2002 Blue Gene/L, a System-On-A-Chip
abstract
Summary form only given. Large powerful networks coupled to state-of-the-art processors have traditionally dominated supercomputing. As technology advances, this approach is likely to be challenged by a more cost-effective System-On-A-Chip approach, with higher levels of system integration. The scalability of applications to architectures with tens to hundreds of thousands of processors is critical to the success of this approach. Significant progress has been made in mapping numerous compute-intensive applications, many of them grand challenges, to parallel architectures. Applications hoping to efficiently execute on future supercomputers of any architecture must be coded in a manner consistent with an enormous degree of parallelism. The BG/L program is developing a peak nominal 180 TFLOPS (360 TFLOPS for some applications) supercomputer to serve a broad range of science applications. BG/L generalizes QCDOC, the first System-On-A-Chip supercomputer that is expected in 2003. BG/L consists of 65,536 nodes, and contains five integrated networks: a 3D torus, a combining tree, a Gb Ethernet network, barrier/global interrupt network and JTAG.

2002 An overview of the BlueGene/L Supercomputer
abstract
This paper gives an overview of the BlueGene/L Supercomputer. This is a jointly funded research partnership between IBM and the Lawrence Livermore National Laboratory as part of the United States Department of Energy ASCI Advanced Architecture Research Program. Application performance and scaling studies have recently been initiated with partners at a number of academic and government institutions,including the San Diego Supercomputer Center and the California Institute of Technology. This massively parallel system of 65,536 nodes is based on a new architecture that exploits system-on-a-chip technology to deliver target peak processing power of 360 teraFLOPS (trillion floating-point operations per second). The machine is scheduled to be operational in the 2004-2005 time frame, at price/performance and power consumption/performance targets unobtainable with conventional architectures.

2001 Demonstrating the scalability of a molecular dynamics application on a Petaflop computer
abstract
The IBM Blue Gene project has endeavored into the development of a cellular architecture computer with millions of concurrent threads of execution. One of the major challenges of this project is demonstrating that applications can successfully exploit this massive amount of parallelism. Starting from the sequential version of a well known molecular dynamics code, we developed a new application that exploits the multiple levels of parallelism in the Blue Gene cellular architecture. We perform both analytical and simulation studies of the behavior of this application when executed on a very large number of threads. As a result, we demonstrate that this class of applications can execute efficiently on a large cellular machine.

2000 Transformational Placement and Synthesis
abstract
Novel methodology and algorithms to seamlessly integrate logic synthesis and physical placement through a transformational approach are presented. Contrary to most placement algorithms that minimize a global cost function based on an abstract representation of the design, we decomposed the placement function into a set of transforms and coupled them directly with incremental timing, noise, and/or power analyzers. This coupling results in a direct and more accurate feedback on optimizations for placement actions. These placement transforms are then integrated with traditional logic synthesis transforms leading to a converging set of optimizations based on the concurrent manipulation of boolean, electrical, as well as physical data. Experimental results indicate that the proposed approach creates an efficient converging design flow that eliminates placement and synthesis iteration. It results in timing improvements, and maintains other global placement measures such as wire congestion and wire length. The flexibility of the transformational approach allows us to easily add, extend and support more sophisticated algorithms that involve critical as well as non-critical regions and target a variety of metrics including noise, yield and manufacturability:.

1999 Performance Driven Optimization of Network Length in Physical Placement
abstract
A novel technique to significantly improve the performance of a design by the movement of sets of gates during or after timing driven placement is proposed. A method to identify optimal set of circuit (gate) movements to enhance timing is presented. Experimental results with a min-cut placement tool indicate that the proposed approach of direct manipulation of circuit locations, significantly improves the timing of large partitions of a chip.

1990 Timing Driven Placement Using Complete Path Delays
abstract
The Timing Drive Placement (TDP) system balances wirability and timing constraints so that the final released design meets timing criteria. This is achieved by dynamically evaluating the timing of critical paths during placement. TDP is significant because convergence to a timed wirable solution early in the physical design cycle is achieved, or else it becomes apparent that logic changes are required.

1978 9-V Algorithm for Test Pattern Generation of Combinational Digital Circuits
abstract
An algorithm for generating test patterns for combinational circuits has been developed and programmed. The algorithm is definitive and finds a test for all faults including those that require multiple paths to be sensitized, by sensitizing a single path at a time and trying at most each single path. This is achieved by using a new calculus based on nine values (0,1,D,D̄,0/D,0/D̄, 1/D,1/D̄,U). One path is deliberately sensitized while the alternative paths are assigned values which permit the option of desensitizing or sensitizing them as the sensitized path is developed. Experimental results are presented for a variety of cases.
