Intel® Parallel Composer

OpenMP* 4.0 combined offload constructs support for the Intel® Xeon Phi™ coprocessor

The Intel® Parallel Studio XE 2015 Composer Editions for Windows* and Linux* have feature enhancements that provide near full support of the OpenMP* 4.0 API (July 2013) specification. Extensions to the reduction clause and the new declare reduction construct added to support user defined reductions are not currently supported.

    The Intel® Parallel Studio XE 2015 Composer Editions for Windows* and Linux* have an internal implementation feature enhancement to the Intel® Xeon Phi™ coprocessor binary image created when using the Intel® Language Extensions for Offload (LEO) or OpenMP* 4.0 target constructs.

    The enhancement enables the Intel® 15.0 compilers to create an Executable and Linkable Format (ELF) format executable binary file for Intel® Xeon Phi™ coprocessor offload image. In previous releases, the compiler created an ELF format shared library (.so) binary file.

  • cilk_spawn inside cilk_for

    Hi,

    For some reason, whenever I have a spawn and sync inside a cilk_for it seems as though the spawn does not get recognized.  I end up getting a compile time error of Expected _Cilk_spawn before _Cilk_sync.  As an example consider the following (overly simple) program:

    void foo(){
        cout << "foo";
    }
    
    void bar(){
        cout << "bar";
    }
    
    void baz(){
        cout << "baz";
    }
    
    int main(){
        cilk_for(int i-0; i<10; i++){
            cilk_spawn foo();
            bar();
            cilk_sync;
            baz();
        }
    }

     

    Cilk™ Plus Trademark License for product distribution

    Dear all,

    I need a help to make clear with my customer about Cilk Plus license.

    I have bought a license of Intel Parallel Studio XE 2013 (contains Cilk Plus) to develop a product for my customer.

    Now, my customer want to distribute the product to market.

    Mustn't my customer need to buy a license because I bought it ? can you give for me some evidences to me negotiate with my customer ?

    Thanks,

    Tam Nguyen

    sec_implicit_index

    I've been trying to understand what the implicit_index intrinsic may be intended for.  It's tricky to get adequate performance from it, and apparently not possible in some of the more obvious contexts (unless the goal is only to get a positive vectorization report).

    It seems to be competitive for the usage of setting up an identity matrix.

    In the context of dividing its result by 2, different treatments are required on MIC and host:
