MCA/base: Add new MCA variable system 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. This commit was SVN r28236.

Upgrade the system limit code to support a broader range of parameters. For now, we support stack size, #open files, #children, and file size we can c reate. Continue to support the old "1" or "0" options for backward compatibility. This commit was SVN r28282.

re-introduce distill_checkpoint_ready In the OPAL_ENABLE_FT_CR code path there used to be a variable 'mca_base_component_distill_checkpoint_ready' which got removed. The FT code was not compiling and while trying to get it to compile again the old variable was #ifdef'd out. This re-introduces the variable with a new name 'opal_base_distill_checkpoint_ready' and enables the code previously #ifdef'd out. This removes the last hack introduced to get the FT code to compile again. This commit was SVN r30928.

[Contribution from Artem - moved it to svn from git for him] Replace our old, clunky timing setup with a much nicer one that is only available if configured with --enable-timing. Add a tool for profiling clock differences between the nodes so you can get more precise timing measurements. I'll ask Artem to update the Github wiki with full instructions on how to use this setup. This commit was SVN r32738.

#if OPAL_ENABLE_TIMING
Fix timing framework: 1. Fixes according to (http://www.open-mpi.org/community/lists/devel/2014/09/15869.php) 2. Force mpisync:rank0 to gather results. Now sync info is written by rank0 to the output file. 3. Improve mpirun_prof: 1) adopt to the environment (SLURM/TORQUE); 2) recognize some noteset-related mpirun options. This commit was SVN r32772.

George did the work and deserves all the credit for it. Ralph did the merge, and deserves whatever blame results from errors in it :-) WHAT: Open our low-level communication infrastructure by moving all necessary components (btl/rcache/allocator/mpool) down in OPAL All the components required for inter-process communications are currently deeply integrated in the OMPI layer. Several groups/institutions have express interest in having a more generic communication infrastructure, without all the OMPI layer dependencies. This communication layer should be made available at a different software level, available to all layers in the Open MPI software stack. As an example, our ORTE layer could replace the current OOB and instead use the BTL directly, gaining access to more reactive network interfaces than TCP. Similarly, external software libraries could take advantage of our highly optimized AM (active message) communication layer for their own purpose. UTK with support from Sandia, developped a version of Open MPI where the entire communication infrastucture has been moved down to OPAL (btl/rcache/allocator/mpool). Most of the moved components have been updated to match the new schema, with few exceptions (mainly BTLs where I have no way of compiling/testing them). Thus, the completion of this RFC is tied to being able to completing this move for all BTLs. For this we need help from the rest of the Open MPI community, especially those supporting some of the BTLs. A non-exhaustive list of BTLs that qualify here is: mx, portals4, scif, udapl, ugni, usnic. This commit was SVN r32317.

Fix the calls to ibv_fork_init and remove btl_openib_want_fork_support. In order to have an effect, ibv_fork_init should be called in the beginning of the verbs initialization flow - before the calls to the ibv_create_qp and ibv_create_cq verbs. These functions are called from the oob/ud code and by the time the other verbs components (btl openib, pml yalla, ...) call ibv_fork_init, it's too late. This commit forces the call to ibv_fork_init (if it's requested) right at the beginning of all the components that are using verbs. (ibv_fork_init() can be safely called multiple times) This commit also removes the btl_openib_want_fork_support mca parameter and adds a new mca parameter instead - opal_verbs_want_fork_support. Through this new parameter, fork support may be requested for ALL components. The default value for this parameter is set to 1. Before this commit the btl_openib_want_fork_support parameter didn't provide fork support for the openib btl if its value was set to 1. (because when openib called ibv_fork_init, it was already after the calls to ibv_create_* in oob/ud and thereofre it failed).
