The default odls has been updated and works fine. The process odls has been updated, but I could not verify its operation. The bproc ODLS has not been updated yet. Ralph will look at it soon. This commit was SVN r15257.

|
*
|
|
* Setup the predefined attributes in MPI.
|
|
*
|
|
* A number of pre-defined attributes are created here, most of which
|
|
* are exactly what one would expect, but there are a few exceptions
|
|
* -- so they're documented here.
|
|
*
|
|
* Predefined attributes are integer-valued or address-valued (per
|
|
* MPI-2; see section 4.12.7, keeping in mind that Example 4.13 is
|
|
* totally wrong -- see src/attribute/attribute.h for a lengthy
|
|
* explanation of this).
|
|
*
|
|
* The only address-valued attribute is MPI_WIN_BASE. We treat it as
|
|
* if it were set from C. All other attributes are integer-valued.
|
|
* We treat them as if they were set from Fortran MPI-1 (i.e.,
|
|
* MPI_ATTR_PUT) or Fortran MPI-2 (i.e., MPI_xxx_ATTR_SET). Most
|
|
* attributes are MPI-1 integer-valued, meaning that they are the size
|
|
* of MPI_Fint (INTEGER). But MPI_WIN_SIZE and MPI_WIN_DISP_UNIT are
|
|
* MPI-2 integer-valued, meaning that they are the size of MPI_Aint
|
|
* (INTEGER(KIND=MPI_ADDRESS_KIND)).
|
|
*
|
|
* MPI_TAG_UB is set to a fixed upper limit.
|
|
*
|
|
* MPI_HOST is set to MPI_PROC_NULL (per MPI-1, see 7.1.1, p192).
|
|
*
|
|
* MPI_IO is set to MPI_ANY_SOURCE. We may need to revist this.
|
|
*
|
|
* MPI_WTIME_IS_GLOBAL is set to 0 (a conservative answer).
|
|
*
|
|
* MPI_APPNUM is set as the result of a GPR subscription.
|
|
*
|
|
* MPI_LASTUSEDCODE is set to an initial value and is reset every time
|
|
* MPI_ADD_ERROR_CLASS or MPI_ADD_ERROR_CODE is invoked.
|
|
* Its copy function is set to
|
|
* MPI_COMM_NULL_COPY_FN, meaning that *only* MPI_COMM_WORLD will have
|
|
* this attribute value. As such, we only have to update
|
|
* MPI_COMM_WORLD when this value changes (i.e., since this is an
|
|
* integer-valued attribute, we have to update this attribute on every
|
|
* communicator -- using NULL_COPY_FN ensures that only MPI_COMM_WORLD
|
|
* has this attribute value set).
|
|
*
|
|
* MPI_UNIVERSE_SIZE is set as the result of a GPR subscription.
|
|
*
|
|
* MPI_WIN_BASE is an address-valued attribute, and is set directly
|
|
* from MPI_WIN_CREATE. MPI_WIN_SIZE and MPI_WIN_DISP_UNIT are both
|
|
* integer-valued attributes, *BUT* at least the MPI_WIN_SIZE is an
|
|
* MPI_Aint, so in terms of consistency, both should be the same --
|
|
* hence, we treat them as MPI-2 Fortran integer-valued attributes.
|
|
* All three of these atrributes have NULL_COPY_FN copy functions; it
|
|
* doesn't make sense to copy them to new windows (because they're
|
|
* values specific and unique to each window) -- especially when
|
|
* WIN_CREATE will explicitly set them on new windows anyway.
|
|
*
|
|
* These are not supported yet, but are included here for consistency:
|
|
*
|
|
* MPI_IMPI_CLIENT_SIZE, MPI_IMPI_CLIENT_COLOR, MPI_IMPI_HOST_SIZE,
|
|
* and MPI_IMPI_HOST_COLOR are integer-valued attributes.
