  • Creation and management of dynamic virtual organizations The security infrastructure includes a set of services that guarantee the secure operation of the system, providing management of credentials, permissions and resources.

AEM provides job and resource monitoring so that users can get a Linux-like view of their applications. A new experimental feature in this release is the ability to run interactive jobs such as graphical applications unmodifed; harnessing the power of a Grid system. In addition, there is a new graphical tool for editing and managing job submissions. Lasty, grid checkpointing and job migration has been integrated into this version.
