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,
Josh

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
Geoffroy
