Integration issues with Visual Studio 2015 Update 1

I just installed evaluation version of Intel® Parallel Studio XE 2016 Cluster Edition for Windows with Update 1 on Windows 7 SP 1 64-bit. I used defaults during installation, except of unchecking the Fortran compiler and 32-bit tools. Prior to installation I already had a working Visual Studio 2015 Community Edition with Update 1. I don't see any trace of Intel C++ compiler in Visual Studio, not in PROJECT menu, nor anywhere else. Intel Software Manager app, which was installed with Parallel Studio XE, crashes with Missing Shortcut error. Command line tools seem to be working.

  • Errors when compile RInside using intel c++ compiler on windows

    I have read the mailing list about compiling Rusing intel c++ compiler on linux.
    http://lists.r-forge.r-project.org/pipermail/rcpp-devel/2013-January/005...

    In my environment I am going to compile RInside using intel c++ compiler on windows.
    I take the sample0 in RInside example folder for test. It's the "Hello world" example.
    After fixing all the compile errors following lingk errors appears:

    C++11 class member initialization for strings

    Hello,

    I am having an issue, I really can't find an answer to. With the following code, I get a segmentation fault. But only for -O2 / -O3. -O0 and -O1 are fine.

    The fault does occur with the C++11 initialization of the string member additionalMessage = ""; If this is not pre-set, it works just fine.

    When I replace the member with char*, the code works as expected.

    Linker error using c++ Compiler 16 for windows

    I am upgrading the c++ compiler from version 15 to 16 (on windows 7) using visual studio 2010 IDE

    The compilation passes ok but i get many linker error on the same issue

    Following are a couple of errors from the long list of similar errors :

    Error    290    error LNK2005: "class F64vec8 __cdecl andnot(class F64vec8 const &,class F64vec8 const &)" (?andnot@@YA?AVF64vec8@@AEBV1@0@Z) already defined in sys.lib(c_run_graph.obj)    D:\VsProjects\VS4-Ver1.8x64\src\evpcon\svp.lib(cRawDataFilterSliceMgr.obj)

    Why does compiler generate VGATHER instructions?

    Working with the Intel compiler (icc (ICC) 15.0.3 20150407), I have a simple loop for which the compiler is generating what looks like terrible code.

    The loop is a trivial calculation over a contiguous range of indices of some float arrays:

        for (i=Nwin+Ngap; i<N-Nwin-Ngap; i++) {
            w_avg[i] = avgscale2*(slidingsum[i+Ngap+1]+slidingsum[i-Ngap-Nwin]);
        }
    

    The assembler output shows a completely reasonable piece of scalar code for the short vector case:

    Consistency with long double

    Hi,

    I am working on a C++ program which is heavy on number crunching. After an update of the program that has nothing to do with floating points (I have added non floating point members to some classes), I realized that there was a slight change in the floating point results of the program. The difference is very small (a small drift starting from 1ulp), but it is there.

    I've tracked the difference in between the 2 versions of the program, until I found the culprit : a routine that was using the type "long double". When changed to "double", the difference went away.
