Hmm, I had already fixed this, I think,

but unfortunately our backlog of pull requests kept it out of master. We are
(well Satish and Jed) working on a new CI infrastructure that will

Perhaps my earlier messages was not clear. The problem is not with
OpenMPI - but your build of it. Its installed with 'clang' as the C++
compiler - it should be built with 'cl

Myriam:
Very interesting results. Do you have time for petsc-3.10 (blue) and 3.6
(green)?
I do not understand why all algorithms gives non-scalable memory performance
except petsc-3.6. We can easily resume petsc-3.6's MatPtAP though.

Hi,
I plotted new scalings (memory and time) using the new algorithms. I
used the options /-options_left true /to make sure that the options are
effectively used. They are.
I don't have access to the platform I used to run my computations on, so
I ran them on a different one. In particular, I can
