Re: [eigen] 3.3.8 expected on September 7

Hi Nobert,

Thanks that's really great and Arm64 support is something are absolutely interested in!

In fact, I work for Arm and as you might have seen, quite a lot of work has already been done in Eigen's Arm backend, however this is for master and not 3.3. Together with Arm we were able to allocate Arm64 hardware for nightly CI test jobs. Tbh, the only thing missing is me integrating it but this is planned for this week.

In short: We are happy about every contribution to our CDash dashboard, but in the (hopefully not so) long run it will most likely be replaced by GitLab CI with runners for x86_64, Arm64 and PPC. As soon as this is finished I'll make a general announcement but here is a first example for Linux x86_64 for master:

I used Gael's mail as a motivation to run tests on ARM64. I was mainly
struggling with reporting to CDash in conjunction with our company
network, hence there were multiple runs.

As there are different tests failing in different runs I suspect the
tests to be failing because of either misconfiguration on my side or
missing resources on the test runner.

Before investigating the failing tests any further I'd like to clarify
whether these runs on ARM64 are of any use to you. They require (and
always will I'm afraid) some amount of manual work to run, so I could
try to run these tests semi-regularly if needed - but only if needed.

Dear all,

let me start by taking this opportunity to thank David for
revitalizing Eigen's developpement.

Thank to that, at long last we're having a new release of the stable
3.3 branch within a few days. Since it receives many more changesets
than usual for such a minor release, it would be very welcome if some
of you could test it with your favorite compiler and options:

git clone -b 3.3 eigen3.3
cd eigen3.3
mkdir build
cd build

# run cmake adapting the options to your Eigen's usage, e.g.:
CXX=clang++-9 cmake  ... -DEIGEN_TEST_BUILD_FLAGS="-j 8"

# run ctest while submitting to cdash:
ctest -V -D Experimental -j 8
