international symposium on parallel and distributed Processing (IPDPS)

We present some preliminary results of selective profiling in our efforts towards automatic performance tuning for scientific codes. Performance analysis and tuning are becoming very important with the increasing complexity and speed of high performance systems. Great efforts are necessary to tune applications for optimal performance on such systems. In our efforts to automate most, if not all, of the performance tuning process, we developed a flexible profiling tool that can quickly pinpoint the performance bottlenecks and further refine the problem area. This is an important first step in our open framework with a rule-based approach for our ongoing PERCS project.

Reconfigurable devices, such as field programmable gate arrays (FPGAs), are very popular in today's embedded systems design due to their low-cost, high-performance and flexibility. Partially runtime-reconfigurable (PRTR) FPGAs allow hardware tasks to be placed and removed dynamically at runtime. Hardware task scheduling on PRTR FPGAs brings many challenging issues to traditional real-time scheduling theory, which have not been adequately addressed by the research community compared to software task scheduling on CPUs. In this paper, we consider the schedulability analysis problem of HW task scheduling on PRPR FPGAs. We derive utilization bound tests for two variants of global EDF scheduling, and use synthetic tasksets to compare performance of the tests to existing work and simulation results.

Client-Side Implementation of Dynamic Asynchronous Invocations for Web Services

international symposium on parallel and distributed Processing (IPDPS)

作者： Giancarlo Tretola Dept. of Engineering University of Sannio Benevento Italy

Web Services are becoming more and more fundamental building blocks of Web-based distributed applications and a core technology for grid systems. Due to their flexibility, Web Services easily combine, in a common and coherent framework, ubiquitous computing with heterogeneous applications composed of different kinds of resources and, typically distributed in many organizations. We expect that this technology will follow the same evolution paths that have characterized other technologies so far, with some specificity due to the openness and size of the application context. In this connection, optimizations tied to invocations and workflows are assuming a primary role in Web Services research. The synchronous request/reply nature of the most diffused underling protocol (HTTP) introduces several restrictions in many application scenarios. On the other hand, asynchronous interactions are allowed by using message oriented middleware platforms, like JMS, which are typically harder to handle than object- and process-oriented middleware. In this paper, we propose a first implementation of a module that allows for dynamic Web Services invocations, which, on the basis of metadata added to WSDL, is able to select the most appropriate invocation technique for calling a Web Services operation.

international symposium on parallel and distributed Processing (IPDPS)

作者： Srinivas Vadlamani Stephen Jenks Department of Electrical Engineering and Computer Science University of California Irvine CA USA

Chip multiprocessors (CMPs) and simultaneous multithreading (SMT) processors provide high performance but put more pressure on the memory interface than their single-thread counterparts. The "memory wall" problem is exacerbated by multiple threads sharing a memory interface, and will get worse as more cores are added. Therefore, communications between cores, using shared caches or fast interconnects between private caches, are needed to keep the CPUs busy without burdening the memory interface. Multiple CMP systems add another dimension to this challenging problem, as the communication mechanism is no longer uniform. To parallelize data-intensive applications for high performance on these systems, one must explore a number of execution behaviors in a complex architecture-dependent exercise that entails identifying key components of the communication subsystem and understanding their behavior under varying workloads. As part of ongoing research into efficient program execution models for parallel microprocessors, we have developed a tool to evaluate the performance of the storage controllers at different levels of the memory hierarchy under varying workloads and measure cache coherence overhead. The tool allows exploration of architectural features of real processors that affect the performance of several parallel execution approaches. Here, we demonstrate its use by evaluating two of our parallel programming models that employ architecture-specific optimizations and compare them to a conventional model for several applications on parallel microprocessors.

Reprogramming is an essential service for wireless sensor networks. Authenticating reprogramming process is important as sensors need to verify that the code image is truly from a trusted source. There are two ways to achieve authentication: public key based and symmetric key based. Although previous work has shown that public key authentication is feasible on sensor nodes if used sparingly, it is still quite expensive compared to symmetric key based approach. In this paper, we propose a symmetric key based protocol for authenticating reprogramming process. Our protocol is based on the secret instantiation algorithm from, which requires only O(log n) keys to be maintained at each sensor. We integrate this algorithm with the existing reprogramming protocol. Through simulation, we show that it is able to authenticate reprogramming process at very low communication cost, and has very short delay.

Many large-scale production applications often have very long executions times and require periodic data checkpoints in order to save the state of the computation for program restart and/or tracing application progress. These write-only operations often dominate the overall application runtime, which makes them a good optimization target. Existing approaches for write-behind data buffering at the MPI I/O level have been proposed, but challenges still exist for addressing system-level I/O issues. We propose a two-stage write-behind buffering scheme for handing checkpoint operations. The first-stage of buffering accumulates write data for better network utilization and the second-stage of buffering enables the alignment for the write requests to the file stripe boundaries. Aligned I/O requests avoid file lock contention that can seriously degrade I/O performance. We present our performance evaluation using BTIO benchmarks on both GPFS and Lustre file systems. With the two-stage buffering, the performance of BTIO through MPI independent I/O is significantly improved and even surpasses that of collective I/O.

On the Role of Deterministic Fine-Grain Data Synchronization for Scientific Applications: A Revisit in the Emerging Many-Core Era

作者： Weirong Zhu Ziang Hu Guang R. Gao Department of Electrical & Computer Engineering University of Delaware Newark DE USA

The design of microprocessor chip for high-end computing systems is moving towards many-core architectures with 10s or 100+ processing units. An important class of the target applications for such architectures are scientific numerical computations, many of which are intrinsically deterministic - that is for a given input a fixed output (result) should be produced no matter how the program is parallelized. It is critical that the read-after-write data dependencies in such programs should be implemented correctly and efficiently via fine-grain data synchronization. In this paper, we investigate the parallelization of three representative scientific computation kernels using fine-grain data synchronization supported by an recently proposed architectural mechanism for many-core chips, called synchronization state buffer (SSB). Using detailed simulation on a simulator for the IBM 160-core Cyclops-64 chip architecture with the SSB extension, our experiments demonstrate significant performance advantage of using fine-grain data synchronization based parallelization schemes for scientific workloads.

Module Composition within Petri Nets Model-based Development

Module Composition within Petri Nets Model-based Development

international symposium on Industrial Embedded systems

作者： Aniko Costa Luis Gomes Faculdade de Ciencias e Tecnologia & UNINOVA Universidade Nova de Lisboa Caparica Portugal

Model based development within the area of hardware-software embedded systems co-design has been used as a major attitude to support embedded system complexity increasing during the last decade. Several modeling formalisms are very well matched for usage within this area. One of the main goals of the work presented in this paper is to contribute for the usage of Petri nets as the system-level specification language within model-based development of embedded systems using co-design techniques. System model partitioning into modules and components ready to be implemented in hardware or software and be deployed into a distributed platform is a major concern within co-design methodologies. A net operation, called net splitting, is used in this paper in order to decompose a Petri net model into several Petri net submodels, which will be executed in parallel using synchronous communication channels. Those Petri net sub-models are seen as modules or components ready to be used for distributed execution of the initial model. In this paper, we propose a set of techniques to allow module replication and their composition in new situations, supporting module reutilization, which has a key impact factor within engineering activities. The proposed techniques rely on keeping the module interface unchanged in order to support the integration of the module in new situations.

Scientific simulations modeling complex physical phenomena exhibit varying degrees of spatiotemporal and computational heterogeneity, which can pose significant challenges in algorithmic efficiency and runtime performance. Addressing these challenges often requires an understanding of application behavior and the impact of heterogeneity on the simulation, especially when analytical approaches are not feasible. Runtime calibration is used to analyze the impact of computational heterogeneity on the performance of two different load balancing strategies applied to two different problems of 2-D methane-air combustion using different chemistry models. Experimental evaluation demonstrates that such empirical approaches are inevitable in component-based scientific computations, where performance is determined by the problem characteristics and the particular connectivity of components in the simulation code, none of which are known before runtime.

The design of a general-purpose dynamic load balancing library for a vast variety of parallel applications is a very challenging task. The library has to address potentially unpredictable load imbalance in the application, to interface with the data structures native to the application and to achieve significant performance improvement and scalability. In this paper we look into the design and sample results of a new dynamic load balancing library called LB Migrate, targeted for large scientific applications with parallel loops as a major source of concurrency. The applicatons must supply the library a routine that encapsulates the computations for a chunk of loop iterates, and the data for the computations must be stored in an array of arbitary type. We demonstrate the effectiveness of the library on two real applications - the profiling of an automatic quadrature routine problem and for a simulation of a hybrid model for image denoising. The experimental results indicate that the library achieves up to 60 % performance improvement for these applications.
