Nonreplicating type I uracil auxotrophic mutants of Toxoplasma gondii possess a potent ability to activate therapeutic immunity to established solid tumors by reversing immune suppression in the tumor microenvironment. Here we engineered targeted deletions of parasite secreted effector proteins using a genetically tractable Δku80 vaccine strain to show that the secretion of specific rhoptry (RO...

We present a communication library to improve performance of PVM. The new library introduces communication primitives based on Active Messages. We propose a hybrid scheme that includes a signal driven message notiication scheme plus controlled polling. The new communication library is tested along with the normal PVM library to assess the improvement in performance.

We examine the differences between two message passing environments, PVM and Parix, and their impact on the implementation of applications. We outline Ensemble, a methodology for designing and implementing message passing applications by providing common software architecture. We outline Ensemble applied to PVM and Parix. We describe the mechanical porting of applications developed under Ensemb...

A recent study reports that habit formation in consumption can improve the ability of the present value model of the current account (PVM) to forecast actual current account movements because habits make the current account more volatile. This paper, however, shows that the habit-forming PVM is observationally equivalent to the canonical PVM augmented with a transitory consumption shock: the sa...

ion it ranges between PVM-Prolog which is a pure paradigm extendedby message passing and a high-level multi-agent language such as vivid agents.7.3 ICEICE [Amt95, AB96] de nes a model to support distributed AI applications overhybrid languages and heterogeneous, distributed platforms. It is available fromProlog, Lisp, C, C++ and Tcl/Tk and is, similar to PVM-Prolog, implemen...

Due to the increasing popularity of networked clusters of workstations and the need for portability across various parallel and distributed platforms, a number of programming environments have been proposed to develop parallel programs. Express and PVM are two such commonly used environments that are available on most commercial parallel computers as well as a variety of clusters of workstation...
