This is a potentially expensive operation and so we should not run
it unless such values are actually needed for output purposes (e.g.,
inter-region flow summary vectors).
This commit ensures that compute inter-region flow rates on all
ranks and collect those on the I/O rank using CollectDataToIORank.
We add a trivial EclInterRegFlowMap data member to the communication
object. This data member only knows the pertinent FIP region array
names, but uses existing read/write support to collect contributions
from all ranks into this "global" object. We then pass this global
object on to the summary evaluation routine.
This commit introduces a new helper class
Opm::EclInterRegFlowMapSingleFIP
that wraps a vector of
Opm::EclInterRegFlowMapSingleFIP
along with the associate array names (e.g., "FIPNUM" and any
additional "FIP*" arrays). We implement the same operations as the
*SingleFIP type and simply loop over the internal accumulators to
affect the operations.
Add unit tests to exercise the new class, including simulating
multiple MPI ranks that are communicated to a single I/O rank for
summary output purposes.
This commit introduces a new helper class
Opm::EclInterRegFlowMapSingleFIP
that wraps an object of type
Opm::data::InterRegFlowMap
along with the MPI rank's notion of a FIP region array definition
(e.g., the local FIPNUM array). The new single-FIP flow map is
responsible for accumulating local contributions to the inter-region
flows defined by that FIP array. In the case of connections between
MPI ranks, the rank that owns the lowest region ID accumulates the
associate flow rates.
Add unit tests to exercise the new class, including simulating
multiple MPI ranks that are communicated to a single I/O rank for
summary output purposes.
