Support for flexible and transparent distributed computing
Modern distributed computing developed from the traditional supercomputing community rooted firmly in the culture of batch management. Therefore, the field has been dominated by queuing-based resource managers and work flow based job submission environments where static resource demands needed be determined and reserved prior to launching executions. This has made it difficult to support resour...
متن کاملTransparent Latecomer Support for Synchronous Groupware
In a collaborative session users may join and leave. A user who joins a session is called a latecomer. A latecomer needs the current state of the collaborative session to participate in the session. There exist different approaches to accommodate a latecomer. The runtime system can, e.g., transfer the state to the latecomer or replay how the session state was reached. If the state is maintained...
متن کاملOODB support for providing transparent schema changes
Schema updates on shared object-oriented databases (OODBs) are almost always prohibited because of the risk of making existing application programs obsolete when run against the modiied schema. We have proposed a solution approach, called Transparent Schema Evolution (TSE), that successfully addresses this problem by integrating schema evolution capabilities with object-oriented view facilities...
متن کاملToward Automated Support for Transparent Interoperable Queries
Many object-oriented databases (OODBs) are based on programming languages (such as C++, CLOS and Smalltalk) that pre-date Java. Given Java’s rapid emergence, there is a growing need for interoperating existing or legacy OODBs with new applications that require Java. Unfortunately, there are few mechanisms that allow software developers to easily integrate Java applications with non-Java OODBs. ...
متن کاملTransparent Support for Wait-Free Transactions
This paper concerns software support for non-blocking transactions in shared-memory multiprocessors. We present mechanisms that convert sequential transactions into lock-free or wait-free ones. In contrast to some previous mechanisms, ours support transactions for which the set of memory locations accessed cannot be determined in advance. Our implementations automatically detect and resolve con...
