1(b) and 10. 1(c), only 10. 1(b) is permitted if overtaking is not allowed. Please note, even if overtaking between processes is not allowed, there is still the possibility for two messages to indirectly overtake, as in figure 10. 1(d). However, due to the possible use of the wild card a receive may still introduce nondeterministic behavior. At wild card receives two or more messages might race and the order of their arrival may alter subsequent computations. In contrast to message overtaking, this behavior may even be anticipated for several reasons, e.

The solution for this was to write a Java servlet that has a suitable login and password for approved users. Later on, this should turn into a policy enforcement API within the virtual machine design itself. 5 HIGH PERFORMANCE COMPUTING SYSTEMS AND APPLICATIONS CONCLUSIONS In this paper we have outlined the essential features of a virtual laboratory. Examples of such advanced software systems exist, though in early stages of development. Our group at Windsor is currently involved in designing and constructing a system called VPMS.

Keywords: Testing, debugging, nondeterminism, race conditions. 1 INTRODUCTION Parallel computing on high performance architectures is applied whenever big problems or grand challenges are concerned.
