在采用英特尔® 至强融核™ 协处理器的系统上配置 Mellanox* InfiniBand 适配器

InfiniBand* 是 HPC 区域中经常使用的网络通信协议,因为该协议可以提供非常高的吞吐量。 英特尔和 Mellanox* 是最受欢迎的 InfiniBand* 适配器生产商。 在本博客中,我将介绍如何使用三个版本的 OFED* (Open Fabrics Enterprise Distribution) — OpenFabrics OFED-1.5.4.1、OpenFabrics OFED-3.5.2-mic 和 Mellanox* OFED 2.1 在采用英特尔® 至强融核™ 协处理器的系统上安装和测试 Mellanox* InfiniBand* 适配器卡。

为了允许协处理器上的原生应用与 Mellanox* InfiniBand 适配器进行通信,必须启用协处理器通信链路 (CCL)。 当使用 Mellanox* InfiniBand 适配器时,上面提到的三种 OFED 堆栈支持 CCL。

1. 硬件安装

使用两种系统,每种系统配备一台英特尔® 至强™ E5-2670 2.60 GHz 处理器和两台英特尔® 至强融核™ 协处理器。 两个系统都运行 RHEL 6.3。 它们使用千兆以太网适配器并通过千兆以太网路由器进行连接。

Compiling, Configuring and running Lustre on Intel® Xeon Phi™ Coprocessor

This article enumerates the recommended steps to enable Lustre on the Intel® Xeon Phi™ coprocessor. The steps in this document are validated against the Intel® Manycore Platform Software Stack (Intel® MPSS) versions 3.3.x and 3.4.x and with Lustre versions 2.5.x and 2.6.0.

Working with Mellanox* InfiniBand Adapter on System with Intel® Xeon Phi™ Coprocessors

InfiniBand* is a network communications protocol commonly used in the HPC area because the protocol offers very high throughput. Intel and Mellanox* are among the most popular InfiniBand* adapter manufacturers. In this blog, I will share my experience of installing and testing Mellanox* InfiniBand* adapter cards with three different versions of OFED* (Open Fabrics Enterprise Distribution), OpenFabrics OFED-1.5.4.1, OpenFabrics OFED-3.5.2-mic and Mellanox* OFED 2.1, on systems containing Intel® Xeon Phi™ coprocessors.

Intel® Cluster Ready Architecture Specification version 1.3.1 Summary

The Intel® Cluster Ready architecture specification version 1.3.1 has officially released as of July 2014.  This is a minor update from version 1.3 with most of the changes between the versions are related to the following:

  • removal of library or tool requirements based on analysis of Intel® Cluster Ready registered applications
  • updated/refreshed required versions of key libraries and tools

Details of the updates to the architecture requirements:

  • Troubleshooting OFED* for Use with the Intel® MPSS

    This is a list of what are hopefully helpful hints for troubleshooting problems with OFED* and InfiniBand* when used with the Intel® Xeon Phi™ coprocessor.

    1) Finding Documentation

    The primary sources for information on OFED for the Intel Xeon Phi coprocessor are:

    Symmetric Mode MPI Performance without InfiniBand*

    Symptom

    Slow host-coprocessor MPI communications in systems with no InfiniBand* HCA.  If running with I_MPI_DEBUG=2 or higher, you will see one of the following messages indicating that the TCP fabric has been selected:

    [0] MPI startup(): tcp data transfer mode
    [0] MPI startup(): shm and tcp data transfer modes
