错误，同时建立NAS基准(Error while building NAS benchmarks)

我想建立使用英特尔MPI NAS基准和下面是我使用的makefile文件。

# Parallel Fortran:
#
# For CG, EP, FT, MG, LU, SP and BT, which are in Fortran, the following must 
# be defined:
#
# MPIF77     - Fortran compiler
# FFLAGS     - Fortran compilation arguments
# FMPI_INC   - any -I arguments required for compiling MPI/Fortran 
# FLINK      - Fortran linker
# FLINKFLAGS - Fortran linker arguments
# FMPI_LIB   - any -L and -l arguments required for linking MPI/Fortran 
# 
# compilations are done with $(MPIF77) $(FMPI_INC) $(FFLAGS) or
#                            $(MPIF77) $(FFLAGS)
# linking is done with       $(FLINK) $(FMPI_LIB) $(FLINKFLAGS)

#---------------------------------------------------------------------------
# This is the fortran compiler used for MPI programs
#---------------------------------------------------------------------------
MPIF77 = gfortran
# This links MPI fortran programs; usually the same as ${MPIF77}
FLINK   = $(MPIF77)

#---------------------------------------------------------------------------
# These macros are passed to the linker to help link with MPI correctly
#---------------------------------------------------------------------------
FMPI_LIB  =  -L/share/apps/intel/impi/5.0.2.044/intel64/lib -lmpi


#---------------------------------------------------------------------------
# These macros are passed to the compiler to help find 'mpif.h'

# Parallel C:
#
# For IS, which is in C, the following must be defined:
#
# MPICC      - C compiler 
# CFLAGS     - C compilation arguments
# CMPI_INC   - any -I arguments required for compiling MPI/C 
# CLINK      - C linker
# CLINKFLAGS - C linker flags
# CMPI_LIB   - any -L and -l arguments required for linking MPI/C 
#
# compilations are done with $(MPICC) $(CMPI_INC) $(CFLAGS) or
#                            $(MPICC) $(CFLAGS)
# linking is done with       $(CLINK) $(CMPI_LIB) $(CLINKFLAGS)
#---------------------------------------------------------------------------

#---------------------------------------------------------------------------
# This is the C compiler used for MPI programs
#---------------------------------------------------------------------------
MPICC = cc
# This links MPI C programs; usually the same as ${MPICC}
CLINK   = $(MPICC)

#---------------------------------------------------------------------------
# These macros are passed to the linker to help link with MPI correctly
#---------------------------------------------------------------------------

#---------------------------------------------------------------------------
# Global *link time* flags. Flags for increasing maximum executable

#---------------------------------------------------------------------------
# MPI dummy library:
#
# Uncomment if you want to use the MPI dummy library supplied by NAS instead 
# of the true message-passing library. The include file redefines several of
# the above macros. It also invokes make in subdirectory MPI_dummy. Make 
# sure that no spaces or tabs precede include.
#---------------------------------------------------------------------------
# include ../config/make.dummy


#---------------------------------------------------------------------------
# Utilities C:
#
# This is the C compiler used to compile C utilities.  Flags required by 
# this compiler go here also; typically there are few flags required; hence 
# there are no separate macros provided for such flags.
#---------------------------------------------------------------------------
CC  = cc -g


#---------------------------------------------------------------------------
# Destination of executables, relative to subdirs of the main directory. . 
#---------------------------------------------------------------------------
BINDIR  = ../bin


#---------------------------------------------------------------------------
# Some machines (e.g. Crays) have 128-bit DOUBLE PRECISION numbers, which
# is twice the precision required for the NPB suite. A compiler flag 
# (e.g. -dp) can usually be used to change DOUBLE PRECISION variables to
# 64 bits, but the MPI library may continue to send 128 bits. Short of
# recompiling MPI, the solution is to use MPI_REAL to send these 64-bit
# numbers, and MPI_COMPLEX to send their complex counterparts. Uncomment
# the following line to enable this substitution. 
# 
# NOTE: IF THE I/O BENCHMARK IS BEING BUILT, WE USE CONVERTFLAG TO
#       SPECIFIY THE FORTRAN RECORD LENGTH UNIT. IT IS A SYSTEM-SPECIFIC
#       VALUE (USUALLY 1 OR 4). UNCOMMENT THE SECOND LINE AND SUBSTITUTE
#       THE CORRECT VALUE FOR "length".
#       IF BOTH 128-BIT DOUBLE PRECISION NUMBERS AND I/O ARE TO BE ENABLED,
#       UNCOMMENT THE THIRD LINE AND SUBSTITUTE THE CORRECT VALUE FOR
#       "length"
#---------------------------------------------------------------------------
# CONVERTFLAG   = -DCONVERTDOUBLE
# CONVERTFLAG   = -DFORTRAN_REC_SIZE=length
# CONVERTFLAG   = -DCONVERTDOUBLE -DFORTRAN_REC_SIZE=length


#---------------------------------------------------------------------------
# The variable RAND controls which random number generator 
# is used. It is described in detail in README.install. 
# Use "randi8" unless there is a reason to use another one. 
# Other allowed values are "randi8_safe", "randdp" and "randdpvec"
#---------------------------------------------------------------------------
RAND   = randi8
# The following is highly reliable but may be slow:
# RAND   = randdp

当我尝试建立假设EP基准使NPROCS = 8 EP CLASS = C，我得到这样一个错误

任何人都可以帮我解决这个问题呢？

Answer 1:

如果您的MPI库英特尔MPI，并且是由英特尔Fortran编译器内置，那么你会很伤心，当您尝试建立与gfortran您的MPI应用程序。

很长一段时间有打电话从C编译器的一些放一个，两个或零下划线上的符号FORTRAN符号的标准方法。

你应该建立NAS与ifort

你也许可以把事情与工作-fno-underscoring选择，但听从以及从gfortran手册页这样的信息：

请注意，仅仅因为名字比赛并不意味着由GNU Fortran的外部名称实现的接口通过一些其他的语言相同名称实现的接口相匹配。即，通过得到的Fortran GNU产生代码链接到通过使用这个或任何其它方法可以是仅整体解决方案的一小部分---得到由两种编译器产生的代码，以在除其他问题同意某些其它编译器产生的代码命名可能需要显著的努力，并且不像命名的分歧，连接器通常不能检测其他领域的分歧。

Answer 2:

看来你的MPI库不会启动。你可以尝试其他的MPI库类似的openmpi。
