OpenMP 4.0 Fortran -> $omp target map(to:x) Does not copy scalars

Hello. Ever since I tried switching over to openMP 4.0 from LEO my code was not working properly. Finally figured out that during the offload transfer the map clause copies arrays but DOES NOT COPY SCALARS. 

The only way to get scalars copied to the device is to call target update to(scalar)

Can someone please explain this behaviour?

Using icc 15.0.1

EDIT: Scalars created in the same file are copied, but scalars imported from a different file using USE do not get copied. Arrays get copied no matter where they originate from.

  • Internal error in Inspector XE 2016 Beta

    Hi there,

    I have been using the Inspector XE Beta fairly successfully but on my recent run Inspector reported an internal error and ended the analysis. It also states that I should contact the Intel Support team.

    The Inspector reports several data race conditions with 'for__acquire_lun' which I haven't seen before.

    I should say that I am working with Fortran on a linux system. I have also created an Intel Premier support issue where I have uploaded the results dir.

    TBB 4.3 Update 6 does not seem to integrate with Visual Studio 2013

    I just installed the TBB 4.3 Update 6 for Windows and selected integration with Visual Studio 2013 during the installation. Now, in VS 2013 the TBBIncludeDir and TBBLibDir macros are undefined for all configurations in my C++ project property pages.I then re-ran the TBB 4.3 Update 6 installer and selected Modify and it showed the Visual Studio 2013 integration as not being installed.

    Using OpenCL™ 2.0 Read-Write Images

    Acknowledgements

    We want to thank Javier Martinez, Kevin Patel, and Tejas Budukh for their help in reviewing this article and the associated sample.

    Introduction

    Prior to OpenCL™ 2.0, there was no ability to read and write to an image within the same kernel. Images could always be declared as a “CL_MEM_READ_WRITE”, but once the image was passed to the kernel, it had to be either “__read_only” or “__write_only”.

  • Audio routing issue

    Hi Team, I integrated the TLV320AIC3111 codec with intel Z3745 baytrail SOC. Driver is integrated and everything is working fine.

    I have the pfw and xml file for routing, but there is not any alsa_amixer control for the right speaker, left speaker of my board are working but not right.

    even i am changing the value using alsa command only left speaker bits are updated not for the right speaker. I got the files: pfw, xml, and codec driver

    from intel SDK.

    Fast Blur - Native in Android App

    Hi, My name is David Coronel, I'm an android developer from Colombia and currently I'm developing an app which uses real time blur combined with a slide up panel so the blur can get above of an image and make it blurried behind, I've been able to accomplish this task by creating a RelativeLayout whit some render script, but it is higly memory-demandant and after some time using the app it gets laggy and finally gets killed by the OS becouse ended up with a very high memory heap

    Searching on the web for other methods to do fast blur I've found this great blog post

    Hardware H.264 encoder encoding failed

    Hi

    I'm trying to use Intel hardware H.264 encoder MFT (Window Media Foundation) on my machine which has an Intel Core i5-2400 CPU and latest Intel driver installed. 

    The code I tested is based on the example here https://msdn.microsoft.com/en-us/library/windows/desktop/ff819477%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396
