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:

    The Intel® MPI Library provides an automatic tuning utility to help you select optimal values for many environment variables that can be used to influence program behavior and performance at run time.
