The rounding of orders to achieve a batch size is recognised as a source of the bullwhip problem within supply chains. While it is often advocated that batch sizes should be reduced as much as possible, there has been limited investigation into the impact of batching on bullwhip. Here we consider scenarios where orders are placed only in multiples of a fixed batch size, for both deterministic a...

Both software-initiated and hardware-initiated prefetching have been used to accelerate shared-memory server performance. While software-initiated prefetching require instruction set and compiler support, hardware prefetching often require additional hardware structures or extra memory state. The coherence batching scheme proposed in this paper keeps the system completely binary transparent and...

In this paper, we propose and evaluate the performance of a multicast technique, called controlled CIWP, for supplying video-on-demand services. Similar to batching schemes, controlled CIWP allows two clients that request the same video to share a channel. Unlike batching, the controlled CIWP scheme does not delay the earlier request in order to promote sharing. Instead, sharing is ensured by p...

In this note we consider a new problem, the so-called bin-batching problem related to variablesized bin covering. A best possible on-line algorithm is presented. ? 2001 Elsevier Science B.V. All rights reserved.

We introduce a homomorphic batching technique that can be used to pack multiple ciphertext messages into one ciphertext for parallel processing. One is able to use the method to batch or unbatch messages homomorphically to further improve the flexibility of encrypted domain evaluations. In particular, we show various approaches to implement Number Theoretic Transform (NTT) homomorphically in FF...

Current streaming languages place significant restrictions on the structure of parallelism that they support, and usually do not allow for dynamic task parallelism. In contrast, there are a number of task-parallel programming models that support dynamic parallelism but lack the ability to set up efficient streaming communications among dynamically varying sets of tasks. We address this gap by i...

In the U.S.A., 70 percent of the manufactured cement and 43 percent of aggregates is used in Ready-Mixed Concrete (RMC) plants. So a material inventory control system is needed to form a consumption pattern for this material to optimize warehousing cost and ordering in RMC plants. Such a material inventory control system of batching plants could be applied as an approach for optimal estimation ...
