Hi, Yogi,
I see you are trying to run Norne with 144 processes. Did you see the problem
with much less processes, for example 4 or 8 processes?
In my opinion, with the current approach for domain decomposition, it can be
challenging to run Norne with so many processes, considering the relative
Hello everyone,
I am trying to run steadystate_test_upscaling (from opm-upscaling) on a
primary drainage case, and I am struggling to get convincing results.
No matter what capillary number I use, the output relperms stay the
same (down to the last digit).
We are suspecting it might have to do wit

Hi Yogi,
Lots of things have changed in Flow for the initialization in parallel
recently. Could you try to check out the previous release (2019.10) and check
if you see the same problems?

Dear opm community;
we are approaching April and the 2020.04 release of opm/flow is soon
imminent, and it is time to start planning the release process. If someone
has planned to be the release manager for the 2020.04 release that is cool,
otherwise opm-op can be responsible for managing the 2020.
Hi Kai,
Thank you for your reply. I have run the Norne model with 1, 2, 4, 8, 16, 36,
72, and 108 processes successfully. The run gets stuck at 144 processes. As I
mentioned, I did try a larger model, but even there I was not able to scale on
more than 1 node for a certain configuration. Fin
Hi Dr. Blatt,
I am using OPM Flow version 2020.04-pre. Each node has 384 GB memory, and I
don't see any memory problem indicated by kswapd appearing.
With some hit and trial I arrived at a model with just 1 producer and 1
injector, with 11 million cells, which scales on 4 nodes. My impression i
Dr. Blatt,
That's a typo. Each node has 36 processors.
Thank you,
Yogi

Thank you for the suggestion Atgeirr. I'll try out the previous release 2019.10.
