OpenFOAM9“加载共享库时出错”

问：

背景信息：

runAirfoil2D.sh

echo "Running simulation with $numberOfSubdomains processes."

executable=/opt/openfoam9/platforms/linux64GccDPInt32Opt/bin/simpleFoam

mpirun --hostfile $machines -np $numberOfSubdomains --display-allocation $executable -parallel

终端错误消息：

mpiuser@master:$FOAM_RUN/tutorials/incompressible/simpleFoam$ ./runAirfoil2D.sh
Running simulation with 8 processes.

Primary job  terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.
# --------------------------------------------------------------------------
# --------------------------------------------------------------------------
mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

Process name: [[434,1],4]
Exit code:    127

我正在为我的教授整理一个集群。有 20 台计算机，每台计算机有 4 个内核，但我现在只在主节点和第一个节点上工作。

似乎每当我使用 4 个子域运行 simpleFoam 时，它都能正常运行，因为它只是在主计算机的 4 个内核上运行。但是当我尝试合并第一个节点（因此 8 个子域）时，它会抛出错误，说它找不到共享对象文件，即使它在那里：

mpiuser@master:$FOAM_RUN/tutorials/incompressible/simpleFoam$ ldd /opt/openfoam9/platforms/linux64GccDPInt32Opt/bin/simpleFoam
linux-vdso.so.1 (0x00007ffe7bd25000)
libmomentumTransportModels.so => /opt/openfoam9/platforms/linux64GccDPInt32Opt/lib/libmomentumTransportModels.so (0x00007f18b8600000)

and so on....

我有一个使用 openMPI 和 NFS 的 hello world 脚本，所以我知道我的连接和挂载是正确的。

我哪里出错了？
