MPI_File_write_shared/ordered)?
There was a fix which removed a warning/error about not being to delete
the file when using shared file pointer around v.1.2.6 ( I don't
remember precisely when it hit the trunk), and I was wandering whethe

Well, we spent some time testing the various options, and Leonardo's
suggestion seems to work!
We disabled TCP Segment Offloading on the e1000 NICs using "ethtool -K
eth tso off" and this type of crash no longer happens.
After a little digging, I am able to run your code (it looks like it
expects both an input file and an output file on the command line, or
it segv's). But I don't get those errors, either with OMPI v1.2.8 or
the upcoming v1.3 series; I ran with as many as 16 processes across 4
nodes.

can you update me with the mapping or the way to get it from the OS on the
Cell.
thanks

Sorry for the lack of reply; several of us were at the MPI Forum
meeting last week, and although I can't speak for everyone else, I
know that I always fall [way] behind on e-mail when I travel. :-\
The windows port is very much a work-in-progress. I'm not surprised
that it doesn't work.
I can't seem to run your code, either. Can you provide a more precise
description of what exactly is happening? It's quite possible /
probable that Rob's old post is the answer, but I can't tell from your
original post -- there just aren't enough details.
Thanks.

I think the KINDs are compiler dependent. For Sun Studio Fortran,
REAL*16 and REAL(16) are the same thing. For Intel, maybe it's
different. I don't know. Try running this program:
double precision xDP
real(16) x16
real*16 xSTAR16
write(6,*) kind(xDP), kind(x16), kind(xSTAR16), kind(1.0_16)
I dabble in Fortran but am not an expert -- is REAL(kind=16) the same
as REAL*16? MPI_REAL16 should be a 16 byte REAL; I'm not 100% sure
that REAL(kind=16) is the same thing...?

I take it this is using OMPI 1.2.x? If so, there really isn't a way to
do this in that series.
If they are using 1.3 (in some pre-release form), then there are two
