Hi,

It seems to me, that two of the tests in the test-suite took extraordinary long time especially on my machine.
These are product_large with about 120s and lu with about 180s.

At no time, I've found such long timings by my "cdash-competitors".
Not in the near past, nor months ago. Beside these two tests, no other test is "off the field".

What may the reason(s) for this?

Regards
Frank

P.S.
One of my old and unsolved queries is: How can i submit some special compiler flags (in)to the test suite, like "-Ox" ?

Tests take long to compile because we try to test as many different things as possible, and since this is a pure template library, every different operation we try means for the compiler more types to instantiate. To make things worse, we try many different matrix types.

Regarding compiler options, you can always edit tests/CMakeLists.txt, scroll down to where we do many ei_add_test's, you'll see that the 2nd parameter allows you to pass compiler options, and some already have.

Thank you, I will take a look into cmakelists.txt

Ehm.. I have to rephrase my question:
...extraordinary long run time... product_large.exe 120s, lu.exe 180s, why?
What I am puzzled with, is that other people do record run times (not compile times) in an order of magnitude better for this two particular tests and the rest of the test suite is more or less in par. That is what i have called "extraordinary", not a long time per se.

So, I'm intersected in possible reasons for that phenomenon.

Ah, ok. So the thing is that the two tests that you mention are so heavy (runtime-wise) that we enable (in the cmakelists) optimization flags (-O2) for them, so that they don't take too long to run. It seems that for some reason these optimization flags get overridden for you.

FMD, please take a look at the CMakeCache.txt file of those builds.

Could it be that CMAKE_BUILD_TYPE:STRING=Debug ?

That just happened to me today! The issue is that on Windows in debug mode the optimization flag Benoit talked about is completely disabled. I have not yet any clue why ctest is per default running in Debug but I have a patch which I could submit.
