The Intel® Cilk™ Plus SDK (Software Development Kit) supplies additional tools for Intel® Cilk™ Plus developers working on the Microsoft Windows* and Linux* operating systems. These tools are especially helpful for users converting from the previous Intel® Cilk++ WhatIf kit to the Intel Cilk Plus implementation provided with the Intel® Parallel Composer 2011 and Intel® C++ Composer XE 2011 products.
The Intel Cilk Plus SDK provides the following tools:
- Intel® Cilk screen race detector (Cilk screen) – Monitors the actual operation of an Intel Cilk Plus program as run with your test input. Cilk screen reports all data races introduced by the Intel Cilk Plus scheduler encountered during execution. By monitoring program execution, Cilk screen can detect races in your production binary, and can even detect races produced by third-party libraries for which you may not have source code.
- Intel® Cilk view scalability analyzer (Cilk view) – Helps you understand the parallel performance of your Intel Cilk Plus program. Cilk view reports parallel statistics about an Intel Cilk Plus program and predicts how the performance will scale on multiple processor systems. In addition, Cilk view can automatically benchmark an Intel Cilk Plus program running on one or more processors.
- Integration of Cilk screen and Cilk view into Microsoft Visual Studio* 2005, 2008 and 2010 on Microsoft Windows* operating systems. Integration into the user’s development environment allows users to view error locations at the click of a mouse.
For more information, see the Intel® Cilk™ Plus SDK User’s Guide.
