shared-memory parallelismThis chapter presents abstractions of shared memory. They represent distributed programming abstractions, which are shared among processes and encapsulate data storage functionality accessible by read and write operations. The memory abstractions are called registers because they resemble...

You can compile your program with the SMP option to generate threaded code that exploits shared-memory parallelism. The SMP option implies the HOT option and an optimization level of OPTIMIZE(2). The following table lists the suboptions of the SMP option. For descriptions and syntax of the sub...

5.1Shared Memory Parallelism From a hardware perspective, a shared memoryparallel architectureis a computer that has a common physical memory accessible to a number of physical processors. The two basic types ofshared memory architecturesareUniform Memory Access(UMA) andNon-Uniform Memory Access(NUMA)...

主要思路是根据shared memory的大小,每次把矩阵乘法的一部分输入数据装入shared memory,完成部分点积运算,结果存储到Pvalue中。经过若干个phases,把所有部分点积运算的结果都累加到Pvalue中,就求出了目标矩阵中某元素的值。具体可以参看图5.5 5.4 Memory As a Limiting Factor to Parallelism...
Shared Memory Concurrency Roadmap 过去很多年, 单核处理器性能基本沿摩尔定律的预测不断提速. 然而, 设计上越来越复杂, 也越来越接近物理极限, 引起了生产成本和功耗的增大, 性价比降低. 2005年前后, CPU制造商, 开始从原来提升单核处理器的ILP(instruction-level parallelism), 转向在单个芯片上增加核数, 挖掘...
