Application scalability and Java HPC
Java High Performance Computing (HPC ) refers to the ability of an application to handle different levels of usage. A highly scalable application will only require additional resources in order to handle higher usage loads. An application that is not scalable will require modifications to the application itself in order to handle higher usage loads. Java HPC allows a program to handle different loads, but may limit application performance and functionality. In this section on Java HPC, get the latest news, research and tutorials to help make your applications fit your business needs.
