Atego's Aonix Perc Ultra 6 virtual machine technology offers support for the Java 6 language and incorporates a compiler for high-speed execution. The technology includes a graphical console, PConsole, to enable live analysis of application execution, in addition to a virtual file system that allows Java application software to manipulate file-like data structures. It has a built-in JavaScript that provides support for other scripting languages.
The technology has replaced the just-in-time and ahead-of-time compilation technology with a LLVM (low level virtual machine) compiler that includes code inlining and efficient dead-code elimination. The graphical console provides visualisation of the execution of the Java application that runs under the virtual machine for monitoring and improvement purposes. It displays real-time graphical information such as information on heap and stack memory and CPU workload of the individual threads. The graphical console also allows individual thread priority and GC parameters to be controlled when the application is running. A Java virtual machine tool interface feature has also been added to provide debug and profiling information.
A unique virtual file system is included in the virtual machine that allows Java application software to manipulate file-like data structures that reside within the Java memory heap. When a virtual file system is mounted, application code can perform operations on the files within it by using the standard classes in the java.io and java.nio packages.
