Before the TS, the concept of ASYNCHRONOUS applied only to I/O. Asynchronous use of a variable started with a READ or WRITE statement and completed with a WAIT statement. The TS extended that idea to “asynchronous communication” that could also include the effects of non-Fortran procedures (specifically like MPI_Ixxx routines).

Could you give some background/details on the "new" meaning ASYNCHRONOUS? I thought Intel ifort had support?

I’ve been using gfortran 4.9 for some time to compile mpi_f08 and associated modules. But not execute. The Cray compiler does support the C descriptors, but gfortran is not quite there yet. I think the gfortran plan is to switch all of their dope vectors to the C descriptor format, which is a much bigger change.
