As workstation clusters gain popularity as a parallel computing platform,there is an increasing need for performance tools that support these platforms. Performance prediction is important for performance analysis of scalable parallel applications. Although there are several performance tools available that work with PVM programs,none are capable of performance prediction. We have developed the...

The Genoa Active Message Machine (GAMMA) is a high-performance Active Messages-like communication layer implemented at kernel level as an extension of the Linux Operating System, and made available to user applications through a programming library. On low-cost clusters of Personal Computers (PCs) connected by Fast Ethernet, GAMMA achieves much better communication performance compared to publi...

Myositis ossificans (MO) is a benign condition of non-neoplastic heterotopic bone formation in the muscle or soft tissue. Trauma plays a role in the development of MO, thus, non-traumatic MO is very rare. Although MO may occur anywhere in the body, it is rarely seen in the lumbosacral paravertebral muscle (PVM). Herein, we report a case of non-traumatic MO in the lumbosacral PVM. A 42-year-old ...

Using ammonium bicarbonate (AB) particles as a porogen, chitosan (CS)-based hemostatic porous sponges were prepared in supercritical carbon dioxide due to its low viscosity, small surface tension, and good compatibility with organic solvent. Fourier transform infrared spectroscopy (FTIR) spectra demonstrated that the chemical compositions of CS and poly-(methyl vinyl ether-co-maleic anhydride) ...

he intracellular parasite Toxoplasma gondii hides out in a specialized compartment surrounded by the parasitophorous vacuole membrane (PVM). The PVM associates with host cell organelles, possibly as a way of scavenging lipids from the host cell. On page 95, Sinai and Joiner describe a protein that mediates this association. The new work illuminates a poorly understood aspect of parasite biology...

A simple set of tools can allow inexperienced users to maintain a large PVM system with relative ease. The use of load balancing through the process placement scheme can allow the unobtrusive and efficient use of PVM without complicating the users applications and still allowing them sufficient control. Without using these tools PVM users can cause much disruption to other network users unless ...

The M2-1 protein of respiratory syncytial virus (RSV) is a transcription processivity factor that is essential for virus replication. The function of RSV M2-1 protein can be examined by using an RSVlacZ minigenome assay in vitro since the expression of the lacZ gene is dependent on M2-1. The M2-1 protein of pneumonia virus of mice (PVM), also a member of the Pneumovirus genus, functions poorly ...

This paper describes the implementation of PVM in the new WIN32-bit world. There are no restrictions to existing applications which are using PVM since it is fully compatible to the existing PVM3 release. We discuss the limits and provide some benchmarking results. The software package is freely available at netlib:

Respiratory syncytial virus (RSV) is the leading cause of infant bronchiolitis. The closely related pneumonia virus of mice (PVM) causes a similar immune-mediated disease in mice, which allows an analysis of host factors that lead to severe illness. This project was designed to compare the immune responses to lethal and sublethal doses of PVM strain 15 in Balb/c and C57Bl/6 mice. Balb/c mice ...
