Massively Multi-Core Systems and Virtual Memory

چکیده
The fundamental limits imposed by semiconductor technology have led to renewed interest in parallel computation, in order to achieve the maximum performance and energy efficiency of massively parallel computer systems. We believe this can be done by extending the virtual memory concept to the domain of parallel processing. First, we explain why virtual memory is essential for massive parallel computing in the age of many-core chip technology. We claim it is desirable and feasible to build an efficient Multicore Operating System that implements a global virtual memory using a codelet based runtime system. Finally, we explain how a codelet based programming model can be supported with modified system architecture to yield high performance and energy efficiency with the benefits of global virtual memory.

متن کاملNP-Completeness of Memory-Aware Virtual Machine Scheduling Problem
Increasing energy consumption in server consolidation environments leads to high maintenance costs for data centers. Main memory, no less than processor, is a major energy consumer in this environment. This paper proposes a problem of reducing memory energy consumption using virtual machine scheduling in multi-core systems. We prove that scheduling virtual machines to minimize the memory energy...
متن کاملGraph Coloring Algorithms for Muti-core and Massively Multithreaded Architectures
We explore the interplay between architectures and algorithm design in the context of shared-memory platforms and a specific graph problem of central importance in scientific and high-performance computing, distance-1 graph coloring. We introduce two different kinds of multithreaded heuristic algorithms for the stated, NP-hard, problem. The first algorithm relies on speculation and iteration, a...
متن کاملA JVM for the Barrelfish Operating System
Barrelfish is a research operating system based on the Multikernel model, an OS structure that treats heterogeneous multi-core systems as a network of independent nodes communicating via message-passing. Arguably, such a system can benefit from high-level programming models such as the Java Virtual Machine, since they can provide a singlesystem image and facilitate migration of threads between ...
