Mensagens de erro e de diagnóstico

Баги и фичи

Уважаемые читатели и авторы русскоязычных блогов Сообщества Разработчиков Intel, с сентября 2012 года блоги работают на новой площадке - Intel Developer Zone (IDZ), используют новый "движок", дают новые возможности, и, к сожалению,.... новые баги. Так, в течение нескольких недель вместо русскоязычных блогов на соответствующей странице IDZ отображались блоги на английском языке, а RSS-подписчикам однажды даже довелось получить посты на китайском языке. Существуют проблемы и с отображением блогов и с их созданием. Хотя их число постепенно и неуклонно уменьшается, но пока оно больше нуля.

"Illegal instructions" errors for some Intel® IPP functions

Symptom:
Some Intel(R) IPP functions may report "illegal instructions” errors on the Intel® AVX-512 processor systems running with Windows* 7 Service Pack 1 (SP1) OS.  The problem only happens with such specific systems.


Reason:
The problem is caused by the incorrect code dispatching for that specific systems. Intel® IPP dispatched the Intel® AVX-512 optimization code, which is not supported by that OS.

  • Intel® Distribution for Python* Known Issues

    Intel Distribution for Python 2018.0.0

    Conda Update says 2017.0.3 is the latest

    Starting from an existing Intel(R) Distribution for Python (IDP) 3.5.x conda environment, issuing the "conda update" command does not update the environment to IDP 2018.0.0. It only says "All requested packages already installed."

    Solution: Use "conda install python=3.6 -c intel" instead

  • Diagnostic 15415 vectorization support: gather was generated for the variable a: indirect access

    Product Version: Intel® Fortran Compiler 15.0 and a later version 

    Cause:

    A vectorizable loop contains loads from memory locations that are not contiguous in memory (sometimes known as a “gather”). These may be indexed loads, as in the example below, or loads with non-unit stride. The compiler has issued a hardware gather instruction for these loads.

    (Note that for compiler versions 16.0.1 and earlier, the compiler may also emit this message when gather operations are emulated in software).

  • Diagnostic 15328 vectorization support: gather was emulated for the variable a: indirect access

    Product Version: Intel® Fortran Compiler 15.0 and a later version 

    Cause:

    A vectorizable loop contains loads from memory locations that are not contiguous in memory (sometimes known as a “gather”). These may be indexed loads, as in the example below, or loads with non-unit stride. The compiler has emulated a hardware gather instruction by issuing individual loads for the different memory locations in software.

  • Diagnostic 15423: loop has only one iteration

    Product Version: Intel® Fortran Compiler 15.0 and a later version 

    Cause:

    The Intel® Fortran Compiler will not vectorize a loop when it knows the loop has only one iteration. If the user requires vectorization by using a SIMD directive, the compiler emits a warning diagnostic.
