4a5d3e705b remove an unecessary comm_dup in case the internal file_open function is called from a sharedfp component. 2015-01-28 16:13:50 -06:00

51cee4a083 call the actual backend functions for file_get_position_shared and file_seek_shared. The sharedfp components 
do provide the implementations, we just did not invoke them yet.

dc05b709a7 it is ok to not have a sharedfp component selected, as long as no 
sharedfp functionality is being used. Return an error however if no
sharedfp component is selected and the applications calls a
file_read/write_shared function.

  for explicit offsets

f7391eca23 Lazy open does not work for the addproc sharedfp component since it starts by 
spawning a process using MPI_Comm_spawn. For this, the first operation has to
be collective which we can not guarantuee outside of the MPI_File_open
operation.

ac694b7056 in preparation for the new shared file pointer components to be committed 
soon:
 - add a new abstraction layer to be used internally for some operations
 - add a new mca parameter to control lazy intialization of shared file
 pointer structures

9eeb3b5d50 # Extracting timing information for individual components of collective algorithm using a generic queue. 
# This is triggered based on a mca-paramater and can be used with all collective modules.
# Individual queues maintained for read and write.
# The additional communication to combine data is done at file-close so that the 
  actual timing of collective-operations will not get affected. 
# The queues are initialized in file-open

66c5a80dfd - get rid of a warning about an unused variable 
- return MPI_ERR_OTHER instead of MPI_SUCCESS for the functions that are not
  yet implemented 
- add another field to the mca_io_ompio_file_t structure to point back to the
  ompi_file_t structure.

196c3819e2 - revamp the configure logic to detect pvfs2 and lustre 
- slight change in the selection logic of the fs module, which makes
   the ompio independent of the file system type (otherwise ompio 
   would also have required a configure script).
