  • Merging MPI Intercommunicators

    Sometimes you may have completely separate instances for an MPI job.  You can connect these separate instances using techniques such as MPI_Comm_accept/MPI_Comm_connect, which creates an intercommunicator.  But in more complex situations, you may have a significant number of separate intercommunicators, and want to send data between arbitrary ranks, or perform collective operations across all ranks, or other functions which are most efficiently handled over a single intracommunicator.

    Issue Description

    Nmake and ifort are not recognized from a command window, however using Intel Fortran under Visual Studio works perfectly.


    Follow below checklist to troubleshooting Visual Studio command environmental issues:

    1. Verify whether ifort and nmake are installed correctly:

        For Visual Studio 2017, nmake is installed at:

        C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.10.25017\bin\HostX64\x64\nmake.exe

  • Improve encoding efficiency and video quality with Adaptive LTR


    In media application, one important feature of the encoder is to lower the bitrate while keeping the high video quality. Intel® Media SDK has been working hard on improving this capability based on our hardware.

    Media SDK introduces the Adaptive Long Term Reference (LTR) in the 2018R1 Windows release, an intelligent encoding feature which significantly improves compression efficiency and video quality for video conferences, surveillance and certain graphics/game streaming applications.
