XPVM: A graphical console and monitor for PVM
As technology continues to spawn new supercomputing platforms and more powerful workstation environments, it becomes increasingly important to integrate and apply these diverse collections of computers together to extract. the best performance possible. PVM (Parallel Virtual Machine) is gaining wide popularity as a means for realizing the computing power of these heterogeneous systems. PVM is a software package that permits a heterogeneous collection of serial, parallel and vector computers, hooked together by a network, to appear as one large distributed memory computer. One of the primary difficulties in designing applications for distributed computer systems is identifying precisely what is happening inside a program, as multiple threads of control interact to solve a problem. Often it is useful to provide the user with feedback as to the state of the system, including the individual tasks executing on it. XPVM is a graphical interface to PVM that provides such information, to monitor executions and assist in debugging and tuning the performance of PVM programs. XPVM can be used in real time, to observe program activity as it happens, or it can play back saved traces of PVM program executions, for detailed post-mortem analysis.
