2012	PAMI: A Parallel Active Message Interface for the Blue Gene/Q Supercomputer abstract The Blue Gene/Q machine is the next generation in the line of IBM massively parallel supercomputers, designed to scale to 262144 nodes and sixteen million threads. With each BG/Q node having 68 hardware threads, hybrid programming paradigms, which use message passing among nodes and multi-threading within nodes, are ideal and will enable applications to achieve high throughput on BG/Q. With such unprecedented massive parallelism and scale, this paper is a groundbreaking effort to explore the design challenges for designing a communication library that can match and exploit such massive parallelism In particular, we present the Parallel Active Messaging Interface (PAMI) library as our BG/Q library solution to the many challenges that come with a machine at such scale. PAMI provides (1) novel techniques to partition the application communication overhead into many contexts that can be accelerated by communication threads, (2) client and context objects to support multiple and different programming paradigms, (3) lockless algorithms to speed up MPI message rate, and (4) novel techniques leveraging the new BG/Q architectural features such as the scalable atomic primitives implemented in the L2 cache, the highly parallel hardware messaging unit that supports both point-to-point and collective operations, and the collective hardware acceleration for operations such as broadcast, reduce, and all reduce. We experimented with PAMI on 2048 BG/Q nodes and the results show high messaging rates as well as low latencies and high throughputs for collective communication operations.

2012	Looking under the hood of the IBM blue gene/Q network abstract This paper explores the performance and optimization of the IBM Blue Gene/Q (BG/Q) five dimensional torus network on up to 16K nodes. The BG/Q hardware supports multiple dynamic routing algorithms and different traffic patterns may require different algorithms to achieve best performance. Between 85% to 95% of peak network performance is achieved for all-to-all traffic, while over 85% of peak is obtained for challenging bisection pairings. A new software-controlled algorithm is developed for bisection traffic that selects which hardware algorithm to employ and achieves better performance than any individual hardware algorithm. The benefit of dynamic routing is shown for a highly non-uniform "transpose" traffic pattern. To evaluate memory and network performance, the HPCC Random Access benchmark was tuned for BG/Q and achieved 858 Giga Updates per Second (GUPS) on 16K nodes. To further accelerate message processing, the message libraries on BG/Q enable the offloading of messaging overhead onto dedicated communication threads. Several applications, including Algebraic Multigrid (AMG), exhibit from 3 to 20% gain using communication threads. Dong Chen 0005, Noel Eisley, Philip Heidelberger, Sameer Kumar 0001, Amith R.

2011	The IBM Blue Gene/Q interconnection network and message unit abstract This is the first paper describing the IBM Blue Gene/Q interconnection network and message unit. The Blue Gene/Q system is the third generation in the IBM Blue Gene line of massively parallel supercomputers. The Blue Gene/Q architecture can be scaled to 20 PF/s and beyond. The network and the highly parallel message unit, which provides the functionality of a network interface, are integrated onto the same chip as the processors and cache memory, and consume 8% of the chip's area. For better application scalability and performance, we describe new routing algorithms and new techniques to parallelize the injection and reception of packets in the network interface. Measured hardware performance results are also presented. Dong Chen 0005, Noel Eisley, Philip Heidelberger, Robert M. Senger, Yutaka Sugawara, Sameer Kumar 0001, Valentina Salapura, David L.

2005	Optimization of MPI collective communication on BlueGene/L systems abstract BlueGene/L is currently the world's fastest supercomputer. It consists of a large number of low power dual-processor compute nodes interconnected by high speed torus and collective networks, Because compute nodes do not have shared memory, MPI is the the natural programming model for this machine. The BlueGene/L MPI library is a port of MPICH2.In this paper we discuss the implementation of MPI collectives on BlueGene/L. The MPICH2 implementation of MPI collectives is based on point-to-point communication primitives. This turns out to be suboptimal for a number of reasons. Machine-optimized MPI collectives are necessary to harness the performance of BlueGene/L. We discuss these optimized MPI collectives, describing the algorithms and presenting performance results measured with targeted micro-benchmarks on real BlueGene/L hardware with up to 4096 compute nodes.

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. George S. Almási, Daniel K.

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. Narasimha R.
