Initial steps

Create directory structure in the shared applications mount point:

 # cd /share/apps
 # mkdir benchmarks
 # mkdir benchmarks/hpcc_bench
 # cd benchmarks/hpcc_bench

Get the source:

 # wget http://icl.cs.utk.edu/projectsfiles/hpcc/download/hpcc-1.0.0.tar.gz
 # tar -zxvf hpcc-1.0.0.tar.gz

Build the application:

Please refer to README.txt located in the hpcc-1.0.0 directory for complete details on building the application. Below are steps to build the application with the GNU compilers provided with the compute roll on a base installation of Rocks 4.1 i386.

Create a definitions file in the hpl subdirectory of hpcc-1.0.0 named Make.rocks.gnu:

 # cd hpcc-1.0.0/hpl
 # vi Make.rocks.gnu

The contents of Make.rocks.gnu are shown here for a Rocks 4.1 i386 cluster using the default MPICH/GNU/Ethernet mpicc wrapper script:

 SHELL        = /bin/sh
 CD           = cd
 CP           = cp
 LN_S         = ln -s
 MKDIR        = mkdir
 RM           = /bin/rm -f
 TOUCH        = touch
 ARCH         = $(arch)
 TOPdir       = /share/apps/benchmarks/hpcc_bench/hpcc-1.0.0/hpl
 INCdir       = $(TOPdir)/include
 BINdir       = $(TOPdir)/bin/$(ARCH)
 LIBdir       = $(TOPdir)/lib/$(ARCH)
 HPLlib       = $(LIBdir)/libhpl.a
 MPdir        = /opt/mpich/myrinet/gnu
 MPinc        = -I$(MPdir)/include
 MPlib        = -lmpich
 LAdir        = /usr/lib
 LAinc        =
 LAlib        = $(LAdir)/libcblas.a $(LAdir)/libatlas.a
 F2CDEFS      =
 HPL_INCLUDES = -I$(INCdir) -I$(INCdir)/$(ARCH) $(LAinc) $(MPinc)
 HPL_LIBS     = $(HPLlib) $(LAlib) $(MPlib) -lm
 HPL_OPTS     = -DHPL_CALL_CBLAS
 HPL_DEFS     = $(F2CDEFS) $(HPL_OPTS) $(HPL_INCLUDES)
 CC           = /opt/mpich/gnu/bin/mpicc
 CCNOOPT      = $(HPL_DEFS)
 CCFLAGS      = $(HPL_DEFS) -fomit-frame-pointer -O3 -funroll-loops -W -Wall
 LINKER       = $(CC)
 LINKFLAGS    = $(CCFLAGS)
 ARCHIVER     = ar
 ARFLAGS      = r
 RANLIB       = echo

Once you've created the definitions file in the hpl directory, build the application in the hpcc-1.0.0 directory:

 # cd ..
 # make arch=rocks.gnu

Running the benchmark

Please refer to README.txt located in the hpcc-1.0.0 directory for complete details. Outlined below are steps to run the benchmark with the default settings in the input file.

The first step is to copy the example input file to a working version:

 # cp _hpccinf.txt hpccinf.txt
