this error message comes from ompio, the split collective are not
properly implemented at this point in time, they are basically just a
printf statement. Once I have the non-blocking collectives re-enabled,
it should be trivial add these interfaces to the list as well.
That being said, since I spent quite some time debugging the I/O tests
in mpi_test_suite, I would recommend *not* to use that for I/O
validation. I found some fundamental mistakes in the test suite, (e.g.
writing with a file view, reading back without the file view and
assuming that the byte pattern is the same) that I can not easily fix.
Thanks

Hi Folks,
I"m trying to run the mpi_test_suite test from ompi-tests. I'm noticing
that if I try to run the io tests, I get an error in the read_all_begin
test:
STATIC READ ALL BEGIN
STATIC READ ALL END
(io/tst_file_read_all_begin.c:82) ERROR: Error in position; Invalid
argument(22)(io/tst_file_read_all_begin.c:82) ERROR: Error in position;

-------------------------------------------------------
Are there known issues with the io tests? My first guess is yes
since I notice esslingen is excluding io from their MTT runs.
Thanks for any info,
Howard
