英特尔® Cilk™ Plus

Run-time exit function

Hello,
I would like to understand run-time execution in Cilk a little better. 
I have downloaded Intel Cilk run-time release (cilkplus-rtl-003365 - released 3-May-2013).

On 09/09/2013 I had asked a question seeking to figure out which is the last function executed before Cilk run-time ends assuming execution went without any problems.

Barry suggested to look at “__cilkrts_c_return_from_initial()” in scheduler.c  and indeed that was what I needed at that time.

Cilk worker

Hello,

I would like to understand Cilk worker creation a litter better.
I am not sure how to phrase this question so I’ll give it my best.
I have downloaded Intel Cilk runtime release (cilkplus-rtl-003365 -  released 3-May-2013).

I would like to create a new Cilk worker that does not cause cross-threading issues but this new worker would not be a part of the work collective.

全新 Android* 世界的可信赖工具:优化技术 — 从英特尔® SSE 内部指令到英特尔® Cilk™ Plus

作者: 英特尔高级软件应用工程师 Zvi Danovich

简介

大部分的 Android 应用 — 即使是仅基于脚本和管理语言 (Java*, HTML5,…) 的应用 — 最终都会使用中间件功能,因为该功能能够利用优化特性。

本文将介绍基于 Android 的优化需求和方法,并详述一个优化多媒体和增强现实应用的案例。

英特尔为 Android 平台(智能手机和平板电脑)提供了多种不同的英特尔® 凌动™ 处理器,至少包括英特尔® SIMD 流指令扩展补充版(英特尔® SSSE3)级别的矢量功能,通常包括两个内核和超线程。

理解并使用这些优化功能吧!

  • 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();
        }
    }
