Question

我正在尝试运行使用英特尔编译器编译的程序。该程序具有openMP和MPI代码。 MPI代码是该程序的新增功能。

使用gcc编译的代码和OpenMPI（gcc-flavored，v1.8）运行正常。
使用“地址未映射”错误编译icpc和Intel编译的OpenMPI seg错误的代码

OpenMPI（使用英特尔编译）错误

[ida3c03:22018] 63 more processes have sent help message help-mpi-btl-openib.txt / reg mem limit low
[ida3c03:22018] Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error messages
done!
[ida3c04:03329] *** Process received signal ***

[ida3c04:03329] Signal code: Address not mapped (1)
[ida3c04:03329] Failing at address: 0x10

使用icpc编译的代码和Intel自己的MPI seg错误以及2个错误之一

错误1

这个项目很庞大，很难向你展示所有的MPI代码，但我从其中一个主要文件中搜出了MPI调用，我认为这个错误发生了，以防万一有用。我用“vector _＃”填充了实际的变量名。

1172:  MPI_Init(&argc,&argv);
1173:  MPI_Comm_size(MPI_COMM_WORLD, &numranks);
1174:  MPI_Comm_rank(MPI_COMM_WORLD,&rank);
1315:  MPI_Barrier(MPI_COMM_WORLD);
1593:  MPI_Allgather(&long_1,1,MPI_LONG,vector_1,1,MPI_LONG,MPI_COMM_WORLD);
1594:  MPI_Allgather(&long_2, 1,MPI_LONG,vector_2, 1,MPI_LONG,MPI_COMM_WORLD);    
1624:  MPI_Barrier(MPI_COMM_WORLD);
1655:  MPI_Bcast(buffer,long*[count],MPI_CHAR,count,MPI_COMM_WORLD);
1661:  MPI_Allgatherv(dnas_chars_send, long_2, MPI_CHAR,  char*,int*, long*, MPI_CHAR,MPI_COMM_WORLD);
1740:  MPI_Barrier(MPI_COMM_WORLD);
2013:  MPI_Barrier(MPI_COMM_WORLD); 
2064:  MPI_Allgather(&int,1,MPI_INT,int*,1,MPI_INT,MPI_COMM_WORLD);
2066:  MPI_Allgather(&int,1,MPI_INT,int*,1,MPI_INT,MPI_COMM_WORLD);
2068:  MPI_Allgather(&int,1,MPI_INT,int*,1,MPI_INT,MPI_COMM_WORLD);
2106:  MPI_Allgatherv(int*, int,MPI_INT,int* ,int*, int*, MPI_INT,MPI_COMM_WORLD);
2107:  MPI_Allgatherv(int*, int,MPI_INT,int* ,int*, int*, MPI_INT,MPI_COMM_WORLD);
2108:  MPI_Allgatherv(int*,int,MPI_INT,int*,int*,int*, MPI_INT,MPI_COMM_WORLD);
2136:  MPI_Allgatherv(int*,int,MPI_INT,int*,int*,int*, MPI_INT,MPI_COMM_WORLD);
2137:  MPI_Allgatherv(int*,int,MPI_INT,int*,int*,int*, MPI_INT,MPI_COMM_WORLD);
2164:  MPI_Barrier(MPI_COMM_WORLD);
2519:  MPI_Finalize();

但是我不明白为什么代码在gcc中没问题，然后为icpc遇到这个错误。代码在群集上运行，我无权访问MPI进程正在运行的后端节点。

与icpc相关的MPI相关分段错误但不是GCC
