View Full Version : [all variants] compiling High Performance Computing Linpack Benchmark

I'm trying to compile HPL to get the flops performance of my computer. In short, I'm building a beowulf cluster and this program is evidently what is used to benchmark one. I figured that I would try it on my home computer first for comparisons sake. However, I'm having some trouble compiling it.

The instructions read

1) Retrieve the tar file, then

gunzip hpl.tgz; tar -xvf hpl.tar

this will create an hpl directory, that we call below the
top-level directory.

2) Create a file Make.<arch> in the top-level directory. For
this purpose, you may want to re-use one contained in the
setup directory. This file essentially contains the compilers
and librairies with their paths to be used.

3) Type "make arch=<arch>". This should create an executable
in the bin/<arch> directory called xhpl.

For example, on our Linux PII cluster, I create a file called
Make.Linux_PII in the top-level directory. Then, I type
"make arch=Linux_PII"
This creates the executable file bin/Linux_PII/xhpl.

Seems simple enough. I create a file Make.HPL in the directory and type

sudo make arch=HPL
at which point i get a bunch of scrolling text that generally repeats itself and doesn't stop till I hit ctrl+c.
Sample:

make[27]: [refresh_src] Error 127 (ignored)
makes/Make.blas src/blas/HPL/Makefile
make[27]: execvp: makes/Make.blas: Permission denied
make[27]: [refresh_src] Error 127 (ignored)
makes/Make.comm src/comm/HPL/Makefile
make[27]: execvp: makes/Make.comm: Permission denied
make[27]: [refresh_src] Error 127 (ignored)
makes/Make.grid src/grid/HPL/Makefile
make[27]: execvp: makes/Make.grid: Permission denied
make[27]: [refresh_src] Error 127 (ignored)
makes/Make.panel src/panel/HPL/Makefile
make[27]: execvp: makes/Make.panel: Permission denied
make[27]: [refresh_src] Error 127 (ignored)
makes/Make.pauxil src/pauxil/HPL/Makefile
make[27]: execvp: makes/Make.pauxil: Permission denied
make[27]: [refresh_src] Error 127 (ignored)
makes/Make.pfact src/pfact/HPL/Makefile
make[27]: execvp: makes/Make.pfact: Permission denied


What am I doing wrong?

Hi,

I have got the same problem here. Any new ideas?

Hello! I'm also trying to get HPL working...

I get:

make[2]: [leaf] Error 1 (ignored)
( cd src/pfact/Linux_P2 ; \
ln -s /home/emil/hpl/Make.Linux_P2 Make.inc )
In file included from /home/emil/hpl/include/hpl.h:80,
from ../HPL_fprintf.c:50:
/home/emil/hpl/include/hpl_pmisc.h:54:17: error: mpi.h: No such file or directory

In "hpl_pmisc.h" there is just the normal "include mpi.h".

I got an mpi.h in /usr/include/mpich2/mpi.h, but how do I get make search there?

If you're interested in benchmarking intel cpus only,

http://software.intel.com/en-us/articles/intel-math-akernel-library-linpack-download/

will help.

Still, I would be very interested if someone managed to compile it and wants give some instructions.

Best regards,

Link seems to be dead, found this though.

Found a solution

on the make file comment the MPI section and change the compiler/linker section like below. The mpicc wrapper will deal with the dependencies.


# ----------------------------------------------------------------------
# - Message Passing library (MPI) --------------------------------------
# ----------------------------------------------------------------------
# MPinc tells the C compiler where to find the Message Passing library
# header files, MPlib is defined to be the name of the library to be
# used. The variable MPdir is only used for defining MPinc and MPlib.
#
#MPdir = /usr/lib64/mpich2
#MPinc = -I$(MPdir)/include
#MPlib = $(MPdir)/lib/libmpich.a

# ----------------------------------------------------------------------
# - Compilers / linkers - Optimization flags ---------------------------
# ----------------------------------------------------------------------
#
CC = /usr/bin/mpicc
CCNOOPT = $(HPL_DEFS)
CCFLAGS = $(HPL_DEFS) -fomit-frame-pointer -O3 -funroll-loops
#
# On some platforms, it is necessary to use the Fortran linker to find
# the Fortran internals used in the BLAS library.
#
LINKER = /usr/bin/mpicc
LINKFLAGS = $(CCFLAGS)
