Re: AMBER: Problem in compiling AMBER8 parallel version

Hi Lu,

I believe you need to make the executable using an additional option for
parallel compilation like -mpich (for MPICH library) or -lam (for the
LAM library). Other parallel options are listed in the configure script
itself.

Hope this helps,
