This commit adds support for project_framework_component_* parameter matching. This is the first step in allowing the same framework name in multiple projects. This change also bumps the MCA component version to 2.1.0. All master frameworks have been updated to use the new component versioning macro. An mca.h has been added to each project to add a project specific versioning macro of the form PROJECT_MCA_VERSION_2_1_0. Signed-off-by: Nathan Hjelm <hjelmn@me.com>

/*
|
|
* The file byte transfer layer (fbtl) framework provides the abstraction
|
|
* for individual blocking and non-blocking read and write operations.
|
|
* The functionality provided by the interfaces in this module
|
|
* can be used to implement the corresponding operations in MPI I/O.
|
|
* Note however, that the interfaces are not a one-to-one mapping
|
|
* of the MPI individual read and write operations, since the fbtl framework
|
|
* avoids using derived MPI datatypes. The step mapping/unrolling the MPI
|
|
* derived data types into a vector of (offset into file, memory address, length)
|
|
* is done in the OMPIO module of the IO framework.
|
|
*
|
|
* These are the component function prototypes. These function pointers
|
|
* go into the component structure. These functions (query() and finalize()
|
|
* are called during fbtl_base_select(). Each component is query() ied
|
|
* and subsequently, all the unselected components are finalize() 'ed
|
|
* so that any *stuff* they did during query() can be undone. By
|
|
* similar logic, finalize() is also called on the component which
|
|
* was selected when the communicator is being destroyed.
|
|
*
|
|
* So, to sum it up, every component carries 4 functions:
|
|
* 1. open() - called during MPI_INIT
|
|
* 2. close() - called during MPI_FINALIZE
|
|
* 3. query() - called to select a particular component
|
|
* 4. finalize() - called when actions taken during query have
|
|
* to be undone
