我一直在努力让并行 HDF5 在集群上工作整整一周，但没有任何进展。我希望是否有人可以帮助我解决这个问题。谢谢！
我正在使用 RedHat Enterprise Linux 5.5 x86_64 操作系统在光泽文件系统上构建 Parallel HDF5 (hdf5-1.8.15-patch1)。我尝试用 impi 4.0.2 和 openmpi 1.8 编译它，它成功了，没有任何错误。当我“进行检查”时，它们都通过了串行测试，但在进入并行测试后立即挂起（特别是 t_mpi）。最终，我不得不按 ctrl+C 来结束它。这是输出：

Parallel test files reside in the current directory by default.

上面两个 MPI 实现的输出是一样的，但是 openmpi 也会输出警告：
警告：您的 OpenFabrics 子系统似乎配置为仅允许注册您的部分物理内存。这可能会导致 MPI 作业以不稳定的性能运行、挂起和/或崩溃。
我已经搜索过这个问题。但我不认为这可能是挂起的原因，原因在最后说明。
我试图找到它挂起的地方。我发现它总是卡在它遇到的第一个集体功能上。例如，在 t_mpi. 它首先挂在：
MPI_File_delete（文件名，MPI_INFO_NULL）；（第 477 行），
在 test_mpio_1w 先生。如果我注释掉这一行，它就会卡在下面的 MPI_File_open 上。但我不确定这些函数内部发生了什么。
我注意到另一件事。我进行“制作”的 HDF5 文件夹位于 NFS 文件系统中，我只能通过位于其他地方的特定文件夹访问光泽。所以，我发现如果我不将 HDF5_PARAPERFIX 设置为我的 luster 文件夹，测试运行得很好，因为默认情况下测试是在本地执行的。所以，我想这应该是与光泽本身有关的问题，而不是内存的限制？
谢谢！
