This code effectively already exists in a few places in the code base;
this is mainly a consolidation.

variable was set, it was prefixed to ''all'' values in the wrapper
compiler data text files. For example, if OPAL_DESTDIR was set to
/tmp/bogus and a wrapper compiler data file contained the line:
preprocessor_flags=-pthread
The value would be exanded to:
/tmp/bogus/-pthread
Which is clearly wrong. After some back-and-forth with Ralph and
Brian, Brian submitted this patch that fixes the problem. Now we
handle three cases properly (assume that configure was invoked with
--prefix=/opt/openmpi and no other directory specifications, and
$OPAL_DESTDIR is set to /tmp/buildroot):
1. Individual directories, such as libdir. These need to be prepended
with DESTDIR. I.e., return /tmp/buildroot/opt/openmpi/lib.
2. Compiler flags that have ${FIELD} values embedded in them. For
example, consider if a wrapper compiler data file contains the
line:
preprocessor_flags=-DMYFLAG="${prefix}/share/randomthingy/"
The value we should return is:
-DMYFLAG="/tmp/buildroot/opt/openmpi/share/randomthingy/"
3. Compiler flags that do not have any ${FIELD} values. For example,
consider if a wrapper compiler data file contains the line:
preprocessor_flags=-pthread
The value we should return is:
-pthread
Note, too, that this OPAL_DESTDIR futzing only needs to occur during
opal_init(). By the time opal_init() has completed, all values should
be substituted in that need substituting. Hence, we take an extra
parameter (is_setup) to know whether we should do this futzing or
not.

#define CACHE_LINE_SIZE to 128. This name has a conflict on NetBSD,
and it seems kinda odd to have a header file that ''only'' defines a
single value. Also, we'll soon be raising hwloc to be a first-class
item, so having this file around seemed kinda weird.
Therefore, I replaced CACHE_LINE_SIZE with opal_cache_line_size, an
int (in opal/runtime/opal_init.c and opal/runtime/opal.h) on the
rationale that we can fill this in at runtime with hwloc info (trunk
and v1.5/beyond, only). The only place we ''needed'' a compile-time
CACHE_LINE_SIZE was in the BTL SM (for struct padding), so I made a
new BTL_SM_ preprocessor macro with the old CACHE_LINE_SIZE value
(128). That use isn't suitable for run-time hwloc information,
anyway.

* Remove OPAL_ERR_PAFFINITY_NOT_SUPPORTED; fit it into the generic
OPAL_ERR_NOT_SUPPORTED case.
* When odls_default detects that processor affinity is not supported,
it prints a specific message about it, and then it suppressed a
generic HNP help message that would normally follow it (i.e., it's
easier to have the "processor affinity is not supported" show_help
message last).
* Use some symbolic names in odls_default instead of fixed int's,
just for slight readability improvements in the code.
* Introduce orte_show_help_suppress(), which gives the ability to
suppress any future showings of any arbitrary show_help() message.
This is useful if you display message X and want to suppress
message Y. This suppression *only* works in environments where
orte_show_help() does coalescing.

This commit was SVN r23218.
* If < 0, it's an OPAL_ERR_* value
* If >= 0, it's the actual output value of the function
This is problematic for the OPAL_SOS stuff. This commit changes those
functions to always return OPAL_* statuses and send the output value
back through output parameters (like 95% of the rest of the code
base). This avoids the confusion with OPAL_SOS stuff and makes
paffinity work again (e.g., mpirun --bind-to-core ...).
I updated all paffinitiy modules for the new function signatures, and
bumped the paffinity API version up to 2.0.1. I don't think the
version change will matter, though, because we'll be introducing
support for hardware threads soon, which will either bump the
paffinity version again or we'll replace paffinity with
a new framework.
This commit was SVN r23197.
The fix is to just check if the return value is positive or not, since all the SOS encoded errors are *always* negative.
The real fix (as Ralph points out) is to change these functions (opal_pointer_array_add and mca_base_param*) to return the index as a pointer.

(OMPI_ERR_* = OPAL_SOS_GET_ERR_CODE(ret)), since the return value could be a
SOS-encoded error. The OPAL_SOS_GET_ERR_CODE() takes in a SOS error and returns
back the native error code.
* Since OPAL_SUCCESS is preserved by SOS, also change all calls of the form
(OPAL_ERROR == ret) to (OPAL_SUCCESS != ret). We thus avoid having to
decode 'ret' to get the native error code.
This commit was SVN r23162.
The OPAL SOS framework tries to meet the following objectives:
* reduce the cascading error messages and the amount of code needed to print an error message.
* build and aggregate stacks of encountered errors and associate related individual errors with each other.
* allow registration of custom callbacks to intercept error events.

I forgot to mention one more thing in the r23152 commit message:
* Copy the fix for hwloc's m4 to disable the configure flag
--enable-debug when building in embedding mode, because it can be
hijacked by the outter-level application. In this case, if you
configured OMPI with --enable-debug (or have --enable-debug in a
platform file), you'd see all of hwloc's debug output. Ick. hwloc
1.0 will include this fix.

supports a wide variety of operating systems and platforms; see the
opal/mca/paffinity/hwloc/hwloc/README file for details.
This component includes an embedded copy of hwloc, currently based on
hwloc-1.0rc6. But note that hwloc is properly SVN imported into the
/vendor branch, so it will be easy to update when 1.0 GA is released.
Note that the hwloc tree embedded in opal/mca/paffinity/hwloc/hwloc is
identical to a hwloc distribution tarball, except that much of the
documentation was rm -rf'ed (because we don't need it for the embedded
case).
Since the paffinity framework currently does not understand hardware
threads, the hwloc component compensates for this by identifying cores
by the "first" hardware thread on that core. Hopefully we'll update
paffinity someday to understand hardware threads. :-)
configure grew a --with-hwloc option, analogous to what we do for many
other external libraries that OMPI supports. However, there's a new
feature: due to the request of several distros, OMPI can be configured
to build with its internal copy of hwloc or with an external copy of
hwloc (e.g., a system-installed hwloc).
1. If --with-hwloc is not specified, Open MPI will try to use its
internal copy (but silently fail/ignore hwloc if that fails).
1. If --with-hwloc=<dir> is supplied, Open MPI looks for hwloc
support in <dir> (and --with-hwloc-libdir=<dir>, if specified).
1. If --with-hwloc=external is supplied, Open MPI will look for hwloc
in a compiler/linker default external location.
1. If --with-hwloc=internal is supplied, Open MPI will use its
internal copy of hwloc.
Some of OMPI's main configury had to be slightly re-arranged in the
bootstrapping phase to accomodate hwloc's configry needs.

* Remove the ptmalloc memory component; replace it with a new "linux"
memory component.
* The linux memory component will conditionally compile in support
for ummunotify. At run-time, if it has ummunotify support and
finds run-time support for ummunotify (i.e., /dev/ummunotify), it
uses it. If not, it tries to use ptmalloc via the glibc memory
hooks.
* Add some more API functions to the memory framework to accomodate
the ummunotify model (i.e., poll to see if memory has "changed").
* Add appropriate calls in the rcache to the new memory APIs to see
if memory has changed, and to react accordingly.
* Add a few comments in the openib BTL to indicate why we don't need
to notify the OPAL memory framework about specific instances of
registered memory.
* Add dummy API calls in the solaris malloc component (since it
doesn't have polling/"did memory change" support).

done this way a long time ago for the "gee whiz!" factor -- when in
reality, they really only need one-of-many-run-time priority
selection).
Changed run-time priorities to be as follows:
* darwin: 20
* linux: 20
* posix: 10
* solaris: 30
* test: 5
* windows: 20
I have a very dim (possibly untrue) recollection that Solaris needs to
have a higher priority than others just to ensure that no other is
chosen under Solaris. Make all other "native" components have a
priority of 20 (they shouldn't conflict with each other). Make the
posix fallback component have a priority of 10. Make the test
component priority 5, meaning someone can always select it, but you
can also make a "never select me" component that prioritizes itself
under test.

the maximum possible number of cpus rather than just the number of cpus

holes, such as on ppc64 with smt off (as discussed in #2365).
