Computer science Scheduling Memory Transactions in Distributed Systems VIRGINIA POLYTECHNIC INSTITUTE AND STATE UNIVERSITY Binoy Ravindran KimJunwhanDistributed transactional memory (DTM) is an emerging, alternative concurrency control model that promises to alleviate the difficulties of lock-based distributed ...
In compile-time task scheduling for distributed-memory systems, list scheduling is generally accepted as an attractive approach since it pairs low cost with good results. List scheduling algorithms schedule tasks in order of their priority. This priority can be computed either 1) statically, before ...
Whenever the CPU becomes idle, the operating system must select one of the processes in the line ready for launch. The selection process is done by a temporary (CPU) scheduler. The Scheduler selects between memory processes ready to launch and assigns the CPU to one of them. 进程是程序的实...
The amount of memory at the processors participating in the computation is too small to accommodate the whole load at any moment of time. Therefore, the load is distributed in many small installments. Memory reservations have block nature, by which we depart from earlier models simplifying the ...

Although for traditional distributed systems (with CPUs) this requirement is usually neglected, due to possible allo- cation in virtual memory address space, this can not be assumed for accelerators in desktop systems, such as GPUs. Therefore, we characterize the application by input, output and ...
Second, to optimize system throughput, PAR-BS employs a parallelism-aware DRAM scheduling policy that aims to process requests from a thread in parallel in the DRAM banks, thereby reducing the memory-related stall-time experienced by the thread. PAR-BS seamlessly incorporates ...
Processor scheduling in multiprocessor systems can be divided into two steps. The first step, referred to as the processor allocation problem, is to determine the number of processors to be allocated to a job so as to maximize the system throughput and p
For example, memory is comparatively expensive in terms of chip area and may therefore be a limitation in many applications. Generally, power consumption is the major limiting factor, but we will choose to minimize the amount of hardware resources (i.e., the number of PEs, memories, and ...
