A few changes were required to support this move:
1. the PMI component used to identify rte-related data (e.g., host name, bind level) and package them as a unit to reduce the number of PMI keys. This code was moved up to the ORTE layer as the OPAL layer has no understanding of these concepts. In addition, the component locally stored data based on process jobid/vpid - this could no longer be supported (see below for the solution).
2. the hash component was updated to use the new opal_identifier_t instead of orte_process_name_t as its index for storing data in the hash tables. Previously, we did a hash on the vpid and stored the data in a 32-bit hash table. In the revised system, we don't see a separate "vpid" field - we only have a 64-bit opaque value. The orte_process_name_t hash turned out to do nothing useful, so we now store the data in a 64-bit hash table. Preliminary tests didn't show any identifiable change in behavior or performance, but we'll have to see if a move back to the 32-bit table is required at some later time.
3. the db framework was a "select one" system. However, since the PMI component could no longer use its internal storage system, the framework has now been changed to a "select many" mode of operation. This allows the hash component to handle all internal storage, while the PMI component only handles pushing/pulling things from the PMI system. This was something we had planned for some time - when fetching data, we first check internal storage to see if we already have it, and then automatically go to the global system to look for it if we don't. Accordingly, the framework was provided with a custom query function used during "select" that lets you seperately specify the "store" and "fetch" ordering.
4. the ORTE grpcomm and ess/pmi components, and the nidmap code, were updated to work with the new db framework and to specify internal/global storage options.
No changes were made to the MPI layer, except for modifying the ORTE component of the OMPI/rte framework to support the new db framework.

So (finally) consolidate these two fields into one "slots" field. Add a field in orte_job_t to indicate when all the procs for a job will be launched together, so that staged operations can know when MPI operations are allowed.
This commit was SVN r27239.
For those nodes (and *only* those nodes) where the user does *not* specify a slot count, we will set the number of slots according to their direction: either to the number of cores, numas, sockets, or hwthreads. Otherwise, the slot count is set to 1.
Note that the default behavior remains unchanged: in the absence of any value for #slots, and in the absence of any directive to set #slots, we will set #slots=1.
This commit was SVN r27236.
Remove some stale configure.m4's we no longer need.
Optimize the nidmaps a bit by only sending info that has changed each time, instead of sending a complete copy of everything. Makes no difference for the typical MPI job - only impacts things like staged execution where we are sending multiple (possibly many) launch messages.
This commit was SVN r27165.
Update all the orte ess components to remove their associated APIs for retrieving proc data. Update the grpcomm API to reflect transfer of set/get modex info to the db framework.
Note that this doesn't recreate the old GPR. This is strictly a local db storage that may (at some point) obtain any missing data from the local daemon as part of an async methodology. The framework allows us to experiment with such methods without perturbing the default one.

Brian dealt with this in the past by creating platform files and using "no-build" to block the components. This was clunky, but acceptable when only one organization was using that option. However, that number has now expanded to at least two more locations.
Accordingly, make --without-rte-support actually work by adding appropriate configury to prevent components from building when they shouldn't. While doing so, remove two frameworks (db and rmcast) that are no longer used as ORCM comes to a close (besides, they belonged in ORCM now anyway). Do some minor cleanups along the way.

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.
This commit was SVN r25476.
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.

Over the course of time, usage of static ports got corrupted in several places, the "parent" info got incorrectly reset, etc. So correct all that and get the regex-based wireup going again.
Also, don't pass node lists if static ports aren't enabled - they are of no value to the orted and just create the possibility of overly-long cmd lines.

This means that the converters (opal_err2str, orte_err2str) can now
return NULL as a "silent error". The return value of opal_err2str_fn_t
is the status of the operation (OPAL_SUCCESS or OPAL_ERROR).
This fixes the "Unknown error" message issues on the trunk.
This commit was SVN r24371.
It is statically initialized to the real back-end OPAL show_help
function. During orte_show_help_init(), the variable is re-assigned
with the value of the back-end ORTE show_help function (the one that
does error message aggregation).
Therefore, anything that calls opal_show_help() after a certain point
in orte_init() will have their show_help messages be aggregated.
w00t! Even code down in OPAL -- that has no knowledge of ORTE -- will
have their messages aggregated. '''Double w00t!'''
During orte_show_help_finalize(), we restore the original pointer
value so that it something calls opal_show_help() after
orte_finalize(), it'll still work properly (but it won't be
aggregated).

This commit was SVN r23943.
This is a fairly intrusive change, but outside of the moving of opal/event to opal/mca/event, the only changes involved (a) changing all calls to opal_event functions to reflect the new framework instead, and (b) ensuring that all opal_event_t objects are properly constructed since they are now true opal_objects.
Note: Shiqing has just returned from vacation and has not yet had a chance to complete the Windows integration. Thus, this commit almost certainly breaks Windows support on the trunk. However, I want this to have a chance to soak for as long as possible before I become less available a week from today (going to be at a class for 5 days, and thus will only be sparingly available) so we can find and fix any problems.
Biggest change is moving the libevent code from opal/event to a new opal/mca/event framework. This was done to make it much easier to update libevent in the future. New versions can be inserted as a new component and tested in parallel with the current version until validated, then we can remove the earlier version if we so choose. This is a statically built framework ala installdirs, so only one component will build at a time. There is no selection logic - the sole compiled component simply loads its function pointers into the opal_event struct.
I have gone thru the code base and converted all the libevent calls I could find. However, I cannot compile nor test every environment. It is therefore quite likely that errors remain in the system. Please keep an eye open for two things:
1. compile-time errors: these will be obvious as calls to the old functions (e.g., opal_evtimer_new) must be replaced by the new framework APIs (e.g., opal_event.evtimer_new)
2. run-time errors: these will likely show up as segfaults due to missing constructors on opal_event_t objects. It appears that it became a typical practice for people to "init" an opal_event_t by simply using memset to zero it out. This will no longer work - you must either OBJ_NEW or OBJ_CONSTRUCT an opal_event_t. I tried to catch these cases, but may have missed some. Believe me, you'll know when you hit it.
There is also the issue of the new libevent "no recursion" behavior. As I described on a recent email, we will have to discuss this and figure out what, if anything, we need to do.

as orte_show_help(), but it takes a fully-rendered string instead of a
varargs list that must be rendered. This function is useful in cases
where one entity renders the "show help" string and a different entity
sends the string via the normal orte "show help" mechanisms for
aggregation, etc.
Example usage: errors occur in the ODLS after forking but before
exec'ing. In such cases, it makes sense for the the child process to
render the "show help" string because it has all the details about the
error. But the child process can't call orte_show_help() itself
because it is not an ORTE process -- it can't OOB send the message
to the HNP, etc.
After rendering the help string, the child sends the rendered string
to its parent via normal IPC (e.g., via a pipe) and the parent can
then invoke orte_show_help_norender() with the ready-to-go string.
The message then displays out via the normal mechanisms (i.e., out via
the HNP, aggregated/coalesced, etc.).

Also fixed debugger daemon cospawn, both for initial launch and attach-while-running modes. Tested and verified on rsh and slurm.

* 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 r23249.
(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.

1. file activity - can monitor file size, access and modification times. If these fail to change over a specified number of sampling iterations (rate is an mca param), then the errmgr is notified.
2. memory usage - checks amount of memory used by a process. Limit and sampling rate can be set.
This support must be enabled by configuring --enable-sensors.
ompi_info and orte-info have been updated to include the new framework.
Also includes some initial steps toward restoring the recovery capability. Most notably, the ODLS API has been extended to include a "restart_proc" entry for restarting a local process, and organizes the various ERRMGR framework globals into a single struct as we do in the other ORTE frameworks. Fix an oversight in the ERRMGR framework where a pointer array was constructed, but not initialized.
Implementation continues.
This commit was SVN r23043.
* add hnp and orted modules to the errmgr framework. The HNP module contains much of the code that was in the errmgr base since that code could only be executed by the HNP anyway.
* update the odls to report process states directly into the active errmgr module, thus removing the need to send messages looped back into the odls cmd processor. Let the active errmgr module decide what to do at various states.
* remove the code to track application state progress from the plm_base_launch_support.c code. Update the plm modules to call the errmgr directly when a launch fails.
* update the plm_base_receive.c code to call the errmgr with state updates from remote daemons
* update the routed modules to reflect that process state is updated in the errmgr
* ensure that the orted's open the errmgr and select their appropriate module
* add new pretty-print utilities to print process and job state. Move the pretty-print of time info to a globally-accessible place
* define a global orte_comm function to send messages from orted's to the HNP so that others can overlay the standard RML methods, if desired.
* update the orterun help output to reflect that the "term w/o sync" error message can result from three, not two, scenarios

Add a capability to parse the rankfile to extract node information in place of requiring both hostfile and rankfile for non-RM managed environments. The rankfile is -only- parsed for this IF the hostfile and -host options are not given. Otherwise, those are used to establish allocation info as we did before this commit.

Adds several new mpirun options:
* -bysocket - assign ranks on a node by socket. Effectively load balances the procs assigned to a node across the available sockets. Note that ranks can still be bound to a specific core within the socket, or to the entire socket - the mapping is independent of the binding.
* -bind-to-socket - bind each rank to all the cores on the socket to which they are assigned.
* -bind-to-core - currently the default behavior (maintained from prior default)
* -npersocket N - launch N procs for every socket on a node. Note that this implies we know how many sockets are on a node. Mpirun will determine its local values. These can be overridden by provided values, either via MCA param or in a hostfile
Similar features/options are provided at the board level for multi-board nodes.

orte_session_dir_finalize doesn't clean the right directories.
orte_session_dir_cleanup neither.
This patch fixes several issues:
1. orte_session_dir_cleanup():
1. when jobid is not a wildcard, jobid is used to build the job
session dir (instead of ORTE_LOCAL_JOBID).
1. ORTE_SUCCESS is unconditionally returned (instead of rc that
might have been previously set to another value).
1. orte_session_dir_finalize():
1. convert_jobid_to_string is not the right call to get the job
session dir.
1. in some places orte_process_info.top_session_dir is directly
used, without being prefixed with the base directory.
Factorized the code sections that build the job_session_dir into a
single orte_build_job_session_dir() function that is now called by
both orte_session_dir_finalize() and orte_session_dir_cleanup().

Update the various plm modules to enable it - just a minor change reflecting an added param to a plm base function.
Additional fixes included:
1. remove an erroneous cleanup of session directories in the tool finalize procedure - tools don't create session directories to begin with!
2. fix a duplicate free when attempting to execute a non-existent app
3. cleanup an typo in the comm utilities
4. fix comm_spawn - was perturbed by the changes in pack/unpack of orte_job_t to properly support orte-ps
Been tested on slurm and tm machines, using all tests in orte/test/mpi. May run into issue with command line length on large jobs due to inclusion of node info to support static ports - will fix this next with addition of regexp generator to compress that info.

This causes the orteds in the routing tree to remain alive until all termination "acks" from orteds below them have passed through. Thus, if we use static ports, we no longer require a direct orted-to-mpirun connection.
Also modify the binomial routed module so it conforms to what all the other routed modules do and have all messages pass along the routing tree instead of short-circuiting between orteds. This further reduces the number of ports being opened on backend nodes.

OMPI_* to OPAL_*. This allows opal layer to be used more independent
from the whole of ompi.

- Delete unnecessary header files using
contrib/check_unnecessary_headers.sh after applying
patches, that include headers, being "lost" due to
inclusion in one of the now deleted headers...
In total 817 files are touched.
In ompi/mpi/c/ header files are moved up into the actual c-file,
where necessary (these are the only additional #include),
otherwise it is only deletions of #include (apart from the above
additions required due to notifier...)
- To get different MCAs (OpenIB, TM, ALPS), an earlier version was
successfully compiled (yesterday) on:
Linux locally using intel-11, gcc-4.3.2 and gcc-SVN + warnings enabled
Smoky cluster (x86-64 running Linux) using PGI-8.0.2 + warnings enabled
Lens cluster (x86-64 running Linux) using Pathscale-3.2 + warnings enabled
This commit was SVN r21096.
several header files (previously included by header-files)
now have to be moved "upward".
This is mainly system headers such as string.h, stdio.h and for
networking, but also some orte headers.
This commit was SVN r21095.
We currently apply all of the MCA params in the parent job to the child. This commit allows a user to specify additional params for the child job, and to override any pre-existing params with the new value so they can better control behavior of the child job.
This commit was SVN r20989.
