Online visualization of active programs is used to increase a user's understanding of the dynamic processes manifesting a program's behavior. The novel idea presented in this paper applies Virtual Reality techniques to display executing parallel applications. For that reason, the memory of a program is mapped onto different representation, which may even be supported by corresponding sounds, in order to allow the user to feel the program. This allows to distinguish between areas of high activity and non-active parts, which is useful for both, error detection and performance tuning.
