Hi,

I cannot reproduce this.

I have set up a testing-i386 chroot (on my amd64 laptop) and installed
openmpi from unstable (I also tried with mpi4py from unstable on top),
as well as their versionned dependencies not in testing:

libopenmpi-dev 4.1.1-5
libopenmpi3    4.1.1-5
openmpi-common 4.1.1-5
python3-mpi4py 3.0.3-10

I tried with gyoto from unstable (1.4.4-4) and from testing (1.4.4-3).

Note that this is apparently different from what the debci
infrastructure does (apparently recompiling instead of taking the binaries).

I then ran the test from this chroot (as sbuild user):
autopkgtest -B --test-name=gyoto-mpi -- null

The test PASSED each time.

I note that the test suite can take a long time to run and that the
final line in the failure log for this test reads:

mpirun.openmpi noticed that process rank 1 with PID 0 on node
ci-262-d8ad913b exited on signal 9 (Killed).

This happens after this test has been running for 1h and 55min.

Could it be that the process is killed because of a timeout in the test
environment?

In the one hand it would feel strange because, on the debci
infrastucture, the error always happens on the same file
(example-startrace), near the beginning of the process (row 1/32). On
the other hand I know this file is one of the longest to process (still
below a couple of minutes on my laptop).

Anyway, there's not much more I can do, except skip this test.

I'm reassigning to openmpi because, on the debci infrastructure, the
same failure occurs with openmpi/unstable also with mpi4py/testing.

Advice welcome.

Regards, Thibaut.
