Intel® Cluster Toolkit

Using Intel® MPI Library 5.0 with MPICH based applications

Why it is needed?

Different MPI implementations have their specific benefits and advantages. So in the specific cluster environment the HPC application with the other MPI implementation can probably perform better.

 Intel® MPI Library has the following benefits:

  • 更好地解决使用Intel® Xeon Phi™时可能的内存空间不足的问题

      1.超出内存空间

    Intel® Xeon Phi™协处理器上的Linux操作系统跟其它任何Linux*操作系统一样,会允许用户分配大于物理可用的内存空间,在很多系统中这是由交换一些内存页到磁盘的方式来实现,并且当可用的物理内存加上交换空间的总量大于一个上限值时,操作系统将会开始关掉某些进程。

    Intel® Xeon Phi™协处理器上由于缺少直接相连的磁盘使得这种换页机制较难实现,并且:

    • 协处理器上有最大8GB的物理内存可用;
    • 其中一些内存被缺省用来存放协处理器的文件系统;
    • 没有交换空间可供协处理器来换页

      2.限制虚拟内存盘的内存使用

    由于协处理器上没有直接可存取的磁盘,所以协处理器上缺省的根文件系统存放在虚拟内存盘中,这导致不仅减少了文件的存储空间也降低了可供程序运行时使用的内存空间。

    根文件系统可通过裁剪而变得较小,如使用BusyBox来取代很多常用的Linux命令比如sh,cp及ls等以及通过限制拷贝到文件系统中的共享库数量来控制文件系统整体的占用空间,一般来说,裁剪后的可供Intel® Xeon Phi™协处理器使用的根文件系统至少要占用10MB的运行时内存。

  • Submissions open: High Performance Parallelism Gems

    We have all had our little discoveries and triumphs in identifying new and innovative approaches that increased the performance of our applications. Occasionally we find something more, something that could also help others, an innovative gem. You now have an opportunity to broadcast your successes more widely to the benefit of our community. You are invited to submit a proposal to a contribution-based book, working title, “High Performance Parallelism Gems – Successful Approaches for Multicore and Many-core Programming” that will focus on practical techniques for Intel® Xeon® processor and Intel® Xeon Phi™ coprocessor parallel computing. Submissions are due by May 29, 2014.

    Intel® Cluster Studio XE works on Xeon® Phi coprocessor? OpenMP*? TBB? MPI?
