Грешка при изграждането на NAS бенчмаркове

Опитвам се да създам тестове за NAS с помощта на Intel MPI и по-долу е makefile-ът, който използвам.

# FMPI_INC   - any -I arguments required for compiling MPI/Fortran 
# FLINK      - Fortran linker

#
# compilations are done with $(MPICC) $(CMPI_INC) $(CFLAGS) or
#                            $(MPICC) $(CFLAGS)

# 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

Ако вашата MPI библиотека е Intel MPI и е създадена от компилатора на intel fortran, тогава ще бъдете тъжни, когато се опитате да изградите вашето MPI приложение с gfortran.

Дълго време нямаше стандартен начин за извикване на fortran символи от C. Някои компилатори поставят една, две или нула долна черта върху символа.

Трябва да изградите NAS с ifort

Вие може да успеете да накарате нещата да работят с опцията -fno-underscoring, но обърнете внимание на това съобщение от страницата на gfortran man:

Обърнете внимание, че само защото имената съвпадат, не означава, че интерфейсът, реализиран от GNU Fortran за външно име, съвпада с интерфейса, реализиран от друг език за същото име. Това означава, че получаването на код, произведен от GNU Fortran, за да се свърже с код, произведен от друг компилатор, използващ този или който и да е друг метод, може да бъде само малка част от цялостното решение --- да накарате кода, генериран от двата компилатора, да се съгласи по въпроси, различни от именуването може да изисква значителни усилия и, за разлика от несъгласията при именуване, линкерите обикновено не могат да открият несъгласия в тези други области.

Изглежда, че вашата mpi библиотека не стартира. Можете да опитате друга mpi библиотека като openmpi.
