Sorry for configure changes during the day; I totally forgot about
that. :-(

The top-level OMPI configure script already checks for "restrict" and
will issue a #define for it. PAC_C_RESTRICT would also check for
restrict, but sometimes come up with a different answer than the
top-level OMPI configure script, thereby resulting in conflicting
#define's for "restrict" (e.g., icc 9.0/9.1 on linux x86-64).
So it's easiest just to remove this test from ROMIO's configure.in
script.
This commit was SVN r14286.
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.

Ticket 590 --> https://svn.open-mpi.org/trac/ompi/ticket/590
* Create a new request type: NOOP (described below)
* For all MPI_*_INIT functions, OBJ_NEW an ompi_request_t and set its
type to NOOP
* Ensure that the NOOP requests are OBJ_RELEASE'd when they are done
* MPI_START looks at the request type; if NOOP, just return success. If
not, call the PML start() function
* MPI_STARTALL always pass the entire array of requests back to the PML
(see next point)
* Make the PMLs only process PML requests (i.e., ignore/skip anything
that isn't of type PML -- such as the NOOP requests)
* Add a little more param error checking in STARTALL

trying to run make in the romio directory without any Makefiles. This
really only happens on the targets that recurse into DIST_SUBDIRS - ie

explicitly enabled at run-time with the mca parameter
io_romio_enable_parallel_optimizations set to something non-zero.
This will enable some magic flags in Panasas if the user didn't
set them (either on or off) and do some slightly better things
with strided collective writes.

things I found:
- Locking should prevent it from happening (I think), but there was a
race condition in the component progress -- a callback could be
triggered that would free the request before it was off the outstanding
requests list.
- When pulling a request off the component free list, make sure to
reinitialize the free_called state on the IO request. This was
what was causing Edgar's failures
- In the request cleanup code, pull the request out of the per-
component free list before returning to the free list. This
probably would cause asserts to fire, although it looks like
I wrote the loops such that it would have been memory safe if
the asserts didn't fire. Not really sure why I did that, but
let's try it again...
This should go to the v1.0 and v1.1 branches.
This commit was SVN r9913.
- We had a bad conditional choice, such that asking for pvfs2 would
result in pvfs trying to build as well, which was going to fail.
- We didn't try to link in the libray for PVFS2's adio component.
- We were clobbering romio_flags, so it was impossible to pass
flags to romio (like the selection of filesystems)
This commit was SVN r9854.
- LDFLAGS set at the top level of Open MPI were not passed to the
ROMIO configure script
- If ROMIO was explicitly required (with --enable-io-romio) and
not able to be built, abort OMPI's configure script.
This needs to go to the v1.0 and v1.1 branches.

to let the PML (or io, more generally the low level request manager)
to have it's own release function (what was before the req_fini). This
function will only be called from the low level while the req_free will
be called from the upper level (MPI layer) in order to mark the request
as not used by the user anymore.
From the request point of view the requests will be marked as inactive
everytime we read their status (true for persistent as well). As
MPI_REQUEST_NULL is already marked as inactive, the test and wait functions
are simpler. The drawback is that now we have to change in the
ompi_request_{test|wait} the req_status of the request once we get it's
status.

as needed for the modified source tree layout. Since we don't include
anything but mpi.h in the ROMIO build, we don't need most of the flags
anyway...
This commit was SVN r8995.
- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)
This commit was SVN r8985.
- fall back to compile test for windows paffinity component
when cross compiling
- fall back to platform guess when checking for threads having
different pids with pthreads (yes on linux, no elsewhere)
- pass the proper host, target, and build flags to the
ROMIO configure script
With these changes, cross-compiling should be possible with the exception
of the Fortran 77 and Fortran 90 bindings. Fortran 77 can be cross-
compiled if cache values are provided for type sizes and alignment.

the script did not complete successfully
- ROMIO likes to default to using the system compiler if no compiler is
specified. This can lead to using a different compiler for ROMIO as
for Open MPI, which is not always a good thing. Reset the default to
behave the same way Open MPI does.

functionality. This is a global registration, so all components have to be made
aware of the registration -- therefore, do things at the component level, not the
module level.
