static MPI_Datatype casa::ExecRecord::datatype ( ) [inline, static]

It might be nice to have static class members to hold the MPI datatype and reduction op, but since they can only be computed at run-time, that would require a mutex and lock (the computation would have to be in a critical section).

In turn that would require acquiring the lock every time the datatype is accessed, which is something that we'd like to avoid.

to capture padding for alignment of structures, we resize dt
