complete, but stable enough that it will have no impact on general development, so into the trunk it goes. Changes in this commit include: - Remove the --with option for disabling MPI-2 onesided support. It complicated code, and has no real reason for existing - add a framework osc (OneSided Communication) for encapsulating all the MPI-2 onesided functionality - Modify the MPI interface functions for the MPI-2 onesided chapter to properly call the underlying framework and do the required error checking - Created an osc component pt2pt, which is layered over the BML/BTL for communication (although it also uses the PML for long message transfers). Currently, all support functions, all communication functions (Put, Get, Accumulate), and the Fence synchronization function are implemented. The PWSC active synchronization functions and Lock/Unlock passive synchronization functions are still not implemented This commit was SVN r8836.

|
|
* have four symbols for each of the common blocks (e.g., the Fortran
|
|
* equivalent(s) of MPI_STATUS_IGNORE). Here, we can only have *one*
|
|
* value (not four). So the only thing we can do is make it equal to
|
|
* the fortran compiler convention that was selected at configure
|
|
* time. Note that this is also true for the value of .TRUE. from the
|
|
* Fortran compiler, so even though Open MPI supports all four Fortran
|
|
* symbol conventions, it can only support one convention for the two
|
|
* C constants (MPI_FORTRAN_STATUS[ES]_IGNORE) and only support one
|
|
* compiler for the value of .TRUE. Ugh!!
|
|
*
|
|
* Note that the casts here are ok -- we're *only* comparing pointer
|
|
* values (i.e., they'll never be de-referenced). The global symbols
|
|
* are actually of type (ompi_fortran_common_t) (for alignment
|
|
* issues), but MPI says that MPI_F_STATUS[ES]_IGNORE must be of type
|
|
* (MPI_Fint*). Hence, we have to cast to make compilers not
|
|
* complain.
