This commit adds a new container class,
ParallelPAvgDynamicSourceData
which inherits from PAvgDynamicSourceData and provides a parallel
view of source contributions. Member function
collectLocalSources
will call the user-provided source term evaluation function for each
source location in its purview--typically those locations owned by
the current MPI rank. Those values will be distributed to other MPI
ranks through member function synchroniseSources which will fill the
base class' 'src_' data member, and become available to clients
through read-only item spans.
There is a strange interaction when using MPI and OpenMP on some
hardware/MPI implementations. I a serial run omp_get_num_procs() would
return the number of processors but when started under mpirun it would
always return 1.
With this we now allow users to use any amount of threads.
While we reported that we used the number of threads that were passed
on the command line, we never really used it for OpenMP but always
sticked to two unless environment variable OMP_NUM_THREADS was set.
Note that because the ThreadManager in opm-models would always use the
command line option and hence the linearizer would use that number of
threads.
Please note that the only use of OpenMP in opm-common (volume
calculation in EclipseGrid) is not effected by this as it happens
before we set the number of OpenMP threads.
These can be used to manage state in the well models, and will
be used in the NLDD solver option. Also added the setupDomains()
method, as the getters and setters are working on a domain basis.
With zero threshold pressure and zero pressure difference, the existing code will
set the pressure diff explicitly to zero. This will also set any derivatives to
zero as well, which may disconnect the corresponding matrix rows.
This initial commit changes the API of the CollectDataToIORank
class' handling of WBPn values from collecting a set cell pressures
into communicating pre-computed WBPn values through the new
WellBlockAveragePressures container class. This is in preparation
of moving the WBPn calculation to the simulator side for greater
parallelism. For now we do not compute any of the actual WBPn
values. That will be the subject of follow-up commits.
While here, also split a number of very long lines for readability.
