Ошибка при построении тестов NAS

Я пытаюсь создать тесты NAS с использованием Intel MPI, и ниже приведен make-файл, который я использую.

# MPIF77     - Fortran compiler
# FFLAGS     - Fortran compilation arguments
# FMPI_INC   - any -I arguments required for compiling MPI/Fortran 
# FLINK      - Fortran linker

#

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

#
# 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

Когда я пытаюсь построить, скажем, тест EP make NPROCS=8 EP CLASS=C, я получаю сообщение об ошибке, например

Может ли кто-нибудь помочь мне в решении этой проблемы?

Если ваша библиотека MPI представляет собой Intel MPI и была собрана компилятором intel fortran, то вам будет грустно, когда вы попытаетесь собрать свое приложение MPI с помощью gfortran.

Долгое время не существовало стандартного способа вызова символов фортрана из C. Некоторые компиляторы ставили перед символом один, два или ноль подчеркиваний.

Вы должны построить NAS с ifort

Вы можете заставить все работать с опцией -fno-underscoring , но обратите внимание на это сообщение со страницы руководства gfortran:

Обратите внимание, что только то, что имена совпадают, не означает, что интерфейс, реализованный GNU Fortran для внешнего имени, соответствует интерфейсу, реализованному каким-либо другим языком для того же имени. То есть получение кода, созданного GNU Fortran, для ссылки на код, созданный каким-либо другим компилятором с использованием этого или любого другого метода, может быть лишь небольшой частью общего решения — получение кода, созданного обоими компиляторами, для согласования вопросов, кроме именование может потребовать значительных усилий, и, в отличие от разногласий в именах, компоновщики обычно не могут обнаружить разногласия в этих других областях.

Похоже, у вас не запускается библиотека mpi. Вы можете попробовать другую библиотеку mpi, например openmpi.
