as Interlagos, Valencia, or other Bulldozer-based chips).</p></li>
<li><p>New MCA parameters to control process-wide memory binding policy:
hwloc_base_mem_alloc_policy, hwloc_base_mem_bind_failure_action (see
<code class="docutils literal notranslate"><span class="pre">ompi_info</span> <span class="pre">--param</span> <span class="pre">hwloc</span> <span class="pre">base</span></code>).</p></li>

<li><p>Fix the type of the C++ constant MPI::IN_PLACE.</p></li>
<li><p>Various enhancements to the openib BTL:</p>
<blockquote>
<div><ul class="simple">
<li><p>Added <code class="docutils literal notranslate"><span class="pre">btl_openib_if_[in|ex]clude</span></code> MCA parameters for
including/excluding comma-delimited lists of HCAs and ports.</p></li>
<li><p>Added RDMA CM support, includng <code class="docutils literal notranslate"><span class="pre">btl_openib_cpc_[in|ex]clude</span></code>
MCA parameters</p></li>
<li><p>Added NUMA support to only use “near” network adapters</p></li>
<li><p>Added “Bucket SRQ” (BSRQ) support to better utilize registered
memory, including btl_openib_receive_queues MCA parameter</p></li>
<li><p>Added ConnectX XRC support (and integrated with BSRQ)</p></li>
<li><p>Added btl_openib_ib_max_inline_data MCA parameter</p></li>
<li><p>Added iWARP support</p></li>
<li><p>Revamped flow control mechansisms to be more efficient</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">mpi_leave_pinned=1</span></code> is now the default when possible,
automatically improving performance for large messages when
application buffers are re-used</p></li>
</ul>
</div></blockquote>
</li>
<li><p>Elimiated duplicated error messages when multiple MPI processes fail
with the same error.</p></li>
<li><p>Added NUMA support to the shared memory BTL.</p></li>
<li><p>Add Valgrind-based memory checking for MPI-semantic checks.</p></li>
<li><p>Add support for some optional Fortran datatypes (MPI_LOGICAL1,
MPI_LOGICAL2, MPI_LOGICAL4 and MPI_LOGICAL8).</p></li>
<li><p>Remove the use of the STL from the C++ bindings.</p></li>
<li><p>Added support for Platform/LSF job launchers. Must be Platform LSF
v7.0.2 or later.</p></li>
<li><p>Updated ROMIO with the version from MPICH2 1.0.7.</p></li>
<li><p>Added RDMA capable one-sided component (called rdma), which
can be used with BTL components that expose a full one-sided
interface.</p></li>
<li><p>Added the optional datatype MPI_REAL2. As this is added to the “end of”
predefined datatypes in the fortran header files, there will not be
any compatibility issues.</p></li>
<li><p>Added Portable Linux Processor Affinity (PLPA) for Linux.</p></li>
<li><p>Addition of a finer symbols export control via the visibiliy feature
offered by some compilers.</p></li>
<li><p>Added checkpoint/restart process fault tolerance support. Initially
support a LAM/MPI-like protocol.</p></li>
<li><p>Removed “mvapi” BTL; all InfiniBand support now uses the OpenFabrics
driver stacks (“openib” BTL).</p></li>
<li><p>Added more stringent MPI API parameter checking to help user-level
debugging.</p></li>
<li><p>The ptmalloc2 memory manager component is now by default built as
a standalone library named libopenmpi-malloc. Users wanting to
use leave_pinned with ptmalloc2 will now need to link the library
into their application explicitly. All other users will use the
libc-provided allocator instead of Open MPI’s ptmalloc2. This change
may be overriden with the configure option enable-ptmalloc2-internal</p></li>
<li><p>The leave_pinned options will now default to using mallopt on
Linux in the cases where ptmalloc2 was not linked in. mallopt
will also only be available if munmap can be intercepted (the
default whenever Open MPI is not compiled with <code class="docutils literal notranslate"><span class="pre">--without-memory-manager</span></code>.</p></li>
<li><p>Open MPI will now complain and refuse to use leave_pinned if
no memory intercept / mallopt option is available.</p></li>
<li><p>Add option of using Perl-based wrapper compilers instead of the
C-based wrapper compilers. The Perl-based version does not
have the features of the C-based version, but does work better
in cross-compile environments.</p></li>

<li><p>Fixed residual .TRUE. issue with copying MPI attributes set from
Fortran.</p></li>
<li><p>Remove unnecessary logic from Solaris pty I/O forwarding. Thanks to
Francoise Roch for bringing this to our attention.</p></li>
<li><p>Fixed error when count = 0 was given for multiple completion MPI
functions (MPI_TESTSOME, MPI_TESTANY, MPI_TESTALL, MPI_WAITSOME,
MPI_WAITANY, MPI_WAITALL).</p></li>
<li><p>Better handling in MPI_ABORT for when peer processes have already
died, especially under some resource managers.</p></li>
<li><p>Random updates to README file, to include notes about the Portland
compilers.</p></li>
<li><p>Random, small threading fixes to prevent deadlock.</p></li>
<li><p>Fixed a problem with handling long mpirun app files. Thanks to Ravi
Manumachu for identifying the problem.</p></li>
<li><p>Fix handling of strings in several of the Fortran 77 bindings.</p></li>
<li><p>Fix LinuxPPC assembly issues. Thanks to Julian Seward for reporting
the problem.</p></li>
<li><p>Enable pty support for standard I/O forwarding on platforms that
have ptys but do not have openpty(). Thanks to Pierre Valiron for
bringing this to our attention.</p></li>
<li><p>Disable inline assembly for PGI compilers to avoid compiler errors.
Thanks to Troy Telford for bringing this to our attention.</p></li>
<li><p>Added MPI_UNSIGNED_CHAR and MPI_SIGNED_CHAR to the allowed reduction

Solaris. Thanks to Pierre Valiron for reporting the issue.</p></li>
<li><p>Added MPI_BOOL to the intrinsic reduction operations MPI_LAND,

on multi-NIC nodes, a NIC could get paired with a NIC on another
network (typically resulting in deadlock). Thanks to Ken Mighell
for pointing this out to us.</p></li>
<li><p>Change the behavior of orterun (mpirun, mpirexec) to search for
argv[0] and the cwd on the target node (i.e., the node where the
executable will be running in all systems except BProc, where the
searches are run on the node where orterun is invoked).</p></li>

crashes on machines with weak memory consistency models (including
POWER/PowerPC machines).</p></li>

killed by a signal. The exit status is now set to signo + 128, which
conforms with the behavior of (almost) all shells.</p></li>
<li><p>Correct a datatype problem with the convertor when partially
unpacking data. Now we can position the convertor to any position
not only on the predefined types boundaries. Thanks to Yvan Fournier
for reporting this to us.</p></li>

ability to background mpirun and a loss of data issue when

rsh startup. Thanks to Glen Morris for finding these typos.</p></li>
<li><p>Fixed missing constants in MPI C++ bindings.</p></li>
<li><p>Fixed some errors caused by threading issues.</p></li>
<li><p>Fixed openib BTL flow control logic to not overrun the number of
send wqes available.</p></li>
<li><p>Update to match newest OpenIB user-level library API. Thanks to

BTL.</p></li>
<li><p>Reduce memory footprint of openib BTL.</p></li>

Gottbrath for supplying the fix.</p></li>
<li><p>Fix Darwin net/if.h configure warning.</p></li>
<li><p>The GNU assembler unbelievably defaults to making stacks executable.
So when using gas, add flags to explicitly tell it to not make
stacks executable (lame but necessary).</p></li>
<li><p>Add missing MPI::Request::Get_status() methods. Thanks to Bill
Saphir for pointing this out to us.</p></li>
<li><p>Improved error messages on memory registration errors (e.g., when
using high-speed networks).</p></li>
<li><p>Open IB support now checks firmware for how many outstanding RDMA
requests are supported. Thanks to Mellanox for pointing this out to
us.</p></li>
<li><p>Enable printing of stack traces in MPI processes upon SIGBUS,
SIGSEGV, and SIGFPE if the platform supports it.</p></li>
<li><p>Fixed F90 compilation support for the Lahey compiler.</p></li>
