Re: [eigen] Running CTest with MKL Enabled

[Kevin Locke <kevin@xxxxxxxxxxxxxxx>]

Thanks Gael, much appreciated!

Is it alright if I ran the tests with GCC and/or Clang rather than ICC?
I am not very familiar with ICC and don't currently have it installed on
the build machines.

I gave it a try and uploaded the result to CDash at
http://manao.inria.fr/CDash/buildSummary.php?buildid=16748

The commands that I used were:
CC="clang-3.5" CXX="clang++-3.5" cmake .. \
-DEIGEN_TEST_CUSTOM_CXX_FLAGS="-I$MKLROOT/include -DEIGEN_USE_MKL_ALL" \
-DEIGEN_TEST_CUSTOM_LINKER_FLAGS="-lmkl_sequential -lmkl_intel_lp64 \
-lmkl_core" -DCMAKE_BUILD_TYPE=Release -DEIGEN_TEST_BUILD_FLAGS=-j4
ctest -j4 -D Nightly

Does that seem about right?  If so, I'll try to run it on a more regular
basis.  If there's anything I can change to make it more useful, don't
hesitate to point that out.

Thanks,
Kevin
