在另一台计算机中加载共享库时发生MPI错误：libpgftnrtl.so

我内置了一台linux（ubuntu）机器（SOL），在这台机器上运行正常。只有SOL拥有所有编译器LIB

./mpiexec -n 8 -f machinefile /usr/apps/lib/mpich-3.3.2-pgf_gcc/examples/cpi
Process 0 of 8 is on SOL
Process 6 of 8 is on SOL
Process 1 of 8 is on SOL
Process 7 of 8 is on SOL
Process 3 of 8 is on SOL
Process 2 of 8 is on SOL
Process 4 of 8 is on SOL
Process 5 of 8 is on SOL
pi is approximately 3.1415926544231247, Error is 0.0000000008333316
wall clock time = 0.001447

机器文件

SOL: 8

SOL: 4
Corona:4

然而，当我尝试在两台机器上运行MPI时 机器文件

SOL: 8

SOL: 4
Corona:4

Corona找不到所需的lib

如何解决此问题？

缺少的文件来自PGI编译器运行时。您需要将它安装在

Corona

的本地磁盘上，或者从该节点上的共享文件系统装载它

ssh-SOL-ldd/usr/apps/lib/mpich-3.3.2-pgf_-gcc/examples/cpi | grep-libpgftnrtl.so

将向您显示此文件在

SOL

上的位置。我想知道我应该静态编译mpi吗<代码>shell$./configure--不带内存管理器--不带libnuma \--启用静态[…其他配置参数…]否。但您可能想尝试链接静态PGI运行时（英特尔有一个标志，不知道PGI）
