MPI standard. If an MPI doesn't actually implement MPI_INIT_THREAD or any threading support, it may still be possible to make limited use of a hybrid model, for , with 1 MPI process per node. That may often be an acceptable limitation.This is getting more into the territory of ...
Currently, MPI File operations are not thread safe even if MPI is initialized for MPI_THREAD_MULTIPLE support. MPI_REAL16 and MPI_COMPLEX32 are only supported on platforms where a portable C datatype can be found that matches the Fortran type REAL*16, both in size and bit representation. ...
