It looks like you haven't included the correct  mpi libraries, make sure in
the Make.<arch> file under the MPI libraries section you include the location
of the libmpi.a (or similar library) also the include directories should be

Hope this helps,

I'm trying to compile the High Performance Lapack benchmarking program from 
the IEEE Top Clusters Task Force page.  I'm using RedHat Linux 7.1 on 
Pentium II (with a PIII server, which can still stay at PII compile).  I'm 
trying to "make arch=Linux_PII_FBLAS", and I have downloaded the ATLAS 
binary for LINUX_PII architecture.  I'm also using lam 6.5.1.  However, 
every time I try to compile the HPL code I get many pages of errors such as:

HPL_pdinfo.o: In function `HPL_pdinfo':
HPL_pdinfo.o(.text+0x14): undefined reference to `lam_mpi_comm_world'
HPL_pdinfo.o(.text+0x23): undefined reference to `MPI_Comm_rank'
HPL_pdinfo.o(.text+0x31): undefined reference to `lam_mpi_comm_world'
HPL_pdinfo.o(.text+0x36): undefined reference to `MPI_Comm_size'

I'm not certain what is going on here, as everything in the make files 
appear correct, I've got ATLAS and BLAS and LAM installed.  Any ideas?
