Re: [BProc] Valgrind and BProc (again)

[Greg W. <gw...@la...>]

I don't know of anyone using it, but it seems to me that the simplest  
way would be to NFS mount a filesystem on the nodes. That way  
valgrind will be able to find the executable. Otherwise you could  
copy the foo executable to the node using bpcp.
