The patch I send few minutes ago will only remove the problem for Open
MPI. However, their generic test for contiguous data types is still
broken. Only checking for COMBINER_NAMED is clearly not enough. A
second test checking that the size and the extent of the data types
are equal will mak
Here is sketch of a ROMIO patch for Open MPI. I just wrote it, I
didn't had time to test it. If you can test it please let me know if
this solve the problem.
Thanks,
george.

Hi George,
Good, if You come to the same conclusion with regard to romio using
MPI_Type_size internally in RomIO...
So taking iscontig.c ,-]
/* This function needs more work. It should check for contiguity
in other cases as well.*/
and mail to the romio list or have a specialized vers
MPI_Type_size is supposed to return only the size of useful data,
which apparently it does (MPI_SHORT_INT is 6 bytes). What I think it
happens is that the MPI_SHORT_INT type is a predefined one, but it's a
really strange predefined type. It's one of the few that are not
contiguous. The prob
