The preload-binary problem had to do with how we were resolving
relative path names before moving files. While fixing these bugs I
also cleaned up some error reporting mechanisms.
I believe that I have fixed both the --preload-binary and --preload-
files options in the trunk (r20331). If you want to test the patch
before the release I attached it to the ticket. The patch should
apply cleanly to the v1.3 release and SVN branch.
https://svn.open-mpi.org/trac/ompi/ticket/1770
Let me know if you run into any more problems with this
functionality. There are a few places that still need to be cleaned
up, but I think this should work much better for you now. I'll file a
request to have this moved into the v1.3.1 release.
Thanks,
Josh

Josh,
It sounds like . is not in your path. That would prevent mpirun
from seeing the binary in the current directory.

As a followup.
I can confirm that --preload-files is not working as it should.
I was able to use --preload-binary with a full path to the binary
without a problem though. The following commands worked fine
(where /tmp is not mounted on all machines):
shell$ mpirun -np 2 --preload-binary /tmp/hello
shell$ mpirun -np 2 -s /tmp/hello
However if I referred directly to the binary in the current
directory I saw the same failure:
shell$ cd /tmp
shell$ mpirun -np 2 -s hello

mpirun was unable to launch the specified application as it could

I'll keep digging into this bug, and let you know when I have a
fix. I filed a ticket (below) that you can use to track the
progress on this bug.

Thanks again for the bug report, I'll try to resolve this soon.

The warning is to be expected if the file already exists on the
remote side. Open MPI has a policy not to replace the file if it
already exists.
The segv is concerning. :/
I will take a look and see if I can diagnose what is going on
here. Probably in the next day or two.
Thanks for the bug report,

Hello,
As you can notice , I am trying the work done on this new
release. preload-files and preload-binary options are very
interesting to me because I work on a cluster without any shared
space between nodes.
I tried those basically , but no success . You will find below
the error messages.
If I did things wrong, would it be possible to get simple
examples showing how these options work.
Thanks
