Aha, it looks like you have found a bug. Congratulations! A similar problem
was discussed in https://trac.einsteintoolkit.org/ticket/1936#comment:4 for the
QuasiLocalMeasures thorn. The solution is to merge the multiple tags entries.
It's called "development version" for a reason :) There is also a problem with
the ADMConstraints thorn. I have fixed both of these. You should be able to
update using
cd Cactus_ETK_dev
repos/CRL/GetComponents --update --root .
(I don't use GetComponents, so I'm guessing that this is the recommended way to
update)
The reason this is not caught by the automated tests is that the WaveExtractCPM
thorn is not part of the toolkit thornlist, so is not tested. It is used in
the GW150914 parameter file and thornlist, because I thought it was a useful
thing to have, though it is by no means essential. The Cactus parser has been
rewritten since this was last tested, and the new version is much stricter.
This is good, because the old behaviour was to ignore all but the last of
repeated tags entries, which is definitely not what was intended here!
I don't think that this bug would affect results; the code will currently
ignore the first tags entry specifying the tensor type, but that would only be
used for symmetry boundary conditions, which shouldn't be relevant for the
metric_tmp gridfunction, since it is a temporary variable which is probably
only accessed point-wise.

You will need to be more specific about what you mean by "analyse the
performance". What do you want to know?

I didn't understand the email that you sent about this. We said that the bug
was in the Intel 17 compiler, and that you should be able to fix the problem by
using the development version of the toolkit, since a workaround has been added
there. It looks like you are now using the development version, so the problem
shouldn't be there any more. Does the development version still not work?
