最新的Linpack测试指南－基于woodcrest机器

本次基于一台1个CPU的woodcrest 1.86GHz的机器，2G内存

1、BLAS用GotoBLAS，目前最新是1.10版，解开，然后编辑Makefile.rule，如下（这里没有列出的部分就是我没有修改的部分）：

#
# Beginning of user configuration
#

# This library's version
REVISION = -r1.10

# Which do you prefer to use for C compiler? Default is gcc.
# I recommend you to use GCC because inline assembler is required.
C_COMPILER = GNU
# C_COMPILER = INTEL

# Which do you prefer to use for Fortran compiler? Default is GNU g77.
F_COMPILER = G77
# F_COMPILER = G95
# F_COMPILER = GFORTRAN
# F_COMPILER = INTEL
# F_COMPILER = PGI
# F_COMPILER = PATHSCALE
# F_COMPILER = IBM
# F_COMPILER = COMPAQ
# F_COMPILER = SUN
# F_COMPILER = F2C

# If you need 64bit binary; some architecture can accept both 32bit and
# 64bit binary(EM64T, Opteron, SPARC and Power/PowerPC).
BINARY64 = 1

# If you want to build threaded version.
# You can specify number of threads by environment value
# "OMP_NUM_THREADS", otherwise, it's automatically detected.
SMP = 1

# You may specify Maximum number of threads. It should be minimum.
# For OpenMP users; you have to specify MAX_THREADS even if you don't
# use threaded BLAS(MAX_THREADS >= OMP_NUM_THREADS * GOTO_NUM_THREADS)
MAX_THREADS = 2

2、注意，上面编译器部分可以根据自己的需要修改，比如装了Intel的编译器就改成Intel编译器；另外，BINARY64=1这个选项要打 开，如果安装了x86-64的操作系统的话，否则HPL在编译的时候就会报告说libgoto不是一个x86-64的库，虽然最终xhpl能生成，但是运 行的时候会出错

OK, 输入make就大功告成了

3、解开HPL的包，然后 cp setup/Make.Linux_PII_FBLAS Make.wc（表示arch是wc），然后编辑Make.wc，修改成这样：

# ----------------------------------------------------------------------
# - shell --------------------------------------------------------------
# ----------------------------------------------------------------------
#
SHELL = /bin/sh
#
CD = cd
CP = cp
LN_S = ln -s
MKDIR = mkdir
RM = /bin/rm -f
TOUCH = touch
#
# ----------------------------------------------------------------------
# - Platform identifier ------------------------------------------------
# ----------------------------------------------------------------------
#
ARCH = wc
#
# ----------------------------------------------------------------------
# - HPL Directory Structure / HPL library ------------------------------
# ----------------------------------------------------------------------
#
TOPdir = $(HOME)/hpl
INCdir = $(TOPdir)/include
BINdir = $(TOPdir)/bin/$(ARCH)
LIBdir = $(TOPdir)/lib/$(ARCH)
#
HPLlib = $(LIBdir)/libhpl.a
#
# ----------------------------------------------------------------------
# - Message Passing library (MPI) --------------------------------------
# ----------------------------------------------------------------------
# MPinc tells the C compiler where to find the Message Passing library
# header files, MPlib is defined to be the name of the library to be
# used. The variable MPdir is only used for defining MPinc and MPlib.
#
MPdir = /usr/local/mpich
MPinc = -I$(MPdir)/include
MPlib = $(MPdir)/lib/libmpich.a
#
# ----------------------------------------------------------------------
# - Linear Algebra library (BLAS or VSIPL) -----------------------------
# ----------------------------------------------------------------------
# LAinc tells the C compiler where to find the Linear Algebra library
# header files, LAlib is defined to be the name of the library to be
# used. The variable LAdir is only used for defining LAinc and LAlib.
#
LAdir = $(HOME)/GotoBLAS
LAinc =
LAlib = $(LAdir)/libgoto.a
#
# ----------------------------------------------------------------------
# - F77 / C interface --------------------------------------------------
# ----------------------------------------------------------------------
# You can skip this section if and only if you are not planning to use
# a BLAS library featuring a Fortran 77 interface. Otherwise, it is
# necessary to fill out the F2CDEFS variable with the appropriate
# options. **One and only one** option should be chosen in **each** of
# the 3 following categories:
#
# 1) name space (How C calls a Fortran 77 routine)
#
# -DAdd_ : all lower case and a suffixed underscore (Suns,
# Intel, ...), [default]
# -DNoChange : all lower case (IBM RS6000),
# -DUpCase : all upper case (Cray),
# -DAdd__ : the FORTRAN compiler in use is f2c.
#
# 2) C and Fortran 77 integer mapping
#
# -DF77_INTEGER=int : Fortran 77 INTEGER is a C int, [default]
# -DF77_INTEGER=long : Fortran 77 INTEGER is a C long,
# -DF77_INTEGER=short : Fortran 77 INTEGER is a C short.
#
# 3) Fortran 77 string handling
#
# -DStringSunStyle : The string address is passed at the string loca-
# tion on the stack, and the string length is then
# passed as an F77_INTEGER after all explicit
# stack arguments, [default]
# -DStringStructPtr : The address of a structure is passed by a
# Fortran 77 string, and the structure is of the
# form: struct {char *cp; F77_INTEGER len;},
# -DStringStructVal : A structure is passed by value for each Fortran
# 77 string, and the structure is of the form:
# struct {char *cp; F77_INTEGER len;},
# -DStringCrayStyle : Special option for Cray machines, which uses
# Cray fcd (fortran character descriptor) for
# interoperation.
#
F2CDEFS = -DAdd__ -DF77_INTEGER=int -DStringSunStyle
#
# ----------------------------------------------------------------------
# - HPL includes / libraries / specifics -------------------------------
# ----------------------------------------------------------------------
#
HPL_INCLUDES = -I$(INCdir) -I$(INCdir)/$(ARCH) $(LAinc) $(MPinc)
HPL_LIBS = $(HPLlib) $(LAlib) $(MPlib)
#
# - Compile time options -----------------------------------------------
#
# -DHPL_COPY_L force the copy of the panel L before bcast;
# -DHPL_CALL_CBLAS call the cblas interface;
# -DHPL_CALL_VSIPL call the vsip library;
# -DHPL_DETAILED_TIMING enable detailed timers;
#
# By default HPL will:
# *) not copy L before broadcast,
# *) call the BLAS Fortran 77 interface,
# *) not display detailed timing information.
#
HPL_OPTS =
#
# ----------------------------------------------------------------------
#
HPL_DEFS = $(F2CDEFS) $(HPL_OPTS) $(HPL_INCLUDES)
#
# ----------------------------------------------------------------------
# - Compilers / linkers - Optimization flags ---------------------------
# ----------------------------------------------------------------------
#
CC = /usr/local/mpich/bin/mpicc
CCNOOPT = $(HPL_DEFS)
CCFLAGS = $(HPL_DEFS) -fomit-frame-pointer -O3 -funroll-loops -W -Wall
#
# On some platforms, it is necessary to use the Fortran linker to find
# the Fortran internals used in the BLAS library.
#
LINKER = /usr/local/mpich/bin/mpif77
LINKFLAGS = $(CCFLAGS)
#
ARCHIVER = ar
ARFLAGS = r
RANLIB = echo
#
# ----------------------------------------------------------------------

4、很简单，基本上就需要指定hpl、libgoto.a和mpich的位置就OK了，最后链接用mpif77，编译用mpicc即可。输入make arch=wc就OK了，编译失败的话，用make arch=wc clean就可以删除make的痕迹

5、然后就是修改HPL.dat，run xhpl了。 HPL.dat已经说了很多次了，不说了

 

本次使用了xxx集群上的HPL.dat设置，跑出来的结果是12.15GFlops，理论峰值是14.88GFlops（1颗CPU），效率是81.65%
