面向英特尔® Parallel Studio XE 集群版的无密码 SSH 安装

我在我的集群中建立了一个安全的 shell (SSH) 连接,其中每个节点都有一个公共密钥。 但是,当我在集群上使用安全的 shell 实用程序时,系统还是提示我输入密码。 哪里出问题了?

使用 ssh-keygen 实用程序时,假设您针对登录账户以及集群中的所有系统设置了 NULL “ 密码”,并且将每个节点的公共密钥分配给所有其他节点(即位于 “ ~/.ssh/authorized_keys” 文件中的公共密钥),那么请检查集群上主目录的权限。 “group” 和 “other” 权限类别仅具备针对主目录文件夹的读取和执行权限。 如果您为“group” 或 “other” 类别激活写权限,SSH 将提示您输入密码。 此外,登录者对于 “ ~/.ssh” 子目录只有读、写和执行权限。

请注意,expect shell 脚本 sshconnectivity.exp 将会移除该组的写入访问权限,以及用户主目录文件夹的其它“权限类别”。

    I wish to use Intel MPI benchmarks for performance analysis of my mpich2 implementation. However, I'm using mpich2-1.4.1 version in my cluster. Where can I download the appropriate benchmarks for this version of mpich2? The latest version is not compatible with the mpich2 version I use.

    Please help.

  • Ordering of images on different nodes using Coarray Fortran and IntelMPI

    Hello

    I have a question about ordering of images when -coarray=distributed compiler option is used and the program is run on a cluster using IntelMPI libraries.

    Assuming that the number of images is the same as the number of CPUs, are the images running on CPUs within the same node indexed by consecutive numbers?
