I downloaded a few of them; most do not seem to have generic MPI
specifications -- you need to edit Makefiles to get them to compile.
In general, I did the following:
-----
CC = mpicc
FC = mpif77
LD = mpif77
M4 = m4
CPP = cpp
CPPOPT = -DMPI
INCDIR = -I/lam/prefix/directory/include

Ensure that you compiled LAM with Fortran support; you may want to use the
"--with-fc=f90" (or whatever the name of your F90 compiler is) option when
configuring LAM. If you didn't, mpif77 will represent a Fortran 77
compiler. You can override this behavior at mpif77 run time by setting
the LAMHF77 environment variable to "f90" (or whatever the name of your
fortran compiler is).
Note that at least some of the benchmarks assume that mpif.h is either in
the present directory or the specified in the INCDIR macro, so you may
need to set it as appropriate (replace "/lam/prefix/directory" with the
actual prefix directory where you installed LAM).
In general, that's all that you need to get it to compile successfully
with LAM/MPI.
Note that there's also lots of other compiler behavior and optimization
flags that you may want to tweak depending on what compiler, hardware,
operating system, etc. you are using. These will likely have a large
effect on the actual performance of the code.
