Java Reliable Multicast (JRM) Service can be used by information distribution applications as the transport for delivery of content to very large constituencies. As compared to unicast protocols (i.e., HTTP), reliable multicast enables broadcasting to groups of receivers, ensuring bandwidth conservation and timely delivery. TRAM, a reliable multicast transport protocol developed along with the JRM Service, is designed for high scalability, targeted at very large numbers of receivers. The JRM Service includes new services for multicast address allocation and management of channels, as well as a dynamic filtering mechanism that uses Java software classes which are pushed into the network for the purpose of interpreting the data downstream from the server.
Open Runtime Platform (ORP) is a Java Virtual Machine (JVM) that implements advanced JIT and GC interfaces. These interfaces allow the JIT, GC, and remaining runtime system to be developed in complete isolation and at independent rates. A major benefit is that JIT and GC researchers are relieved of the intractable task of developing a full system before they can innovate in their area of expertise.
The gnu.qif Java package allows you to generate files in the Quicken interchange format (QIF), a text (ASCII) file format that lets you to define transactions. The gnu.qif Java package presents an API that can be used to define accounts and transactions, and to output QIF records.
PennAspect is a software implementation of the two-way aspect model, which is a latent class statistical mixture model for performing soft clustering of co-occurrence data observations. It acts on data such as document/word pairs (words occurring in documents) or movie/people pairs (people see certain movies) to produce their joint distribution estimate. The distribution is packaged as Java source and class files.
