/*
|
|
* 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
