This will allow multi-core devices to test how well they operate under Android with multi-threading.

V1.2.8 – Updated Multi-threading to improve consistency of calculations. Or it could show that something has gone terribly wrong if the number goes down.
Note 4 linpack benchmark update#
A better number on the same device would indicate that a new version update has improved performance. The Dalvik VM has a huge impact on the Linpack number. It appears that Android 2.0 will also improve performance.ĭoes having faster speed improve the android phones or what? What can affect the number is what else is running on android and the ROM version. From the Top Devices list, you can see that each device has a certain range that they all come in at. Linpack has been used for years on all types of computers, with a version used to rate the TOP500 computers in the world.Ī higher number is better. This is a simple benchmark test to show performance relative to other phones for a standard calculation. Software written for an Android device is written using Java code that the Dalvik VM interprets at run time. 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. The result is reported in Millions of FLoating-point Operations Per Second (MFLOP/s, sometimes simply called FLOPS). The solution is obtained by Gaussian elimination with partial pivoting, with 2/3*N3 + 2*N2 floating point operations. 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 LINPACK Benchmarks are a measure of a system’s floating point computing power.

The Linpack for Android application is a version created from the original Java version of Linpack created by Jack Dongarra. See how well your multi-core device works under android. Load temp under Linpack will be up to 22C higher than the competing software Prime95. Compare speeds from a single and multi-thread runs. Linpack by Intel(R) is an extremely stressful program that will put even the most pow-erful X86/X64 CPU in the world at its knees. Shows Android is improving! Newly added the ability to fully test multi-core processors with the use of multi-threading. Note: Your MFLOPS rating will increase in this version due to updated libraries and methods. Save results or post to the website to beat the best times. Results in millions of floating point operations per second (MFLOPS). At first, we had difficulty improving HPL performance across nodes. The specs are: 6 x86 nodes each with an Intel(R) Xeon (R) CPU 5140 2.33 GHz, 4 cores, and no accelerators. HPL rely on an efficient implementation of the Basic Linear Algebra Subprograms (BLAS). It is used as reference benchmark to provide data for the Top500 list and thus rank to supercomputers worldwide.

Check the speed of your Android device and compare it to other Android devices. We’ve been working on a benchmark called HPL also known as High Performance LINPACK on our cluster. HPL is a portable implementation of the High-Performance Linpack (HPL) Benchmark for Distributed-Memory Computers. These operations are performed by the Level 3 BLAS in most cases.Speed test your Android device and ROM with this standard CPU benchmark. We use the term “Transportable” instead of “portable” because, for fastest possible performance, LAPACK requires that highly optimized block matrix operations be already implemented on each machine. For each computer architecture, block operations can be optimized to account for memory hierarchies, providing a transportable way to achieve high efficiency on diverse modern machines. LAPACK addresses this problem by reorganizing the algorithms to use block matrix operations, such as matrix multiplication in the innermost loops. The memory access patterns of the algorithm have disregard for the multi-layered memory hierarchies of RISC architecture and vector computers, thereby spending too much time moving data instead of doing useful floating-point operations. This is mainly due to the way the algorithm and resulting software accesses memory. Q: Is Linpack the most efficient way to solve systems of equations?Ī: Linpack is not the most efficient software for solving matrix problems.
