3.1 AMPI Status

Currently all the MPI-1.1 Standard functions are supported in AMPI, with a collection of our extentions explained in detail in this manual. One-sided communication calls in MPI-2 are implemented, but they are not taking advantage of RMA features yet. Also ROMIO³ has been integrated to support parallel I/O features. Link with -lampiromio to take advantage of this library.

Following MPI-1.1 basic datatypes are supported in AMPI. (Some are not available in Fortran binding. Refer to MPI-1.1 Standard for details.)
