- Add signal handler BLCR register (helps with debugging)
- ifdef out the cr_request_file section for checkpointing self.
There is a bug with the 0.4.2 version of BLCR such that this
does not handle moving checkpoint files around.
I'm following up with the BLCR folks on this one (and checking
the newest release).
This commit was SVN r14069.
This merge adds Checkpoint/Restart support to Open MPI. The initial
frameworks and components support a LAM/MPI-like implementation.
This commit follows the risk assessment presented to the Open MPI core
development group on Feb. 22, 2007.
This commit closes trac:158
More details to follow.

* On 10.4.8 (and possibly others), siginfo is NULL in the signal
callback on 64 bit Intel builds, so account for that in the signal
callback.

This saves some memory for the constructors and destructors arrays of a
class by counting the constructors and destructors while we are counting
the cls_depth. And the reversion of the constructor array can now be done
without an extra loop.

allocated from mpool memory (which is registered memory for RDMA transports)
This is not a problem for a small jobs, but for a big number of ranks an
amount of waisted memory is big.
This commit was SVN r13921.
- mca_base_param_file_prefix
(Default: NULL)
This is the fullname of the "-am" mpirun option. Used to specify a ':'
separated list of AMCA parameter set files.
- mca_base_param_file_path
(Default: $SYSCONFDIR/amca-param-sets/:$CWD)
The path to search for AMCA files with relative paths. A warning will be
printed if the AMCA file cannot be found.
* Added a new function "mca_base_param_recache_files" the re-reads the file
configurations. This is used internally to help bootstrap the MCA system.
* Added a new orterun/mpirun command line option '-am' that aliases for the
mca_base_param_file_prefix MCA parameter
* Exposed the opal_path_access function as it is generally useful in other
places in the code.
* New function "opal_cmd_line_make_opt_mca" which will allow you to append a
new command line option with MCA parameter identifiers to set at the same
time. Previously this could only be done at command line declaration time.
* Added a new directory under the $pkgdatadir named "amca-param-sets" where all
the 'shipped with' Open MPI AMCA parameter sets are placed. This is the first
place to search for AMCA sets with relative paths.
* An example.conf AMCA parameter set file is located in
contrib/amca-param-sets/.
* Jeff Squyres contributed an OpenIB AMCA set for benchmarking.
Note: You will need to autogen with this commit as it adds a configure param.
Sorry :(
This commit was SVN r13867.
the dispatch function opal_atomic_cmpset_acq_xx was used to call
opal_atomic_cmpset_acq_32 would cause the compiler / linker to fix up a
jump address to be itself, leading to an infinite loop.
We're still looking into exactly what caused this, but during the
investigation into the hang, we determined that the compiler (both pathcc
and gcc) weren't always inlining both the call to opal_atomic_cmpset_acq_xx
and opal_atomic_cmpset_acq_32, meaning there was a function call in
opal_atomic_lock. The atomic lock will always be 32 bit, so there's no
need for the dispatch function, so might as well remove the dispatch
function that may or may not be inlined.
A bug fix that leads to potentially better performance. Gotta love the
few times that happens...

to flush all writes pending (ie, the data being protected) out of the memory
manager before we write the spinlock unlock. Only need a wmb instead of
full mb, which is at least slightly less intrusive. Also, after much
thought, no need for a memory barrier in init.

- Set ompi-specific autoconf cache-variables
- Implement one function to check for availability of an
attribute with the possibility for a cross-check.
- Do cross-checks for
__attribute__(format)
__attribute__(nonnull)
__attribute__(sentinel)
__attribute__(warn_unused_result)
- Grep the compilers warnings for keywords regarding ignored
attributes.
- Include also the no_instrument_function
This commit was SVN r13556.
Add new function opal_get_num_processors() that will return the number
of processors on the local host. Does the Right thing in POSIX
environments (to include a special case for OS X), and will shortly do
the Right Thing for Windows (this commit includes a change to
configure, so I wanted to get that in before the US workday -- the
Windows code can some shortly because it won't involve configury
changes).
