Notes:
- This commit also eliminates the need for an available components list in use
in several frameworks. None of the code in question was making use of the
priority field of the priority component list item so these extra lists were
removed.
- Cleaned up selection code in several frameworks to sort lists using opal_list_sort.
- Cleans up the ompi/orte-info functions. Expose the functions that construct the
list of params so they can be used elsewhere.
patches for mtl/portals4 from brian
missed a few output variables in openib
This commit was SVN r28241.
Features:
- Support for an override parameter file (openmpi-mca-param-override.conf).
Variable values in this file can not be overridden by any file or environment
value.
- Support for boolean, unsigned, and unsigned long long variables.
- Support for true/false values.
- Support for enumerations on integer variables.
- Support for MPIT scope, verbosity, and binding.
- Support for command line source.
- Support for setting variable source via the environment using
OMPI_MCA_SOURCE_<var name>=source (either command or file:filename)
- Cleaner API.
- Support for variable groups (equivalent to MPIT categories).
Notes:
- Variables must be created with a backing store (char **, int *, or bool *)
that must live at least as long as the variable.
- Creating a variable with the MCA_BASE_VAR_FLAG_SETTABLE enables the use of
mca_base_var_set_value() to change the value.
- String values are duplicated when the variable is registered. It is up to
the caller to free the original value if necessary. The new value will be
freed by the mca_base_var system and must not be freed by the user.
- Variables with constant scope may not be settable.
- Variable groups (and all associated variables) are deregistered when the
component is closed or the component repository item is freed. This
prevents a segmentation fault from accessing a variable after its component
is unloaded.
- After some discussion we decided we should remove the automatic registration
of component priority variables. Few component actually made use of this
feature.
- The enumerator interface was updated to be general enough to handle
future uses of the interface.
- The code to generate ompi_info output has been moved into the MCA variable
system. See mca_base_var_dump().
opal: update core and components to mca_base_var system
orte: update core and components to mca_base_var system
ompi: update core and components to mca_base_var system
This commit also modifies the rmaps framework. The following variables were
moved from ppr and lama: rmaps_base_pernode, rmaps_base_n_pernode,
rmaps_base_n_persocket. Both lama and ppr create synonyms for these variables.

flags, and mca flags are kept seperate until the very end. The main configure
wrapper flags should now be modified by using the OPAL_WRAPPER_FLAGS_ADD
macro. MCA components should either let <framework>_<component>_{LIBS,LDFLAGS}
be copied over OR set <framework>_<component>_WRAPPER_EXTRA_{LIBS,LDFLAGS}.
The situations in which WRAPPER CPPFLAGS can be set by MCA components was
made very small to match the one use case where it makes sense.

* Properly set message to MPI_MESSAGE_NULL in the right places
* Fix double free of buffer for non-contiguous blocking sends
* Remove useless debugging output
This commit was SVN r26604.
* Need to look at slot count before flowcontrol for sending to prevent
race in restart
* Need to free pending request fragments when done with the request
* A number of branch prediction optimizations for error conditions
This commit was SVN r26430.
event on the ME. The events we're likely to see are LINK (the ME was
added to the match list), PUT (weird to see first, but means that the ME
was linked to the match list and then matched), or PUT_OVERFLOW, meaning
the message was unexpected.
This commit was SVN r26199.
the ompi_message_t structure to properly initialize convertor (the peer
is available in the request in OB1, and wasn't needed when I did the
original implementation).
* Implement matched probe for the Portals4 MTL and add NULL function pointers
for the other MTLs.
* Add add_comm and del_comm functions to portals4 MTL so that direct call
almost works again.
* Add NEWS item that we've implemented matched probe
This commit was SVN r26180.
* split eq into send and receive eqs so that we can control the number
of outstanding events in send eq and ensure we never lose an ack
* Shouldn't ever truncate on short unexpected receive bocks, so don't set
the truncate bit
* Track active vs. waiting for free short unexpected receive blocks so
to ensure an active short unexpected receive block is posted coming out
of flow control. Also allow creation of "temporary" blocks which should
be released once FREE event is received.
* Slight reorganization of some code in preparation for more flow control
work.
This commit was SVN r26174.
* Only print returnable errors when verbose=1. Still print errors when
we're going to abort, since those obviously aren't returnable
This commit was SVN r25213.
* hdr_data now includes opcount and length for all messages, which is the match
bits for long and rndv messages
* Re-add probe implementation
This commit was SVN r25207.
they only add the context id to the tag selection of the underlying
messaging meachinsm.
We would like to enable an MTL to maintain its own context data
per-communicator. This way an MTL will be able to queue incoming eager
messages and rendezvous requests per-communicator basis.
The MTL will be allowed to override comm->c_pml_comm member,
since it's unused in pml_cm anyway.
