under Android with multi-threading.
V1.2.6 - Fix Force Close on Install
V1.2.5 – Changed Top10 and Latest Posts from website links to internal forms. Began changes to the code to handle multiple cores in a future release. This version is not yet multi-threaded.

great test

Good mflop benchmark

Perfect when used with performance improvement apps like SetCPU to check if your device/ROM is better off or worse. Nice work and does *exactly* what is says.

Oc seems useless It seems useless to oc with custom roms or stock roms nowadays. Someone got 1216 with 2.9ghz I get 1198 with stock. Is it me or is it useless these days or what? Im sticking to stock. 24900 atutu note 3 lte 1198 linpack. STOCK!!
