[mvapich-discuss] hydra with disabled AcceptEnv /SendEnv in ssh config

[Jonathan Perkins]

Instead of adding rpath to the compiler wrappers, try adding the rpath
to the mvapich2 library.  You can do this at configure time by the
following...

./configure CC=icc CXX=icpc FC=ifort F77=ifort
LDFLAGS='-Wl,-rpath,/path/to/intel/library/directory' ...

This will embed the rpath into the mvapich2 library (and launcher
executables) which will most likely resolve your problem.  This is of
course assuming that your real problem is that the hydra proxy isn't
finding the intel libraries when being launched.

Let us know if this helps.
