Subject: AMBER: Compilation problem at dual processor linux !

Apologies if this is a FAQ.

I am trying to compile AMBER7 in a dual processor Linux machine

The operating system is GNU/LINUX

The hardware platform is i386

I have done the following steps:

 Installed MPICH-1.2.6

 Compiled AMBER7 after defining $AMBERHOME and $MPICH_HOME

Compilation was done without problem. But when I start to run the
sander test job (I defined
DO_PARALLEL="/home1/fac/pradipta/MPI/mpich-1.2.6/bin/mpirun -np 2")

I got the following error
--------------------------------------------------------------------------
cd dmp; ./Run.dmp
This test not set up for parallel
 cannot run in parallel with #residues < #pes
cd adenine; ./Run.adenine
This test not set up for parallel
 cannot run in parallel with #residues < #pes
==============================================================
cd cytosine; ./Run.cytosine
quantum: Connection refused
p0_14945: p4_error: Child process exited while making connection to
remote process on quantum: 0

/home1/fac/pradipta/AMBER/amber7/test/cytosine
  Program error
make: *** [test.sander] Error 1

----------------------------------------------------------------------
quantum is the name of the network node hostname - somehow two processors
can not communicate.

Can somebody please help me with this?

thanks,

  Pradipta
