Add orte configuration option to control the use of the framework in the system. Although the code will build, it will not be active unless configured with --enable-bootstrap.
If bootstrap is enabled and the new opal_sysinfo framework can successfully determine the cpu model, pass that info to the application as an MCA param to support some work at Sun.
Also, have daemons report back the resources they find to guide process mapping in bootstrap operations (i.e., where the daemon starts at node boot as opposed to being launched at application start).
Adjust some platform files to enable these capabilities.

The only sure way to kill the thing is with SIGKILL. After hours spent trying to debug this bizarre situation with a reliable reproducer, I finally tracked it down and fixed it.
Go figure...I sure can't.
This commit was SVN r22220.
Continue the reorganization of the configure system. Move files from the main config directory to their appropriate level-specific config directories. Modify the configure system to correctly handle compiler detection, test, and setup so that all things pertaining to opal and orte are done at the lower level, with the ompi configure system only looking at mpi-specific options.
Ensure the wrapper compilers for orte and ompi only get built when appropriate. Add support for c++ to the orte wrapper compilers, both script and non-script versions.

Wouldn't be so bad, except...the errmgr orders the termination of ALL procs, which kills any other job that should have been left alone.
Add a new proc and job state indicating "killed_by_cmd" so we can tell the difference between a proc/job that was deliberately terminated by us vs one that is killed by external signal.
This change was tested to ensure it didn't interfere with ctrl-c operation (it doesn't - we order termination of all jobs when we get a ctrl-c).

1. ensure that orte_rmaps_base_schedule_policy does not override cmd line settings
2. when you try to bind to more cores than we have, generate a not-enough-processors error message
3. allow npersocket -bind-to-core combination - because, yes, somebody actually wants to do it.
This commit was SVN r21996.
1. default -npersocket to force -bind-to-socket
2. if we cannot get a value for cores/socket, try using #logical cpus. otherwise, default to 1 core
3. add missing error message for not-enough-processors
4. since we no longer loop through orte_register_params twice, put the auto-detect of
topology info in the rte_init for hnp and std_orted
5. fix bind-to-core, bysocket combination
This commit was SVN r21992.
The new options work by adding an ":if-avail" qualifier to the "bind-to-socket" and "bind-to-core" MCA params. If the system does not support this capability, the job will launch anyway. Without the qualifier, the job will abort with an error message indicating that the required functionality is not supported on this system.

1. finalize the logic for properly respecting externally assigned bindings. Thanks to Chris Samuel for his help with this. Still needs some acid testing, but appears to now work.
2. remove the double-logic of requiring opal_paffinity_alone AND bind-to-foo. If the user specifies bind-to-foo, trust her and just do it.
This commit was SVN r21885.
I have no machine which allows me to do external binding, so I will have to ask others to test the new logic. However, I did verify that these changes don't break the existing logic when no external bindings were present.
This commit was SVN r21842.
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.
Documentation to follow...

Update the loop_spawn test to remove a sleep so that it runs at max speed, letting the new code catch when we overrun ourselves and wait for room to be cleared for the next comm_spawn.
This commit was SVN r21390.
messages when delivering a signal (like STOP or CONT)
to a non-existant process. This fixes trac:1929.
Also, only print one error message in the other cases.
This commit was SVN r21263.
The following Trac tickets were found above:
Ticket 1929 --> https://svn.open-mpi.org/trac/ompi/ticket/1929
Add a new tm ess module that exploits this capability.
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 commit was SVN r21248.
1. replacing mpi_paffinity_alone with opal_paffinity_alone - for back-compatibility, I have aliased mpi_paffinity_alone to the new param name. This caus
es a mild abstraction break in the opal/mca/paffinity framework - per the devel discussion...live with it. :-) I also moved the ompi_xxx global variable
that tracked maffinity setup so it could be properly closed in MPI_Finalize to the opal/mca/maffinity framework to avoid an abstraction break.
2. Added code to the odls/default module to perform paffinity binding and maffinity init between process fork and exec. This has been tested on IU's odi
n cluster and works for both MPI and non-MPI apps.
3. Revise MPI_Init to detect if affinity has already been set, and to attempt to set it if not already done. I have *not* tested this as I haven't yet f
igured out a way to do so - I couldn't get slurm to perform cpu bindings, even though it supposedly does do so.
This has only been lightly tested and would definitely benefit from a wider range of evaluation...

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.
In case we use memcmp, strlen, strup and friends include <string.h>
Also several constants.h are not included directly
- Let's have mca_topo_base_cart_create return ompi-errors in
ompi/mca/topo/base/topo_base_cart_create.c
