Hi,
Nice to hear that there is some work on the output layer. I just have
some questions.

[...] In the ACROSS project (see https://www.acrossproject.eu for
information), we intend to implement parallel output for OPM Flow. The
idea is to do this by using the Damaris software library
(https://project.inria.fr/damaris/) from INRIA, who are also part of
the ACROSS project, and will contribute to the implementation. We think
Damaris is a good fit for OPM. It is open source, has been shown to
provide good I/O scaling up to large process counts, and has been
previously applied in the reservoir simulation domain.
Can you please tell us what open source license Damaris uses. I could
not find any information on the website and at
https://gitlab.inria.fr/Damaris/damaris it says "No license. All rights
reserved", but that is probably an oversight. No License file, no
readme.
Can you point us to a publication where it is used for reservoir
simulation? That would be interesting.
So far, we see three important tasks related to this:
- Refactoring in OPM Flow to enable the integration of Damaris. From what we
have seen so far, any necessary refactoring will be improving the Flow code,
and make it more flexible.
- Integrating the Damaris library. We will ensure that this is an optional
dependency, to minimize developer workload and hassle.
What does optional mean here? If there is no Damaris we fall back to our
current way and only if it is there we get hdf5/parallel output? Or are
there plans to support hdf5 without Damaris (which seems to be a lot
more than just output: data processing, in situ visualization,...)? That
would be cool.
Cheers,
Markus
