It may be useful to explain a bit more how Linpack works and is optimized for given platform. It has 40-50% higher rate of solving (gives higher gigaflops rating), produces much much higher temps (considerably higher than TAT, and much higher than Prime) and is exceptionally good for error catching, both for CPU and memory errors. The 32bit version produces good load and is also good for error catching, but to really stress Core2 CPU, 64bit version should be used. Linpack fails the test, though it will continue to work. It should be small, on the order of 10-02 (0.01),Īnd should not change from run to run with the same problems size.

The most interesting fields for us are: the fifth value, which is Gigaflops rating obtained in this run, and the seventh, which is Residual (norm) value. Never mind the Error: info returned = 1 string, this is not actually an error and harmless. This does not affect the results in any way.įor each tests ran, there will be a string with 7 fields, like this The program incorrectly determine my Q6600's speed, which is 3.328GHz (8x416). Maximum memory requested that can be used = 7938634096, at the size = 31500 Number of equations to solve (problem size) : 31500 Here is the example part of the output file for problem size 31500: The progress can be conveniently monitored in another Far instance with F3 viewer. The results will be in file with the name lin_xeon(32,64).txt.

The best way is to run it from Far manager (google Far manager and download it, its free) or similar program. To run the test, run runme_xeon(32,64).bat. Small problem size can be used to test CPU, or large problem size can be used to test both CPU ( more extensively) and all available memory. The problems size for the test may be set arbitrary small, however bigger problem size will produce higher benchmark result.

The example file for 8GB RAM under Win X64 (Linux 圆4 actually, but the file is the same) will look like this: Set less for quick test, set 1 for only one pass) (It may take several hours for the benchmark to complete. Set the same number in the next field #leading dimensions Set only the maximum problem size in the # problem sizes field For 4GB memory (needs 64bit OS to see), 3.5GB can be used for Linpack test, this amounts to sqrt(3 500 000 000/8) ~ 21000 problem size. So, for the problem size 10000 the amount of memory would be 800MB. In any case, do not let the test run from disk swap! The amount of memory Linpack uses is equal 8x (Problem size)^2. The rule is simple : take the whole amount of memory you see in your OS, subtract 500MB for the OS needs (may need more for memory-hungry Vista), the rest can be assigned to Linpack job. Determine the maximum problem size your memory can hold.

Here is the instruction on how to properly use Linpack for stability testing:
#Goal of linpack benchmark software
The software can be downloaded from Intel: The software solves mathematical problem - arbitrary large set of linear equations, and displays the rate of solving, measured in Gigaflops. Cluster Linpack version can be used to measure performance of computational clusters, and even huge Super-Computers. The primary goal of this benchmark is to measure Gigaflops rating of (Intel) CPU(s). Introducing the Intel Linpack benchmark, the most stressing and demanding benchmark/stability test ever! Seeing how the importance of proper stability testing is slowly getting more evident among XS members, i want to invite everyone to put their Intel CPUs, primarily new Core2, into really stressing stability test.
