Lustre discuss - Jun 2009 - Réf. : Re: [ROMIO Req #940] a new Lustre ADIO driver]

Hi Rob,


I''ve compiled the romio coming with mpich2 version 1.1rc1 and added
some
modifications,

 I ran the script ''runtests'' and  I still have problems with 4
tests:
i_noncontig : abort
 noncontig: abort
 noncontigcoll: errors
 noncontigcoll2: Fatal errors

All other tests are OK.

I''ll take you informed of my progress.

Pascal

Hi Pascal.  Did these tests fix things for you?  You''re right: one of
the bigger changes from 1.0 to 1.1 was an effort to make ROMIO more
64-bit clean.

If you go to the ''romio/test'' directory, there''s a
script ''runtests''
that will run through a good number of MPI-IO tests:

''runtests -fname=lustre:/path/to/lustre''

If you run that, let me know how it goes.

i_noncontig and noncontig require fcntl() locks, which Lustre supports
only if you mount with a special mount option (I don''t remember what
that is).   Was that the cause for the ''abort''  (it should be
pretty
clear from the error messages).

If coll_test passed, that''s very good progress.  

Can you tell me more about the noncontig_coll and noncontig_coll2 test
failures?  

thanks
