Monitoring tools are fundamental components of a development environment as they provide basic support for performance evaluation, debugging, and program visualization. We describe our experiments with several monitoring tools for PVM, namely XPVM, developed at ORNL, Tape/PVM, developed at IMAG Lab, and DAMS, developed at UNL. These tools are compared and their use is described to support instr...

This paper describes an approach to supporting efcient processor virtualization and dynamic load balancing for message-based, parallel programs. Specifically, a user-level process package (UPVM) for SPMD-style PVM applications is presented. UPVM supports light-weight virtual processors that are transparently and independently migratable. It also implements a source-code compatible PVM interface...

With the introduction of high-performance Myrinet interconnection technology, building PVM on top of Myrinet has been a popular tread to improve its communication performance. There are generally two approaches to improve the efficiency of PVM: one approach is to emulate TCP/IP interface in low-level messaging layers, and base PVM on the new TCP/IP stack. The other approach is to redesign and o...

During invasion of an erythrocyte by a malaria merozoite, an indentation develops in the erythrocyte surface at the point of contact between the two cells. This indentation deepens as invasion progresses, until the merozoite is completely surrounded by a membrane known as the parasitophorous vacuole membrane (PVM). We incorporated fluorescent lipophilic probes and phospholipid analogs into the ...

Xab (X-window Analysis and deBugging) is a tool for run time monitoring of PVM (Parallel Virtual Machine) programs. PVM supports the programming of a network of heterogeneous computers as a single parallel computer. Using Xab, PVM programs can easily be instrumented and monitored. Xab uses PVM to monitor PVM programs. This makes Xab very portable but it leads to interesting issues of how to mak...

Pneumonia Virus of Mice (PVM) is the only virus that shares the Pneumovirus genus of the Paramyxoviridae family with Respiratory Syncytial Virus (RSV). A deadly mouse pathogen, PVM has the potential to serve as a robust animal model of RSV infection, since human RSV does not fully replicate the human pathology in mice. Like RSV, PVM also encodes two nonstructural proteins that have been implica...

This paper presents a way to build a computational Grid for PVM programs. The Grid applies Jini to handle the dynamically changing set of participants, and to make the communication between Grid-clients and Grid-machines possible. In case of a PVM-Grid the grid-resources are Parallel Virtual Machines. Our system provides a high-level interface for them, which through the users can submit their ...

During their development within the vertebrate host, Plasmodium parasites infect hepatocytes and red blood cells. Within these cells, parasites are surrounded by a parasitophorous vacuole membrane (PVM). The PVM plays an essential role for the interaction of parasites with their host cells; however, only a limited number of proteins of this membrane have been identified so far. This is partiall...

The paramyxovirus pneumonia virus of mice (PVM) is a rodent model of human respiratory syncytial virus (hRSV) pathogenesis. Here we characterized the PVM-specific CD8(+) T-cell repertoire in susceptible C57BL/6 mice. In total, 15 PVM-specific CD8(+) T-cell epitopes restricted by H-2D(b) and/or H-2K(b) were identified. These data open the door for using widely profiled, genetically manipulated C...

Parallel Virtual Machine (PVM) is a widely{used software system that permits a heterogeneous collection of computers networked together to be viewed by a user's program as a single distributed{memory parallel machine. In this paper, the application of simulation to develop a functional and performance model of the PVM system and PVM applications running in an open workstations environment was i...
