  Satish,

    This happens on that one machine where it produces MUCH less precision then for any other block size or machine configuration. I investigated a little when it first happened and my guess is there some issue with the compiler producing "bad" code on this one system.

    I hate to have an alt file for a buggy compiler but don't have any other suggestion go ahead and add the alt file.

  Barry
