the contiguous datatype correctly and fast. However in the "developer mode" (OMPI_ENABLE_DEBUG set to 1) there are additional test that are made. If you plan to look for performances please compile OpenMPI in normal mode. Changes: - correctly generate the stack when we have an initial position - same thing when we start from ZERO. - in contiguous mode handle the partial copy of a data (using the stack) - in the case when not all the data is packed/unpacked leave the stack in a correct state - take care of data with size ZERO (who really want to create such things !!!) - general pack/unpack functions handle the new stack representation - make sure that we never goes outside the user provided buffer This commit was SVN r3581.
This is the world's greatest MPI. ...more to write here should be a short file, referring to the real docs.
