IOR and mdtest - measure parallel file system I/O performance at both the POSIX and MPI-IO level.

This parallel program performs writes and reads to/from files under several sets of conditions and reports the resulting throughput rates. 

IOR 设计用于测量POSIX和MPI-IO级别的并行文件系统的I/O的性能;mdtest 被设计用于测试文件系统的元数据性能并生成测试报告;

mdtest 工具已经变成了ior 工具的一部分了。我们可以安装ior套件,并使用 其中mdtest命令来进行测试文件系统元数据的性能;该工具由美国洛斯阿拉莫斯国家实验室(Los Alamos National Laboratory)开发并开源,具有较高的权威性;

安装说明:

  1. If configure is missing from the top level directory, you probably retrieved this code directly from the repository. Run ./bootstrap to generate the configure script. Alternatively, download an official IOR release which includes the configure script.

  2. Run ./configure. For a full list of configuration options, use ./configure --help.

  3. Run make

  4. Optionally, run make install. The installation prefix can be changed via ./configure --prefix=... 

  5. fedora 系统 需要安装 openmpi 和 openmpi-devel rpm 包来进行配置环境并记得在 .bash_profile 中进行配置环境变量;具体环境变量配置如下列截图所示:
