Rmpi

mpi.exit

Exit MPI Environment

Description

mpi.exit terminates MPI execution environment and detaches the library Rmpi. After that, you can still work on R.

mpi.quit terminates MPI execution environment and quits R.

Usage

mpi.exit()
mpi.quit(save = "no")

Arguments

save

the same argument as quit but default to "no".

Details

Normally, mpi.finalize is used to clean all MPI states. However, it will not detach the library Rmpi. To be more safe leaving MPI, mpi.exit not only calls mpi.finalize but also detaches the library Rmpi. This will make reload the library Rmpi impossible.

If leaving MPI and R altogether, one simply uses mpi.quit.

Value

mpi.exit always returns 1
