Optimizing the Performance of Streaming Numerical Kernels on the IBM Blue Gene/P PowerPC 450 Processor

Abstract: Several emerging petascale architectures use energy-efficient processors with vectorized computational units and in-order thread processing. On these architectures the sustained performance of streaming numerical kernels, ubiquitous in the solution of partial differential equations, represents a challenge despite the regularity of memory access. Sophisticated optimization techniques are required to fully utilize the Central Processing Unit (CPU). We propose a new method for constructing streaming numerical kernels using a high-level assembly synthesis and optimization framework. We describe an implementation of this method in Python targeting the IBM Blue Gene/P supercomputer's PowerPC 450 core. This paper details the high-level design, construction, simulation, verification, and analysis of these kernels utilizing a subset of the CPU's instruction set. We demonstrate the effectiveness of our approach by implementing several three-dimensional stencil kernels over a variety of cached memory scenarios and analyzing the mechanically scheduled variants, including a 27-point stencil achieving a 1.7x speedup over the best previously published results.

Making RISC respectable-the Motorola 88000

Abstract: The reduced instruction set computer (RISC) was initially regarded with considerable scepticism, but Motorola's launch of a new RISC processor represents a significant advance in the acceptance of the RISC design philosophy

Achieving digital controller with open architecture addressing capability and obsolescence for marine power plant

Abstract: The traditional marine gas turbine control system usually used hydraulic and electrical control, which could achieve the three main functions of monitoring, control and protection. With the control requirements of the marine gas turbine continuously improved, the use of distributed digital control system was an important development direction. The digital controller was a core part of distributed digital control system. Currently, there was a plethora of low-cost commercial off-the-shelf hardware available for implementing digital controller, such as PowerPC, PLCs and PC-based boards, SoC, ASICS and so on. When considering the construction of complex distributed systems for marine power plant, the ability to rapidly integrate a variety of devices from different manufacturers is essential. In this paper, based on an open architecture, a digital controller was designed in order to verify the gas turbine distributed control system. The gas turbine distributed digital control LAN semi-physical simulation platform which includes multi-smart devices has been established and a distributed system demonstrator that has been developed to explore future distributed control systems.
