CLUMEQ is a supercomputing consortium of universities in the province of Quebec, Canada. It includes McGill University, Universite Laval, and all nine components of the Universite du Quebec network. CLUMEQ supports scientific research in disciplines such as climate and ecosystems modeling, high energy particle physics, cosmology, nanomaterials, supramolecular modeling, bioinformatics, biophotonics, fluid dynamics, data mining and intelligent systems. Sun is providing the technology for this HPC implementation.
Berlin-based myToys.de is a retail company that sells merchandise for children and their families. Distributing its goods online, in stores, and through a mail-order catalog, the company initially relied on Linux for most of its computing systems. In time, the IT environment at myToys.de became heterogeneous and support became an issue. To increase system security and receive technical support, myToys.de replaced its Web site and order-processing system from multiple manufacturers with a new infrastructure based on Sun SPARC Enterprise servers, StorageTek storage systems, software, and technical support services.
A database study comparing the performance of storage architectures using Sun Storage F5100 Flash Array and storage architecture based only on traditional hard disks was recently conducted, and its results presented by Chang Shu. Both atomic queries such as sorts / joins, and advanced queries containing complex business logic were tested in order to observe the performance gains in using F5100 Flash Array.
Sun engineers have been working with the open source software Terracotta to optimize its technology on Sun solutions. Terracotta is an open-source product, entirely written in Java code, that simplifies scalability for Java applications by synchronizing user defined subsets of Java heap across multiple Virtual Machines for the Java platform (Java Virtual Machine or JVM) on different physical machines. A four-page PDF offers an overview of the business benefits of Terracotta for Java developers, plus some results of testing the team did with Terracotta on both x64 and CMT servers, reports George Drapeau.
