The main idea behind UPC is that users should be able to view the underlying machine model as a collection of threads operating in a common global address [5]. In such an environment fine-grain algorithms are preferred to coarse-grain algorithms since they are easier to code. While such algorithms, written in UPC, should have similar performance in shared memory environments compared to OpenMP,...

This paper addresses issues of task clustering-the coalition of several fine grain tasks into single coarser grain tasks called task clusters+md task cluster scheduling on distributed processors. The performance of various scheduling schemes is studied and compared f o r a variety of workloads. Simulation results indicate that the scheduling policy that gives priority to the cluster with the ,s...

We discuss high-performance programmable asynchronous pipeline arrays (PAPAs). These pipeline arrays are coarse-grain field programmable gate arrays (FPGAs) that realize high data throughput with fine-grain pipelined asynchronous circuits. We show how the PAPA architecture maintains most of the speed and energy benefits of a custom asynchronous design, while also providing post-fabrication logi...

Desirable grain quality attributes vary depending upon the intended end use of grain. Environment, production practices and genetics are all of importance. Nutritional value of grain is most important for animal feed. Dry mill and alkaline cooked products require hard kernels with low breakage susceptibility and high protein concentration. Grain for these uses would best be produced under dryla...

a r t i c l e i n f o It is well known that strong concurrent precipitation, mainly located along grain/subgrain boundaries, results in a coarse and elongated grain structure, and unusual sharp P {011} b566N and/or M {113} b110N texture components during annealing of supersaturated AA3xxx-series alloys. In this study, a supersaturated as-cast Al–Mn– Fe–Si alloy was annealed at three temperature...

Median grain sizes on riverbeds range from boulders in uplands to silt in lowlands; however, rivers with ~1–5mm diameter bed sediment are rare. This grain size gap also marks an abrupt transition between graveland sand-bedded reaches that is unlike any other part of the fluvial network. Abrupt gravel-sand transitions have been attributed to rapid breakdown or rapid transport of fine gravel, or ...

In developing country like India due to the remarkable development in road infrastructure, Soil stabilization has become the major issue in construction activity. Stabilization is an unavoidable for the purpose of highway and runway construction, stabilization denotes improvement in both strength and durability which are related to performance. Stabilization is a method of processing available ...

Providing efficient support for interactive operations such as fast-forward and fast-backward is essential in video-on-demand and other multimedia server systems. In this paper, we present two basic approaches for scheduling interactive operations, the prefetching approach and the grouping approach. Scheduling algorithms are presented for both fine-grain and coarse-grain data blocks. These algo...

Software-implementations of shared memory are still far behind the performance of hardware-based shared memory implementations (HW-DSM) and are not viable options for most fine-grain shared memory applications. The major source for their inefficiency comes from the cost of interrupt-based asynchronous protocol processing, not from the actual network latency. As the raw hardware latency of inter...

This paper examines simultaneous multithreading, a technique permitting several independent threads to issue instructions to a superscalar's multiple functional units in a single cycle. We present several models of simultaneous multithreading and compare them with altemative organizations: a wide superscalar, a fine-grain multithreaded processor, and single-chip, multiple-issue multiprocessing ...
