|MPI array pointers||R Documentation|
The function set/get a point address in R where the point point to a structure containing MPI arrays.
Since Rmpi/pbdMPI use pre-allocate memory to store comm, status, datatype, info, request, this function provides a variable in R to let different APIs share the same memory address.
If the package loads first, then this sets '
.GlobalEnv of R. If the package does not load before other
MPI APIs, then this points an structure point to the external memory
according to '
.__MPI_APTS__', i.e. pre-set by other MPI APIs.
pbdMPI/R/arrange.mpi.apts provides the R code, and
pbdMPI/src/pkg_*.* provides the details of this call.
.__MPI_APTS__' is set in the
.GlobalEnv of R.
