The primary issue with udcm is that the immediate data in message
acks were often bogus. This caused the sender to keep trying even
though a message was received and acked. The fix is to use the
source LID and QP to determine which message is being acked. In
most cases this should work well since only one message will be
in flight to any peer.
This commit was SVN r28444.
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.

ompi_show_help, because opal_show_help is replaced with an
aggregating version when using ORTE, so there's no reason to
directly call orte_show_help.
This commit was SVN r28051.
some new common OpenFabrics functionality to ompi/mca/common/verbs.
Also move everything that was in ompi/mca/common/ofautils under
ompi/mca/common/verbs.
* Move ofautils -> verbs
* Add new functionality in ompi/mca/common/verbs (see doxygen
* comments in ompi/mca/common/verbs/common_verbs.h for details):
* ompi_common_verbs_find_ibv_ports()
* ompi_common_verbs_port_bw()
* ompi_common_verbs_mtu()
* '''If you're writing verbs-based code, you should be using this
common functionality'''
* Adapt openib BTL to use some trivial common functionality in
common/verbs
* Don't use "#ifdef OMPI_HAVE_RDMAOE",use
"#if defined(HAVE_IBV_LINK_LAYER_ETHERNET)"
* Update the following to include/link against common/verbs
* bcol/iboffload
* sbgp/ibnet
* btl/openib

btl_openib_connect_udcm when notifying not to listen to an fd to ensure
that the main thread does not continue until the service thread has
processed the message
Adds ability to send message to openib async thread to tell it to
ignore the ERR state on a specific QP. Adds this call to udcm_module_finalize
so when we set the error state on the QP it doesn't cause the
openib async thread to abort the mpi program prematurely
Fixes trac:3161
This commit was SVN r27064.
The following Trac tickets were found above:
Ticket 3161 --> https://svn.open-mpi.org/trac/ompi/ticket/3161
Roll in the ORTE state machine. Remove last traces of opal_sos. Remove UTK epoch code.
Please see the various emails about the state machine change for details. I'll send something out later with more info on the new arch.
This commit was SVN r26242.
Global rdmacm_resolve_timeout defaults to 1000 (1000 ms), which is way
too small for even a 16 node x 12 core iwarp cluster in the presence
of drops. Bump up the default to 30000ms.
This commit fixes trac:2860 and should be added to cmr:v1.4:reviewer=jsquyres
and cmr:v1.5:reviewer=jsquyres
This commit was SVN r25144.

Ticket 2860 --> https://svn.open-mpi.org/trac/ompi/ticket/2860
Don't juse include pre-processor macros between two strins ("s1" #if 0 ... "s2")...
Rather print out the epoch as 0 always...
This commit was SVN r25110.
To enable the epochs and the resilient orte code, use the configure flag:
--enable-resilient-orte
This will define both:
ORTE_ENABLE_EPOCH
ORTE_RESIL_ORTE
This commit was SVN r25093.
- Added dynamic SL support to xoob
- Fixed seg fault in finalization
- All the code has been moved to separate files: connect/btl_openib_connect_sl.{c,h}
- The new files compilation is conditionalized
This commit was SVN r24991.
- Added enable/disable configuration parameter for dynamic SL
- All the dynamic SL code is conditionalized
- Removed libibmad dependency
- Using only one include - ib_types.h (part of opensm-devel package)
- Removed all the macro and data types definitions, using the
existing definitions from ib_types.h instead
- general cleaning here and there
The async mode is not implemented yet - stay tuned...
This commit was SVN r24830.
* rename ib_path_rec_service_level -> ib_path_record_service_level
* use mad.h and ib_types.h
* free all resources
* move ibv_post_recv to be just before ibv_post_send
* cleanup and beatify code
This commit was SVN r24507.
