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:

    Tips and Tricks to Optimize Android Apps on x86

    Intel has a vested interest in helping developers provide Android applications that run well (or even best) on Intel architecture. While Intel is working at the community level - optimizing Dalvik Java, V8 engine, and Bionic C; contributing to the code base; and providing releases with both 32 bit and 64-bit Kernels for IA; they are also creating new tools to help  Android developers. Many of these focus on improving performance beyond that available with the default ARM translation layer for x86: libhoudini

    Incompatibility between the Intel® MPI Library and certain versions of the Mellanox* OFED drivers

    Cause

    There is an incompatibility between the Intel® MPI Library and some versions of the Mellanox* OFED drivers when using the DAPL* fabric.  This has been reported with Mellanox* OFED 2.1-1.0.0, and could exist in other versions.

    Symptoms

    You will likely see Segmentation Faults in MPI_Init when running.  A stack trace could show:
