* Remove the connect() timeout code, as it had some nasty race conditions
when connections were established as the trigger was firing. A better
solution has been found for the cluster where this was needed, so just
removing it was easiest.
* When a fatal error (too many connection failures) occurs, set an error
on messages in the queue even if there isn't an active message. The
first message to any peer will be queued without being active (and
so will all subsequent messages until the connection is established),
and the orteds will hang until that first message completes. So if
an orted can never contact it's peer, it will never exit and just sit
waiting for that message to complete.
* Cover an interesting RST condition in the connect code. A connection
can complete the three-way handshake, the connector can even send
some data, but the server side will drop the connection because it
can't move it from the half-connected to fully-connected state because
of space shortage in the listen backlog queue. This causes a RST to
be received first time that recv() is called, which will be when waiting
for the remote side of the OOB ack. In this case, transition the
connection back into a CLOSED state and try to connect again.
* Add levels of debugging, rather than all or nothing, each building on
the previous level. 0 (default) is hard errors. 1 is connection
error debugging info. 2 is all connection info. 3 is more state
info. 4 includes all message info.
* Add some hopefully useful comments

1. Remove a unneeded field, bytes_avail, from orte_buffer_t. It is a calcualed value, and updating it everywhere is worse then just calculating it in the one place it is acutally used.
2. Change it so the default size of a orte_buffer is 128 bytes instead of 1024 bytes. We then double the size of the buffer up to 1024 bytes, then we additively increase the size by 1024 bytes at a time as was done before.

* Do not empty the list of in-flight frags during _close(); the OOB
callback will still occur (_send_cb()) and try to remove the frag
from the list, which will then result in an assert failure (debug
builds).
* Add one more fix for a possible problem -- add an extra RETAIN /
RELEASE pair on the endpoint to ensure that it is not actually
freed before all in-flight frags have drained.

- mca_base_param_file_prefix
(Default: NULL)
This is the fullname of the "-am" mpirun option. Used to specify a ':'
separated list of AMCA parameter set files.
- mca_base_param_file_path
(Default: $SYSCONFDIR/amca-param-sets/:$CWD)
The path to search for AMCA files with relative paths. A warning will be
printed if the AMCA file cannot be found.
* Added a new function "mca_base_param_recache_files" the re-reads the file
configurations. This is used internally to help bootstrap the MCA system.
* Added a new orterun/mpirun command line option '-am' that aliases for the
mca_base_param_file_prefix MCA parameter
* Exposed the opal_path_access function as it is generally useful in other
places in the code.
* New function "opal_cmd_line_make_opt_mca" which will allow you to append a
new command line option with MCA parameter identifiers to set at the same
time. Previously this could only be done at command line declaration time.
* Added a new directory under the $pkgdatadir named "amca-param-sets" where all
the 'shipped with' Open MPI AMCA parameter sets are placed. This is the first
place to search for AMCA sets with relative paths.
* An example.conf AMCA parameter set file is located in
contrib/amca-param-sets/.
* Jeff Squyres contributed an OpenIB AMCA set for benchmarking.
Note: You will need to autogen with this commit as it adds a configure param.

its bigger than the timeout for the connect() call, just don't register
the handler by default and fall back to connect() timing out. Should give
much happier performance on big clusters.

Adjust the RMAPS mapped_node object to propagate the required launch_id info now included in the ras_node object. This provides support for those few systems that don't use nodename to launch, but instead want some id (typically an index into the array of allocated nodes). This value gets set for each node in the RAS - the RMAPS just propagates it for easy launch.

This change utilizes the new num_processors function. I also left the mods made to ompi_mpi_init and the bug fix for the default value of mpi_yield_when_idle. Note that the mods to mpi_init will not really take effect as the mca param will now *always* be set (either by user or odls). We will need those mods later, so no point in removing them now.

processes. The killing of processes is ifdef'ed out for Windows
since I do not know how to do it there. Note that this change
will requite an autogen.

1. if the user has specified sched_yield, we simply do what we are told
2. if they didn't specify anything, try to get the number of processors on this node. Note that we already now get the number of local procs in our job that are sharing this node - that now comes in through the proc callback and is stored in the ompi_proc_t structures.
3. if we can get the number of processors, compare that to the number of local procs from my job that are sharing my node. If the number of local procs exceeds the number of processors, then set sched_yield to true. If not, then be a hog and set sched_yield to false
4. if we can't get the number of processors, default to conservative behavior and set sched_yield to true.
Note that I have not yet dealt with the need to dynamically adjust this setting as more processes are added via comm_spawn. So far, we are *only* looking within our own job. Given that we have now moved this logic to mpi_init (and away from the orteds), it isn't yet clear to me how a process will be informed about the number of procs in *other* jobs that are also sharing this node.
Something to continue to ponder.

Tested this functionality quite a bit more and made some fixes:
* Print far fewer help messages
* Fix one additional deadlock upon error
* Change some ORTE_LOG messages to silent (because they're not
errors)
* Some code got re-indented, sorry...

yesterday and set it to "true" in orte_init(). But ompi_mpi_init()
doesn't call orte_init() -- it calls orte_init_stage1() and
orte_init_stage2(). So orte_initialized was never set to true, and
Badness happend from there (w.r.t. ompi_mpi_abort()).
This patch moves the setting of orte_initialized to orte_init_stage2()
so that everyone will always get it set properly.
It also moves setting orte_universe_info.state to RUNNING into
stage2() as well -- Ralph confirmed that that should have been there
for the same reasons that orte_initialized needs to be there.

completed successfully, Bad Things(tm) could happen.
* Now we explicitly check orte_initialized (a new global in ORTE
indicating whether we are between orte_init() and orte_finalize()
or not), and if so, react accordingly.
* If ORTE is initialized, use orte_system_info.nodename; otherwise,
use gethostname().
* Add loop protection to ensure that ompi_mpi_abort() is not invoked
multiple times recursively.

and George on these refinements):
* Rename the static OBJ initializer macro to be
OPAL_OBJ_STATIC_INIT(class)
* Ensure that all static OBJ initializations get a refcount of 1
(doesn't ''really'' matter, since they're static, it should never
get to the point where the OBJ is DESTRUCTed, but more correct
nonetheless)
* Add a "magic number" to the OBJ when compiling with debug support.
The magic number does some rudimentary support to ensure that
you're operating on a valid OBJ (and fails an assertion if you're
not). Check to ensure that the memory contains the magic number
when performing actions of OBJ's. Also remove the magic number
when DESTRUCTing OBJs, so that if, for example, an OBJ is
DESTRUCTed more than once, we'll fail the magic number assert.

This commit was SVN r13320.
1. add a "cancel_operation" API to the pls components that allows orterun to demand that an orted operation (e.g., terminate_job) be immediately cancelled and abandoned.
2. changes the pls orted commands from blocking to non-blocking. This allows us to interrupt those operations should an orted be non-responsive. The change also adds an orte_abort_timeout that limits how long orterun will automatically wait for the orteds to respond - if the terminate command, for example, doesn't see orted response within that time, then we printout an appropriate error message and just give up.
3. modifies orterun to allow multiple ctrl-c's to simply abort the program even if the orteds have not responded
4. does some cleanup on the orte-level mca params so that their implementation looks a lot more like that of ompi - makes it easier to maintain. This change also includes the definition of an orte_abort_timeout struct and associated MCA param (can't have too many!) so you can set the time after which orterun gives up on waiting for orteds to respond
This needs more testing before migrating to 1.2.
This commit was SVN r13304.
This fix includes two parts: (a) we now initialize the keyval pointer locations to NULL after the malloc, and (b) we now OBJ_NEW the keyvals prior to storing info in them.
BTW, in case anyone reads this and wonders why we don't just OBJ_NEW the keyvals in create_value, the reason is simply that some places in the code use static keyvals and simply assign those addresses into the value object's array. So not everyone wants to OBJ_NEW keyvals - by not forcing it here in create_value, we give the user the flexibility to do whatever they want.
