Environment variables 在Vampirtrace中生成跟踪文件时出错

mpi

Environment variables 在Vampirtrace中生成跟踪文件时出错,environment-variables,mpi,openmp,openmpi,Environment Variables,Mpi,Openmp,Openmpi,我想对我使用OpenMPI库编写的并行处理代码进行评测。我正试图用吸血鬼赛跑来达到这个目的。我使用命令编译代码 vtcxx -vt:cxx mpic++ ../src/parallel_encode_nonBlocking.cpp -o parallel_encode_nonBlocking_trace.exe 我试图用下面的命令运行我的代码来生成跟踪文件 mpirun -np 4 parallel_encode_nonBlocking_trace.exe ducks.m2v ducks11

我想对我使用OpenMPI库编写的并行处理代码进行评测。我正试图用吸血鬼赛跑来达到这个目的。我使用命令编译代码

vtcxx -vt:cxx mpic++ ../src/parallel_encode_nonBlocking.cpp -o parallel_encode_nonBlocking_trace.exe

我试图用下面的命令运行我的代码来生成跟踪文件

mpirun -np 4 parallel_encode_nonBlocking_trace.exe  ducks.m2v ducks11.h264

最后两个名称是代码所需的输入和输出文件的名称。但在运行代码后，我会出现以下错误

中似乎有一个bug，应用程序二进制文件的绝对路径名中有空格。要解决这个问题，您可以从“Harshad MTP”目录中删除空间，或者手动执行

nm parallel_encode_nonBlocking_trace.exe > nm.file
export VT_GNU_NMFILE="$PWD/nm.file"

如果你仔细阅读，错误信息是非常清楚的。
