hwloc component weren't reverse applied to the external hwloc
component. Additionaly, if we add stuff to LDFLAGS/LIBS, we also may
need to append (DY)LD_LIBRARY_PATH (here in this configure process
only), otherwise future configure tests may fail because they can't
find libhwloc.so (e.g., if you --with-hwloc=/some/path, we need to add
/some/path/lib to (DY)LD_LIBRARY_PATH).

2. binding supported, but not bound - the bitset returned by get_cpubind is the same as the available cpuset
3. binding supported and bound - bitset from get_cpubind is a subset of available cpuset
4. only one cpu is available - in this case, get_cpubind matches the available cpuset, but we are effectively bound

https://svn.open-mpi.org/trac/ompi/wiki/ProcessPlacement
The wiki page is incomplete at the moment, but I hope to complete it over the next few days. I will provide updates on the devel list. As the wiki page states, the default and most commonly used options remain unchanged (except as noted below). New, esoteric and complex options have been added, but unless you are a true masochist, you are unlikely to use many of them beyond perhaps an initial curiosity-motivated experimentation.
In a nutshell, this commit revamps the map/rank/bind procedure to take into account topology info on the compute nodes. I have, for the most part, preserved the default behaviors, with three notable exceptions:
1. I have at long last bowed my head in submission to the system admin's of managed clusters. For years, they have complained about our default of allowing users to oversubscribe nodes - i.e., to run more processes on a node than allocated slots. Accordingly, I have modified the default behavior: if you are running off of hostfile/dash-host allocated nodes, then the default is to allow oversubscription. If you are running off of RM-allocated nodes, then the default is to NOT allow oversubscription. Flags to override these behaviors are provided, so this only affects the default behavior.
2. both cpus/rank and stride have been removed. The latter was demanded by those who didn't understand the purpose behind it - and I agreed as the users who requested it are no longer using it. The former was removed temporarily pending implementation.
3. vm launch is now the sole method for starting OMPI. It was just too darned hard to maintain multiple launch procedures - maybe someday, provided someone can demonstrate a reason to do so.
As Jeff stated, it is impossible to fully test a change of this size. I have tested it on Linux and Mac, covering all the default and simple options, singletons, and comm_spawn. That said, I'm sure others will find problems, so I'll be watching MTT results until this stabilizes.

I am making a final decision to decide the behavior of what happens
when an MCA parameter is re-registered and changes types. In
developer builds (i.e., OPAL_ENABLE_DEBUG==1), a show_help message
will be displayed. In all builds, an error status will be returned.
Specifically, the logic looks like this:
{{{
if (detect_re-registration_with_type_change) {
#if OPAL_ENABLE_DEBUG
opal_show_help(...);
#endif
return OPAL_ERR_VALUE_OUT_OF_BOUNDS;
}
}}}
If someone would like to change this behavior, they are welcome to do
so. :-) I am committing this so that ''some'' action occurs (rather
than talking about the issue and then nothing happens).
This commit was SVN r25432.
handled properly when MCA parameters are re-registered and their types
change. Specifically, this case was broken:
1. Register an int MCA param with a non-zero default value
1. Re-register the same MCA param as a string with a NULL default value
The 2nd step would cause a segv because the first int default value
wasn't being reset properly. Here's sample code that shows the issue:
{{{
{
int ibogus;
char *sbogus;
opal_init(&argc, &argv);
mca_base_param_reg_int_name("type", "name", "help", false, false, 3, &ibogus);
printf("Ibogus: %d\n", ibogus);
mca_base_param_reg_string_name("type", "name", "help", false, false, NULL, &sbogus);
printf("Sbogus: %s\n", (NULL == sbogus) ? "NULL" : sbogus);
exit(0);
}
}}}
This commit fixes the problem from the sample code above as well as
the a similar issue for file-set MCA params and override values. It
also resets default values for MCA params initially registered as a
string but then re-registered as an int.
This commit was SVN r25392.
Use hwloc to obtain the cpuset for each process during mpi_init, and share that info in the modex. As it arrives, use a new opal_hwloc_base utility function to parse the value against the local proc's cpuset and determine where they overlap. Cache the value in the pmap object as it may be referenced multiple times.
Thus, the return value from orte_ess.proc_get_locality is a 16-bit bitmask that describes the resources being shared with you. This bitmask can be tested using the macros in opal/mca/paffinity/paffinity.h
Locality is available for all procs, whether launched via mpirun or directly with an external launcher such as slurm or aprun.

if so, use it for bit-operations like opal_cube_dim and opal_hibit.
Implement two versions of power-of-two.
In case of opal_next_poweroftwo, this reduces the average execution
time from 83 cycles to 4 cycles (Intel Nehalem, icc, -O2, inlining,
measured rdtsc, with loop over 2^27 values).
Numbers for other functions are similar (but of course heavily depend
on the usage, e.g. opal_hibit() with a start of 4 does not save
much). The bsr instruction on AMD Opteron is also not as fast.
- Replace various places where the next power-of-two is computed.

Since hwloc has a dynamic bitmap size, it could actually have bits set
that will not fit in the paffinity mask. We already made sure that we
didn't overrun the paffinity mask; now also set the return value to
OPAL_ERR_VALUE_OUT_OF_BOUNDS (wow, we really thought of everything
with those error codes, eh?) if the hwloc bitmap has bits set higher
than what will fit into the paffinity bitmask.

these MCA parameters were never on a release branch, I'm just
moving/renaming them outright and not leaving aliases to the old

Note that some upper layer needs to call
opal_hwloc_base_set_process_membind_policy() to set the
set-by-MCA-param process-wide memory affinity policy. We can't do
this automatically during hwloc_base_open() because, for reasons
described elsewhere, opal_hwloc_topology is not automatically filled
during hwloc_base_open() (in short: potential scalability issues when
launching many MPI processes simultaneously on a single machine, for
example).

This commit does a few things:
* Introduce a new OPAL MCA base function:
mca_base_param_check_exclusive_string(). It checks to see that the
''user'' does not set two MCA parameters that are mutually
exclusive by checking the source of those MCS param values.
* Use the above function in many BTLs (and the OOB TCP) to ensure
that <foo>_if_include and <foo>_if_exclude are not both specified
''by the user''.
* Re-arrange many of these BTLs to move their MCA registration code
into a separate component_register() function (vs. the
component_open() function).

It was agreed that opal_init_util had wound up being used in unintended ways, which raised the problem of getting reference counts to work right. However, fixing it would involve more pain than it was worth - and so long as the other layers are made to behave similarly, I have no preference either way.
Complete implementation will follow - for now, this just reverts the prior changes.
