- gather/scatter types of operations can avoid AllToAll communication
and use simple MPI gather (or scatter) to establish the receive sizes.
New methods: finishedGathers() / finishedScatters()
- returns a range of `int` values that can be iterated across.
For example,
for (const int proci : Pstream::subProcs()) { ... }
instead of
for
(
int proci = Pstream::firstSlave();
proci <= Pstream::lastSlave();
++proci
)
{
...
}
- returns a range of `int` values that can be iterated across.
For example,
for (const int proci : Pstream::allProcs()) { ... }
instead of
for (label proci = 0; proci < Pstream::nProcs(); ++proci) { ... }
