The IBM Software Development Kit (SDK) for Multicore Acceleration

Reliable and easy modification IBM SDK for Multicore Acceleration Systems based on multi-core is a highly reliable and easy-to-use microprocessors offer outstanding development tool kit with IBM warranty processing performance over and support. It provides debugging conventional processors. Those tools, performance tuning tools and an companies willing to modify their integrated development environment, applications to take full advantage all of which run on enterprise-level of the Cell Broadband Engine (Cell/ ®. Using this SDK, you can plug B.E.) architecture can benefit from in third party ISV libraries, helping your these high performance processors software ecosystem to integrate to leap ahead of their competitors. To and grow. help you optimize your applications quickly using your existing software The IBM SDK for Multicore development staff, IBM has developed Acceleration includes the following components: Highlights a software development kit that accelerates multi-core programming. • -based integrated ■ Port and optimize applications development environment (IDE) and algorithms for the Cell IBM® Software Development Kit • Development libraries and Broadband Engine™ quickly, (SDK) for Multicore Acceleration V3.0 frameworks using your existing software contains the essential tools required • GNU toolchain development staff for developing programs for Cell/B.E. • Sysroot Image for System Simulator ■ Establish a highly reliable and -based server—the IBM BladeCenter® • Performance tools easy-to-use development tool kit QS21—with libraries, frameworks • Example codes and tutorials for the Cell Broadband Engine and application development tools. It uses Synergistic Processing Elements ■ Extend and optimize developer (SPEs) for offloading numerically productivity intensive computing functions from ■ Facilitate programming for multi- more general purpose x86 and IBM core and multi-processor POWER™-based processors. architectures The IBM Software Development Kit (SDK) for Multicore Acceleration

Eclipse-based IDE The Eclipse-based IDE is an tool for building, compiling and debugging applications using the compilers, programming model frameworks and analysis tools of the SDK.

Development libraries and frameworks The Accelerated Library Framework (ALF) provides a programming environment for data and task parallel applications and libraries. The ALF API provides library developers with Figure 1: A graphical view of the IBM SDK software stack. a set of interfaces to simplify library BLAS (Basic Linear Algebra GNU toolchain development in heterogeneous multi- Subroutines) is an API for commonly The GNU toolchain provides core core systems. Library developers can used linear algebra operations in high- functionality for program execution use our provided framework to offload performance computing (HPC) and (in overlays and library support), the computationally intensive work other scientific domains. It is widely debugging, GNU C/C++ compiler to the accelerators. More complex used as the basis for other high-quality functionality and performance applications can be developed by linear algebra software. enhancements. IBM has also combining the several-function developed this SDK with increased offload libraries. Standardized SIMD math libraries programming language support are provided for the PPE Vector and for SPEs. The Data Communication and SIMD Multimedia Extension and the Synchronization (DaCS) library SPE. By computing multiple results at Sysroot Image for System Simulator provides a set of services that facilitate one time, SIMD math functions help Sysroot Image for System Simulator the development of applications programmers obtain much higher provides libraries and binaries that can and application frameworks in a performance from their PPE and SPE be used in the system simulator. It is heterogeneous multi-tiered system programs than would be possible from pre-loaded with a full range of utilities, (for example, memory hierarchy). The a corresponding traditional scalar including all of the Cell/B.E. Linux DaCS services are implemented as math library. support libraries. a set of APIs that provide a layer of architecture neutrality for application developers in a variety of multi-core memory hierarchy systems.
