ptr is uninitialized when sent by task 0, isn't it ?

Howard,
Welp. That worked! I'm assuming oshmem = OpenSHMEM, right? If so, yeah, for
now, not important on my wee workstation. (If it isn't, is it something I
should work on getting to work?)

HI Matt,
If you don't need oshmem, you could try again with --disable-oshmem added
to the config line

All,
I'm trying to duplicate an issue I had with ESMF long ago (not sure if I
reported it here or at ESMF, but...). It had been a while, so I started
from scratch. I first built Open MPI 1.10.2 with Intel Fortran 16.0.0.109
and my system GCC (4.8.5 from RHEL7) with mostly defaults:
# ./configure
Thanks for looking in to this. I am looking for other CUDA aware mpi code that
I can test on my 32 bit arm system, the Jetson TK1

It looks like the errors are produced by the hwloc configure ; this one
somehow can't find CUDA (I have to check if that's a problem btw).
Anyway, later in the configure, the VT configure finds cuda correctly,
so it seems specific to the hwloc configure.

Hi Sylvain,
The configure does not stop, 'make all install' completes. After remaking and
recompiling then ignoring the configure errors, and confirming both a
functional cuda install and functional openmpi install. I went to the
/usr/local/cuda/samples directory and ran 'make' and succesful
Hi Spencer,
Could you be more specific about what fails ? Did the configure stop at
some point ? Or is it a compile error during the build ?
I'm not sure the errors you are seeing in config.log are actually the
real problem (I'm seeing the same error traces on a perfectly working
machine). N

If you're starting new code, try using the F08 MPI bindings. Type safety ===
good.

You will find the MPI Fortran 2008 bindings to be significantly better
w.r.t. MPI types. See e.g. MPI 3.1 section 17.2.5 where it describes
TYPE(MPI_Status), which means that the status object is a first-class type
in the Fortran 2008 interface, rather than being an error prone INTEGER
array.

Thx a lot. I will be more careful with declaration of the MPI variables.

Thanks for the suggestion Ryan, I will remove the symlinks and start try again.
I checked config.log, and it appears that the configure finds cuda support,
(result: yes), but once configure checks for cuda.h usability, conftest.c
reports that a fatal error occurred, 'cuda.h no such file or dire

Hi Gilles,
I try 1.10.2. My program has been running successfully without
I would check config.log carefully to see what specifically failed or wasn't
found where. I would never mess around with the contents of /usr/include. That
is sloppy stuff and likely to get you into trouble someday.
