The functions call MPI info functions.
info.create(info = .pbd_env$SPMD.CT$info) info.set(info = .pbd_env$SPMD.CT$info, key, value) info.free(info = .pbd_env$SPMD.CT$info) info.c2f(info = .pbd_env$SPMD.CT$info)

These functions are for internal functions. Potentially, they set info for initialization of master and workers.
