With the introduction of the high-frequency IBM System z10e processor design, a new, robust cache hierarchy was needed to enable up to 80 of these processors aggregated into a tightly coupled symmetric multiprocessor (SMP) system to reach their performance potential. Typically, each time the processor frequency increases by a significant factor, as did the z10e processor over the predecessor IB...

key distribution is an important problem in wireless sensor networks where sensor nodesare randomly scattered in adversarial environments.due to the random deployment of sensors, a list of keys must be pre-distributed to each sensor node before deployment. to establish a secure communication, two nodes must share common key from their key-rings. otherwise, they can find a key- path in which ens...

While the subject of SMP locking primitives has been well covered in the literature [Val][Schm][Bald][Leh], there has been relatively little discussion on the rationale and process behind the application of these locking primitives. This leads to an inverted problem where the bulk of the work in making a kernel SMP-safe lies above the locking primitives, yet there is little guidance on how and ...

National Institute of Standards and Technology, Gaithersburg, MD 20899-0001 In 1997, the National Institute of Standards and Technology (NIST) initiated a process to select a symmetric-key encryption algorithm to be used to protect sensitive (unclassified) Federal information in furtherance of NIST’s statutory responsibilities. In 1998, NIST announced the acceptance of 15 candidate algorithms a...

A divisible design graph is a graph whose adjacency matrix is the incidence matrix of a divisible design. Divisible design graphs are a natural generalization of (v, k, λ)-graphs, and like (v, k, λ)-graphs they make a link between combinatorial design theory and algebraic graph theory. The study of divisible design graphs benefits from, and contributes to, both parts. Using information of the e...

In this paper we study curvature properties of semi - symmetric type of totally umbilical radical transversal lightlike hypersurfaces $(M,g)$ and $(M,widetilde g)$ of a K"ahler-Norden manifold $(overline M,overline J,overline g,overline { widetilde g})$ of constant totally real sectional curvatures $overline nu$ and $overline {widetilde nu}$ ($g$ and $widetilde g$ are the induced metrics on $M$...

in the first part of this paper, some theorems are given for a riemannian manifold with semi-symmetric metric connection. in the second part of it, some special vector fields, for example, torse-forming vector fields, recurrent vector fields and concurrent vector fields are examined in this manifold. we obtain some properties of this manifold having the vectors mentioned above.

Restoring and non-restoring divider has become widely applicability in the era of digital computing application due to its computation speed. In this paper, we have proposed the design of divider of different architecture for the computation of Vedic sutra based. The design of divider in the Vedic mode results in high computation throughput due to its replica architecture, where latency is mini...

The present study proposes novel micro-jet impingement heat sink with effusion holes for flow extraction. The design consists of impingement nozzles surrounded by multiple effusion holes to take away the spent fluid. A three-dimensional numerical model is used for steady, incompressible, laminar flow and conjugate heat transfer for the performance analysis of the proposed design. The computatio...
