offset is of the type MPI_OFFSET_KIND which seems insuficient to hold the
correct size for the offset.
So... am I condemned to write my own MPI data type so I can write the
files? ideas... ?

shouldn't this behaviour be found with MPI-IO? And, more to the point, if
not, shouldn't it be documented somewhere?
Does anyone knows if this carries over to other MPI implementations (or
the answer is "download, try it and tell us?")

Thanks. So in an asynchronous write, the old buffer would only be
available after the I/O ended. So maybe I really need to think to set some
process aside just for I/O...

Hi all
I have a doubt. I'm starting using MPI-IO and was wondering if I can use
the MPI_BUFFER_ATTACH to provide the necessary IO buffer (or will it use
the array I'm passing the MPI_Write...??)

n flush it.
Yes, I know. But this should function if the Barrier would be working has
supposed. I've seen it working previously and I'm seing it working in
other MPI implementations (mvapich)
So, what's the catch?

What do you need for this to happen? The intel packages? I can give you

Do the intel compilers come with any error checking tools to give

yes, they come with their own debugger. I'll try to use it and send more
