Charm++ parallel programming system

Hi Tom,

Thanks for the reply.  I'm learning how to run a code being developed here at UCSD.

Your suggestion did the trick.  Thanks very much!

Hi Britton,

I wonder which application you are using?

The way I got it to work was to use the "++remote-shell" option to charmrun.  E.g. on stampede, I would start the application with:

./charmrun +p $proc ++mpiexec ++remote-shell $HOME/bin/mympiexec ./ChaNGa agora.param

and in $HOME/bin/mympiexec, I would set environment variables (again this is specific for stampede):

#!/bin/csh
# echo command: $*
setenv LD_LIBRARY_PATH $HOME/local/lib:$LD_LIBRARY_PATH
shift; shift; exec ibrun $*

But perhaps the charm developers have a better idea.

Hi everyone,
I'm very new to charm++, so please forgive the basic nature of this
question.

I've compiled an application with charm++ that depends on a few other
libraries that I've installed in a local directory.  The code compiles just
fine, but when I try to run it with charmrun, the locally installed
libraries can't be found.  I set my LD_LIBRARY_PATH to include the local
installation paths in a .bash_aliases file, but that doesn't seem to work
with charmrun.  The code runs correctly when I include the "++local"
option, but not without.

Is there another way to provide library paths for executables to charmrun?

In case it helps, I'm using charm++ 6.7.1 on a linux machine running ubuntu
17.04.

Thanks for the help,

Britton
