However, programming with non-blocking asynchronous communication necessitates explicit manipulation of continuation which may be very tedious and error-prone [5]. On the other hand, blocking asynchronous communications or call/return communication abstractions, such as ask [11], now [17] and request [3], eliminate the need for explicit continuation manipulation to ease the task of programming; they allow an object to invoke a method on a remote object and use the value returned by the object. For example an object x can execute the following statement..

Modular Specification of Partitioning and Distribution Strategies
No full textWe illustrate the use of our language support for parallel algorithms based on irregular structures which may require dynamic adjustment of load across processors. A fast runtime kernel is used to run the programs on CM-5. In spite of the ease of programming offered by the language, the portability and modularity of the code and the small size of the programs, reasonable efficiency is obtained.Made available in DSpace on 2015-09-25T20:20:52Z (GMT).

Partitioning and Distribution Strategies as First Class Objects
No full textIn scalable concurrent architectures, the performance of a parallel algorithm depends on the resource management policies used. Such policies determine, for example, how data is partitioned and distributed and how processes are scheduled. For different problem sizes or architectures, different policies may be more efficient. In particular, the performance of a parallel algorithm obtained by using a particular policy can be The research described has been made possible by support from the Office of Naval Research (ONR contract numbers N00014-90-J-1899 and N00014-93-1-0273), by an Incentives for Excellence Award from the Digital Equipment Corporation Faculty Program, and by joint support from the Defense Advanced Research Projects Agency and the National Science Foundation (NSF CCR 90-07195). y The authors thank the referees for providing several constructive suggestions.

Physiological functions of multidrug transporters in yeast
No full textOverexpression of drug extrusion pumps belonging to the ABC (ATP-binding cassette) super family of proteins is one of the most common mechanisms of multidrug resistance in various organisms. Both pathogenic and non-pathogenic yeast cells also become resistant to a variety of drugs by overexpressing genes encoding ABC drug efflux pumps. Recent evidences reveal that not only the well-characterized human drug extrusion pump (MDR1/P-gp), but its close homologues in yeast also mediate several cellular functions. Keeping in view the importance of ABC drug transporters in yeasts, this review particularly focuses on their physiological roles

No full textIn view of the increasing threat posed by fungal infections in immunocompromised patients and due to the non-availability of effective treatments, it has become imperative to find novel antifungals and vigorously search for new drug targets. Fungal pathogens acquire resistance to drugs (antifungal), as well-established phenomenon termed multidrug resistance (MDR), which tampers effective treatment strategies. The MDR phenomenon is spread throughout the evolutionary scale. Accordingly, a host of responsible gene have been identified in the genetically tractable yeast Saccharomyces cerevisiae, as well as a pathogenic yeast Candida albicans. Studies so far suggest that while antifungal resistance is the culmination of multiple factors, there may be a unifying mechanism of drug resistance in these pathogens. ABC (ATP binding cassette) and MFS (major facilitator superfamily) drug transporters belonging to two different superfamilies, are the most prominent contributors to MDR in yeasts. Considering the abundance of the drug transporters and their wider specificity, it is believed that these drug transporters may not exclusively export drugs in fungi. It has become apparent that the drug transporters of the ABC superfamily of S. cerevisiae and C. albicans are multifunctional proteins, which mediate important physiological functions. This review summarizes current research on the molecular mechanisms underlying drug resistance, the emerging regulatory circuits of MDR genes, and the physiological relevance of drug transporters
