    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.

    Long license checkout on remote workstations

    Problem:

    License checkout for 2106 and newer product versions is very slow compared to the 2015 version on machines with remote access to the floating license server.

    Environment:

    Windows*

  • Microsoft Windows* (XP, Vista, 7)
  • Microsoft Windows* 10
  • Microsoft Windows* 8.x
  • C/C++
  • Fortran
  • Intel® Parallel Studio XE Composer Edition
  • Intel® C++ Compiler
  • Intel® Fortran Compiler
  • Intel® License Manager for FLEXlm*
  • licensing
  • checkout
  • Floating License
  • Development Tools
  • Long license checkout on Linux with ipv6

    Problem:

    There is a delay of ~25 seconds when a floating license is checked out.

    Environment:

    Linux* RHEL/CentOS* v7.2

    Root Cause:

    There is a bug in Red Hat 7.2 which adds a 25 second timeout to a library call used to checkout a floating license when IPv6 is disabled.  Bug is described here.

  • Новые возможности Intel® RealSense™ SDK 2016 R2

    Второй выпуск Intel® RealSense™ SDK (для Windows) в 2016 году (2016R2) — версия 10.0.26.0396.
    Наименьшие версии DCM для камер Intel® RealSense™ увеличены: 2.1.24.9476 для камеры R200, 3.1.25.1077 для камеры SR300. Для камеры F200 требуется версия 1.4.27.41944 или более поздняя. Поддерживаемая версия Unity увеличена до 5.2.3.p3 или более поздней (ранее поддерживалась версия 4.1). Примечание. Для Unity 5 требуются 64-разрядные библиотеки.

    Intel® MPI Library 2017 Known Issue: MPI_Bcast Hang on Large User-Defined Datatypes

    Symptom:

    On certain platforms (KNL and BDW), using MPI_Bcast on a user-defined datatype larger than 16 KB will cause the Intel® MPI Library 2017 to hang.  This has been seen in Qbox and miniDFT in Quantum Espresso, as well as in the Intel® Math Kernel Library ?gebr2d class of subroutines.

    Workaround:

    Changing the default algorithm for large messages for the impacted platforms will avoid the hang.  Set the following environment variable:

  • Linux*
  • Microsoft Windows* (XP, Vista, 7)
  • Microsoft Windows* 10
  • Microsoft Windows* 8.x
  • C/C++
  • Fortran
  • Intel® MPI Library
  • Message Passing Interface (MPI)
  • Cluster Computing
  • ipo: warning #11021: unresolved symbols referenced a dynamic library
