HBM for the Intel® Xeon Phi™ Coprocessor

Purpose

This article provides instructions for code access, build, and run directions for the Baffin-Bay test cases for the HBM code, running on Intel® Xeon® processors and Intel® Xeon Phi™ Coprocessors.

Introduction

Danish Meteorological Institute (DMI) operates a regional 3D ocean model HBM for the North Sea - Baltic, in order to provide information about the physical state of the Danish and nearby waters in the near future.

  • Hydra Incompatibility with Certain gdb* Versions

    There is a known compatibility problem between Hydra and versions 7.2 and 7.3 of the GNU* Debugger (gdb*).  When running Hydra under one of these versions, Hydra will hang.

    Please use a different version of gdb in order to run Hydra under gdb.

    This has only been seen in Linux* at this time.

  • Compiler Wrapper Scripts Returning 0 Incorrectly

    There is currently a known issue in the Intel® MPI Library for Linux*, affecting Version 5.0 and Version 5.0 Update 1.  The compiler wrapper scripts will always return 0, even if the compile or link failed.  This can lead to errors in makefiles or any job checking the return code.  The error is corrected and a fix is available in Version 5.0 Update 2.

    There are currently three workarounds for this issue:

  • Intel Software Tools Technical Webinar Series

    These free technical webinars cover tips and techniques that will help sharpen your development skills to create faster, more reliable applications. Technical experts will cover topics ranging from vectorization, code migration, code optimization, using advanced threading techniques (e.g., OpenMP 4.0, Intel® Cilk™ Plus, Intel® TBB), and error checking. Bring programming questions to the live session for our technical experts to answer. A replay of each webinar will be available shortly after the live session so you can share with those unable to attend the live session.

    Introducing Intel® MPI Library 

    The Intel® MPI Library is a multi-fabric message passing library that implements the Message Passing Interface, v3.0 (MPI-3.0) specification. It provides a standard library across Intel® platforms that enable adoption of MPI-3.0 functions as their needs dictate.

    Local Options 

    -n <# of processes> or -np <# of processes> 

    Use this option to set the number of MPI processes to run with the current argument set.
