Markus,
I tried running this deck in sequential mode in an Ubuntu VM and it just
fails:
david at EIPC02-VirtualBox:/media/sf_Linux/OPM-Flow/spe10model2$ flow
SPE10_MODEL2.DATA
**********************************************************************
* *
* This is flow 2018.04 *
* *
* Flow is a simulator for fully implicit three-phase black-oil flow, *
* including solvent and polymer capabilities. *
* For more information, see https://opm-project.org *
* *
**********************************************************************
Killed
david at EIPC02-VirtualBox:/media/sf_Linux/OPM-Flow/spe10model2$
I ran under strace and got
david at EIPC02-VirtualBox:/media/sf_Linux/OPM-Flow/spe10model2$ tail
