Design And Implementation Issues Of Distributed Shared Memory

In computer science, distributed shared memory DSM is a form of memory architecture where physically separated memories can be addressed as one logically shared address space. Here, the term "shared" does not mean that there is a single centralized memory, but that the address space is "shared" same physical address on two processors refers to the same location in memory. A DSM is essentially a way of seamlessly sharing the physical memories of loosely connected systems. An implementation of a DSM can be Distributed shared memory DSM system is a resource management component of distributed operating system that implements shared memory model in distributed system which have no physically shared memory. The shared memory model provides a virtual address space which is shared by all nodes in a distributed system. The book discusses relevant issues that make the concept of DSM one of the most attractive approaches for building large-scale, high-performance multiprocessor systems.

Issues in the design of distributed shared memory systems

In computer science , distributed shared memory DSM is a form of memory architecture where physically separated memories can be addressed as one logically shared address space. Here, the term "shared" does not mean that there is a single centralized memory, but that the address space is "shared" same physical address on two processors refers to the same location in memory. A distributed-memory system, often called a multicomputer , consists of multiple independent processing nodes with local memory modules which is connected by a general interconnection network. Software DSM systems can be implemented in an operating system , or as a programming library and can be thought of as extensions of the underlying virtual memory architecture. When implemented in the operating system, such systems are transparent to the developer; which means that the underlying distributed memory is completely hidden from the users.

On the Design and Implementation of a Portable DSM System for Low-Cost Multicomputers

Distributed shared memory systems provide an easy-to-program parallel environment, to harness the available computing power of PC networks. We present a layered architecture that allows a portable, scalable, and low-cost implementation that runs on Linux and Windows. Only a few, low-level, modules are operating-system dependent; synchronization, distributed memory and consistency management, as well as multithreading are mostly independent. Preliminary results are encouraging; the Linux port performed well, showing high efficiency.

Может быть, стоит побродить по Триане, кварталу развлечений, и поискать там эту рыжую девицу. Или же обойти все рестораны - вдруг этот тучный немец окажется. Но и то и другое вряд ли к чему-то приведет. В его мозгу все время прокручивались слова Стратмора: Обнаружение этого кольца - вопрос национальной безопасности. Внутренний голос подсказывал Беккеру, что он что-то упустил - нечто очень важное, но он никак не мог сообразить, что .

Хейл подошел к буфету, с грохотом открыл решетчатую дверцу, достал из холодильника пластиковую упаковку тофу, соевого творога, и сунул в рот несколько кусочков белой студенистой массы. Затем облокотился о плиту, поправил широкие серые брюки и крахмальную рубашку. - И долго ты собираешься здесь сидеть. - Всю ночь, - безучастно ответила Сьюзан.
