Skewed-associativity is a technique that reduces the miss ratios of CPU caches by applying different indexing functions to each way of an associative cache. Even though it showed impressive hit/miss statistics, the scheme has not been welcomed by the industry, presumably because implementation of the original version is complex and might involve access-time penalties among other costs. this work presents a simplified, easy to implement variant that we call 11 niininialli,-skewed-associativity (MSkA). We show that MRA caches, for many cases, should not have penalties in either access time or power consumption when compared to set-associative caches of the same associativity. Hit/miss statistics were obtained by means of trace-driven simulations. Miss ratios are not as good as those for full skewing, but they are still advantageous. Minimal-skewing is thus proposed as a way to improve the hit/miss performance of caches, often without producing access-time delays or increases in power consumption as other techniques do (for example, using higher associativities).

Information services are an integral part of the grid architecture. It is the foundation of how resources are defined and their state known. More importantly, the user of the Grid gets a perspective of what a grid looks like, how it performs and what capabilities it has from information services. the Accelerated Strategic computing Initiative(1) (ASCI) has designed and deployed a set of grid services within the context of the ASCI program. We deploy information services by augmenting the Globus toolkit in order to meet the unique aspects of the ASCI grid. In this paper we describe the decisions made and processes developed to run a grid information service in the ASCI grid.

Computational portal developers often re-implement functionality found in existing portals because there are no common discovery and access mechanisms in place to enable sharing of portal functions. the web services architecture provides an implementation independent, protocol based mechanism for entities to find, share, and invoke remote services. We developed complementary web services at SDSC and IU that generate batch scripts for different batch queuing schedulers.

In systems consisting of multiple clusters of processors such as our Distributed ASCI(1) Supercomputer (DAS), jobs mail request co-allocation, i.e., the simultaneous allocation of processors in different clusters. We simulate such systems ignoring,communication among the tasks of jobs, and determine the,,response times for different types and sizes of job requests';and for different numbers and sizes of clusters. In many cases we also compute or approximate the maximum utilization. We find that the numbers and sizes of the clusters and of the job components have a strong impact on performance, and that in many cases co-allocation is a viable choice.

the research described in this paper is performed as part of the Globus Project. It introduces a new Grid service called InfoGram that combines the ability of serving as information service and as a job execution service. Previously, both services were architected and implemented within the Globus Toolkit as two different services with different wire protocols. Our service demonstrates a significant simplification of the architecture while treating job submissions and information queries alike. the advantage of our service is that it provides backwards compatibility to existing Grid services, while at the same time providing forwards compatibility to the emerging Web services world. Part of the work conducted within this effort is already reused by the current Open Grid Services architecture prototype implementation.

A novel component-based, service-oriented framework for distributed metacomputing is described. Adopting a provider-centric view of resource sharing, this project emphasizes lightweight software infrastructures that maintain minimal state, and interface to current and emerging distributed computing standards. Resource owners host a software backplane onto which owners, clients, or third-party resellers may load components or component-suites that deliver value added services without compromising owner security or control. Standards-based descriptions of services facilitate publication and discovery, via established schemes. the architecture of the container framework, design of components, security and access control schemes, and preliminary experiences are described in this paper.
