Getting Started with the MPI Performance Snapshot

The MPI Performance Snapshot (MPS) is a scalable lightweight performance tool for MPI applications. It collects a variety of MPI application statistics (such as communication, activity, and load balance) and presents it in an easy-to-read format. The tool is not available separately but is provided as part of the Intel® Trace Analyzer and Collector installation.  This article will serve as a quick getting started guide.

    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”。

  • Explicit offload for Quantum ESPRESSO

    Purpose

    This code recipe describes how to get, build, and use the Quantum ESPRESSO code that includes support for the Intel® Xeon Phi™ coprocessor with Intel® Many-Integrated Core (MIC) architecture. This recipe focuses on how to run this code using explicit offload.

  • Passwordless SSH install for Intel® Parallel Studio XE Cluster Edition

    I have established secure shell (SSH) connectivity on my cluster where each node has a public key. However, when I use any secure shell utility on the cluster, I am still prompted for a password. What am I doing wrong?
