WHAT: add the ompio io module and new parallel io frameworks to trunk TIMEOUT: 08/22/2011
DETAILS: we would like to bring the ompio module and the new parallel io frameworks to the trunk to expose it to a wider set of platforms and more widespread testing. The current functionality - while not yet providing the full functionality of MPI I/O - is already useful, since all blocking individual and collective I/O operations (arbitrary file views, implicit and explicit offset) are supported. The missing functionality ( non-blocking individual I/O and shared file pointers) are currently being worked on and exist partially as stand-alone libraries. The current goal is to enable compilation of the new modules and frameworks per default, but not use them unless explicitly requested by the user, i.e. ROMIO will remain the default selection. Very little existing code is being touched, since most of the new code are new frameworks and modules. If somebody would like to have a look at the code and the changes, here isa public repository with the code. https://bitbucket.org/mschaara/ompio The list of modified files are: ? ompi/mca/fbtl ? ompi/mca/sharedfp ? ompi/mca/fcoll ? ompi/mca/fs ? ompi/mca/fcache ? ompi/mca/io/ompio M ompi/mca/io/romio/src/io_romio_component.c M ompi/mca/io/base/io_base_file_select.c M ompi/mca/io/base/io_base_delete.c ? ompi/config/ompi_check_pvfs2.m4 ? ompi/config/ompi_check_lustre.m4 Feedback is highly welcome.
