Re: [eigen] CDASH-Speedup: "Homer" how did you do it?

[ Thread Index | Date Index | More Archives ]

It was actually as I wrote on the forum. For some strange reason,
CMake uses the 'Debug' profile for creating dashboards when using the
testsuite script. You can verify this by checking your CMake cache.
Furthermore, optimization is even for the tricky unit tests disabled
on Windows machines, i.e. the EI_OFLAG is never set.

To achieve the run-times as on the dashboard I patched the
test\testsuite.cmake file. It is not yet comitted since I added two
more changes which probably need their ok from Gael or Benoit.

1) I added a IGNORE_CVS flag

That allows me to change files locally and still be able to submit to
dashboards via the testsuite script. See batch file for an example.

2) I added CMake cache settings for CMAKE_BUILD_TYPE

This is what you are actually looking for...

3) I disabled setting the CTEST_ENVIRONMENT CXX on Windows.

This is because CXX must be a proper CMake known value, e.g. MSVC. On
the other hand we use it in the build string when it is not set by the
user and typically we also want the version number of the compiler
which is not supportet for MSVC.

So, if nobody objects, I will submit this.

I also have a small patch for cmake/EigenTesting.cmake regarding the
EI_OFLAG. I basically force overriding the debug compile flags and
remove the run-time checks and thus enable us to set EI_OFLAG to O2.
It seems to work here on my machine. This is again not required for
the speedup since O2 is automatically set in Release mode - but in
case somebody goes back to debug he does not have to wait for 70+
minutes for the unit tests to finish...
