Performance of ElmerSolver on different platforms

[raback]

Hi All,

After the introduction of labels in ctest it is rather easy to run a simple performance test on Elmer. The tests with label 'benchmark' may be run with

Code: Select all

ctest -L benchmark 

This should give roughly the following ouput:

Code: Select all

elmeruser@elmeruser-VM64bit ~/Source/builddir $ ctest  -L benchmark
Test project /home/elmeruser/Source/builddir

100% tests passed, 0 tests failed out of 14

Label Time Summary:
benchmark    = 177.41 sec

Total Test time (real) = 177.77 sec

The tests can be used for mainly for two purposes
1) To rate the performance of different platforms for typical small Elmer cases
2) To ensure that the code does not become slower after new features are introduced

Because we cannot guarantee exact same performance between versions it may not really be useful to compare different platforms with different Elmer versions. Still we hope that this could be of use.

I encourage everybody to run the tests and specify their setup and code performance.
