Started to update the NEWS file for v1.5. Might need a few more
tweaks. This commit was SVN r23358.

NEWS
@ -26,6 +26,27 @@ This file contains the main features as well as overviews of specific
|
||||
bug fixes (and other actions) for each version of Open MPI since
|
||||
version 1.0.
|
||||
|
||||
As more fully described in the "Software Version Number" section in
|
||||
the README file, Open MPI typically releases two separate version
|
||||
series simultaneously. Since these series have different goals and
|
||||
are semi-independent of each other, a single NEWS-worthy item may be
|
||||
introduced into different series at different times. For example,
|
||||
feature F was introduced in the vA.B series at version vA.B.C, and was
|
||||
later introduced into the vX.Y series at vX.Y.Z.
|
||||
|
||||
The first time feature F is released, the item will be listed in the
|
||||
vA.B.C section, denoted as:
|
||||
|
||||
(** also to appear: X.Y.Z) -- indicating that this item is also
|
||||
likely to be included in future release
|
||||
version vX.Y.Z.
|
||||
|
||||
When vX.Y.Z is later released, the same NEWS-worthy item will also be
|
||||
included in the vX.Y.Z section and be denoted as:
|
||||
|
||||
(** also appeared: A.B.C) -- indicating that this item was previously
|
||||
included in release version vA.B.C.

- Updated shared library versioning scheme and linking style of MPI
|

applications. ABI has been broken from the v1.4 series; see the
|
||||
applications. The MPI application ABI has been broken from the
|
||||
v1.3/v1.4 series. MPI applications compiled against any prior
|
||||
version of Open MPI will need to, at a minimum, re-link. See the
|
||||
README file for more details.
|
||||
- Made the openib BTL safer if extremely low SRQ settings are used.
|
||||
- Fixed handling of the array_of_argv parameter in the Fortran
|
||||
binding of MPI_COMM_SPAWN_MULTIPLE (** also to appear: 1.4.3).
|
||||
- Fixed mallox(0) warnings in some collectives.
|
||||
- Fixed a problem with the Fortran binding for
|
||||
MPI_FILE_CREATE_ERRHANDLER. Thanks to Secretan Yves for identifying
|
||||
the issue (** also to appear: 1.4.3).
|

- Updates to the LSF PLM to ensure that the path is correctly passed.
|

Thanks to Teng Lin for the patch (** also to appear: 1.4.3).
|
||||
- Fixes for the F90 MPI_COMM_SET_ERRHANDLER and MPI_WIN_SET_ERRHANDLER
|
||||
bindings. Thanks to Paul Kapinos for pointing out the issue
|
||||
(** also to appear: 1.4.3).
|
||||
- Fixes for Solaris oversubscription detection.
|
||||
- If the PML determines it can't reach a peer process, print a
|
||||
slightly more helpful message. Thanks to Nick Edmonds for the
|
||||
suggestion.
|
||||
- Make btl_openib_if_include/exclude function the same what
|
||||
btl_tcp_if_include/exclude work (i.e., supplying an _include list
|
||||
overrides supplying an _exclude list).
|
||||
- Apply more scalable reachability algorithm on platforms with more
|
||||
than 8 TCP interfaces.
|
||||
- Various assembly code updates for more modern platforms / compilers.
|
||||
- Relax restrictions on using certain kinds of MPI datatypes with
|
||||
one-sided operations. Users beware; not all MPI datatypes are valid
|
||||
for use with one-sided operations!
|
||||
- Improve behavior of MPI_COMM_SPAWN with regards to --bynode.
|
||||
- Various threading fixes in the openib BTL and other core pieces of
|
||||
Open MPI.
|
||||
- Various help file and man pages updates.
|
||||
- Various FreeBSD and NetBSD updates and fixes. Thanks to Kevin
|
||||
Buckley and Aleksej Saushev for their work.
|
||||
- Fix case where freeing communicators in MPI_FINALIZE could cause
|
||||
process failures.
|
||||
- Print warnings if shared memory state files are opened on what look
|
||||
like networked filesystems.
|
||||
- Update libevent to v1.4.13.
|
||||
- Allow propagating signals to processes that call fork().
|
||||
- Fix bug where MPI_GATHER was sometimes incorrectly examining the
|
||||
datatype on non-root processes. Thanks to Michael Hofmann for
|
||||
investigating the issue.
|
||||
- Various Microsoft Windows fixes.
|
||||
- Various Catamount fixes.
|
||||
- Various checkpoint / restart fixes.
|
||||
- Xgrid support has been removed until it can be fixed (patches
|
||||
would be welcome).
|
||||
- Added simplistic "libompitrace" contrib package. Using the MPI
|
||||
profiling interface, it essentially prints out to stderr when select
|
||||
MPI functions are invoked.
|
||||
- Update bundled VampirTrace to v5.8.2.
|
||||
- Add pkg-config(1) configuration files for ompi, ompi-c, ompi-cxx,
|
||||
ompi-f77, ompi-f90. See the README for more details.
|
||||
- Added "knem" support (direct process-to-process copying for shared

memory message passing). See http://runtime.bordeaux.inria.fr/knem/
