An introduction to compiling for the Cell Broadband Engine architecture, Part 4: Partitioning large tasks

Divide and conquer: Parallelizing partitioned jobs

Power Architecture editors, developerWorks, IBM

The developerWorks Power Architecture editors welcome your comments on this article. E-mail them at dwpower@us.ibm.com.

Summary: This tutorial, fourth and penultimate in the "An introduction to compiling for the Cell Broadband Engine™ architecture" series, discusses ways to partition code to run across the multiple cores available in a Cell Broadband Engine™ (Cell BE) processor. It gives particular attention to efficient partitioning of code to allow larger programs or data sets to be manipulated using the 256KB of local store available on the Synergistic Processor Elements (SPEs).
