按照https://help.ubuntu.com/community/MpichCluster 搭了个简单的计算集群，能够跨节点运行mpi_hello程序，但是除了node00能够争取读取.bashrc下的 /home/cluster/HiFiLES-solver外，其余节点不能正确读取。
详细输出可见下面
cluster@node00:~/work$ mpirun -hostfile myhostfile ./mpi_hello
I am Process 1 of 8 on node00
The current path is: /home/cluster/HiFiLES-solver
I am Process 0 of 8 on node00
The current path is: /home/cluster/HiFiLES-solver
I am Process 5 of 8 on node02
The current path is: (null)
I am Process 7 of 8 on node02
The current path is: (null)
I am Process 2 of 8 on node01
The current path is: (null)
I am Process 6 of 8 on node02
The current path is: (null)
I am Process 3 of 8 on node01
The current path is: (null)
I am Process 4 of 8 on node01
The current path is: (null)
代码可见下方
#include
#include / getenv /
#include
int main(int argc, char* argv) {
int myrank, nprocs, namelen;
char processor_name[MPI_MAX_PROCESSOR_NAME];
const char* HIFILES_DIR;
MPI_Init(&argc, &argv);
MPI_Comm_size(MPI_COMM_WORLD, &nprocs);
MPI_Comm_rank(MPI_COMM_WORLD, &myrank);
MPI_Get_processor_name(processor_name, &namelen);
printf("I am Process %d of %d on %s\n", myrank, nprocs, processor_name);
HIFILES_DIR = getenv ("HIFILES_HOME");
printf ("The current path is: %s\n", HIFILES_DIR);
MPI_Finalize();
return 0;
}
不知道是怎么回事儿？
