Lec6 Multicore Programming AshinZ 计算机技术与软件专业技术资格证持证人 为什么会出现多核结构 提高代码的并行性中,很有效的一个方式就是多核结构。时钟频率无法再提高的原因是功率或者说热量。在传统的CMOS芯片中,每个晶体管所需要的能耗与该晶体管驱动的容性负载与电压平方的乘积成正比: 能耗...
GPU的内存架构经过优化,包含多种层次的内存:如共享内存、全局内存和寄存器。这种内存架构使得不同线程可以高效地访问数据,并通过CUDA等工具实现内存优化,从而提高任务执行效率(Run:ai)(CGDirector)。 5.隐藏延迟(Latency Hiding) GPU通过“隐藏延迟”技术减少性能浪费。当某些线程因数据访问延迟而等待时,GPU可以...

2 Mapping an Application to a Multicore Processor Until recently, advances in computing hardware provided significant increases in the execution speed of software with little effort from software developers. The introduction of multicore processors provides a new challenge for software developers, who ...
Multicore processors are now widespread across server, desktop, and laptop hardware. They are also making their way into smaller devices, such as smartphones and tablets. They open new possibilities for concurrent programming because the threads of a process can be executed on several cores in par...
Multicore processors required developers to come up with different algorithms so the hardware improvements could be noticeable, and this was not always easy. The more cores that we have, the harder it is to keep them busy efficiently. SYCL is one of the programming languages that address these...
to scientific calculations. Unlike a traditional CPU, which includes no more than a handful of cores, a GPU has a massively parallel array of integer and floating-point processors, as well as dedicated, high-speed memory. A typical GPU comprises hundreds of these smaller processors (Figure 1)...
Multicore and GPU Programming: An Integrated Approach, Second Edition offers broad coverage of key parallel computing tools, essential for multi-core CPU programming and many-core "massively parallel" computing. Using threads, OpenMP, MPI, CUDA and other state-of-the-art tools, the book teaches ...
