When performing source-to-source compilation of Co-array Fortran (CAF) programs into SPMD Fortran 90 codes for shared-memory multiprocessors, there are several ways of representing and manipulating data at the Fortran 90 language level. We describe a set of implementation alternatives and evaluate their performance implications for CAF variants of the STREAM, Random Access, Spark98 and NAS MG &...

نخستین گام در راستای تحلیل و ارزیابی ریسک‌های زنجیره تأمین شناسایی این ریسک‌ها است. روش‌های مرسوم بر اساس فیلترهای دستی یا خودکار داده‌­محور ارائه شده فیلتر به‌­دلیل محدودیت‌های نمونه‌گیری دارای مشکلات اعتبارسنجی هستند از طرف دیگر مبتنی داده، داده‌های ریسک که پیچیده مبهم هستند، عملکرد ضعیفی دارند. برای پرکرده خلل پژوهشی، پژوهش، چارچوبی تعاملی بین تحلیل‌­گر ماشین حجم وسیعی حوزه مواد غذایی با است...

Issues affecting the performance of dataflow computers at the machine and language levels are explored. It is suggested that performance is dictated by the nature and the means of identification, distribution and control of workload in the hardware system. Dataflow is an asynchronous concurrent notation based on fine-grain message-passing in graphical programs. Dataflow machines comprise multip...

We describe a programming abstraction for heterogeneous parallel hardware, designed to capture a wide range of popular parallel hardware, including GPUs, vector instruction sets and multicore CPUs. Our abstraction, which we call HPVM , is a hierarchical dataflow graph with shared memory and vector instructions. We use HPVM to define both a virtual instruction set (ISA) and also a compiler inter...

This paper describes a turnkey solution to add a XML digital signature capability withoutmodifying existing XML-based B2B systems. The signature proxy between applicationswatches for XML messages exchanged on the network. Outboundmessages are received by the proxy and automatically signed and by a signature server implemented as a Web service. Inbound messages are also verified by using the pro...

We consider how to distribute sparse matrices among processes to reduce communication costs in parallel sparse matrix computations, specifically, sparse matrix-vector multiplication. Our main contributions are: (i) an exact graph model for communication with general (two-dimensional) matrix distribution, and (ii) a recursive partitioning algorithm based on nested dissection (substructuring). We...

We present a class of efficient models called MobileNets for mobile and embedded vision applications. MobileNets are based on a streamlined architecture that uses depthwise separable convolutions to build light weight deep neural networks. We introduce two simple global hyperparameters that efficiently trade off between latency and accuracy. These hyper-parameters allow the model builder to cho...

ARMI is a communication library that provides a framework for expressing finegrain parallelism and mapping it to a particular machine using shared-memory and message passing library calls. The library is an advanced implementation of the RMI protocol and handles low-level details such as scheduling incoming communication and aggregating outgoing communication to coarsen parallelism. These detai...

Discussions concerning transsexual identities consider the self representations of transsexuals as either determined through medical discourses and practices, and thus as constructed and inauthentic or, alternatively, as expressive of an interior and thus ‘authentic’ essential self. In contrast to each of these arguments, this paper highlights the significance of social interaction to transsexu...
