Charm++ parallel programming system

[Jeff Hammond <jeff.science AT gmail.com>]

Phil: Please do not apologize for the catastrophic failure of the MPI
Forum in not foreseeing this issue.  It should have been solved 10
years ago with MPI::FILE_SEEK_SET (or something like that).  One
should also blame C preprocessing for not respecting C++ namespaces,
which is the source of all sorts of absolutely disgusting problems.

In any case, doesn't "-DMPICH_IGNORE_CXX_SEEK" solve this trivially?
Of course it's nice if Charm++ handles it, but I would have thought
that users could work around immediately.  I know this is discussed on
the ticket, but your response here seems to hedge as if that's not a
sufficient solution...

Best,

Jeff
