On our system the serial version of amber8 compiles without error but
the parallel version does not compile. I've looked but cannot find the
missing libraries. I get many messages of the form:
egb.o(.text+0x1eeb): In function `genborn_mp_egb_':
: undefined reference to `mpi_allreduce_'
sander.o(.text+0x28): In function `MAIN__':

debug.o(.text+0x74a): In function `debug_frc_':

The following variables were set:
AMBERHOME
MKL_HOME
LAM_HOME
Fortran Compiler ==> The Intel Fortran Compiler 9.0 for Linux
MKL ==> Math Kernel Library 8.0.1
I configured with both .configure -lam ifort and .configure -lam -static
ifort
Any suggestions would be appreciated.
Best regards,
