Question

我有一个使用OpenMPI进行并行计算的Fortran代码。两周前我运行代码时，情况进展顺利。但今天我有这个奇怪的错误：

mpif90 ./nrutil.f90 ./matrix.f90 ./probability.f90 ./random.f90 ./ardiscret.f90 
./trans_ind_sub.f90 ./globvar.f90 ./interpolpr.f90 ./viterch.f90 ./viterpr.f90 
./bisearch.f90 ./simulate.f90 ./statistics.f90   ./moment.f90 ./main.f90    
-g -o output.out  
/usr/bin/ld: warning: libibverbs.so.1, needed by /home/wenya/.openmpi/lib/libmpi.so, not found (try using -rpath or -rpath-link)
/home/wenya/.openmpi/lib/libmpi.so: undefined reference to  `ibv_read_sysfs_file@IBVERBS_1.0'
/home/wenya/.openmpi/lib/libmpi.so: undefined reference to  `ibv_register_driver@IBVERBS_1.1'
collect2: error: ld returned 1 exit status
Makefile:32: recipe for target 'output' failed
make: *** [output] Error 1

这是我的makefile：

#Compiler
fc = mpif90
#Compiler flags
FCFLAGS= -fcheck=all

SRCS= ./nrutil.f90  \
    ./matrix.f90 \
    ./probability.f90 \
    ./random.f90 \
    ./ardiscret.f90  \
    ./trans_ind_sub.f90 \
    ./globvar.f90 \
    ./interpolpr.f90 \
    ./viterch.f90\
    ./viterpr.f90 \
    ./bisearch.f90\
    ./simulate.f90 \
    ./statistics.f90 \
    ./moment.f90 \
    ./main.f90 \
output:
    $(fc) $(SRCS) -g -o output.out $(LFLAGS) $(LIBS)
debug:
    $(fc) $(SRCS) -g -o debug.exe
clean:
    rm -rf *.mod *.o *.il *~ \#* PI*

run:
   mpirun -np 8 ./output.out

我的操作系统：Ubuntu 16.04.2; GNU Fortran：5.4.0。我想知道OpenMPI安装是否有任何问题。当我输入ompi_info以获取OpenMPI版本号时，我得到了

ompi_info: error while loading shared libraries: libibverbs.so.1: cannot open shared object file: No such file or directory

这在某种程度上是愚蠢的，因为该计划在两周前顺利进行。有什么想法吗？

使用OpenMPI编译Fortran代码时缺少libibverbs.so.1
