We extend GPU Software Transactional Memory to allow threads across many GPUs to access a coherent distributed shared memory space and propose a scheme for GPU-to-GPU communication using CUDA-Aware MPI. The performance of CUDA-DTM is evaluated using a suite of seven irregular memory access bench...

这样来看,bank本身和ram的性质类似,但是整个shared_memory可以看为是多个ram拼接而成 According to the real hardware architecture of SM, SM has multiple warp schedulers. A block will be distributed to a SM, but the unit of execution of SM is warp which has 32 threads. It is easy to understand...
Shared Memory/L1 Cache (共享内存/L1缓存) Register File (寄存器文件) Load/Store Units (加载存储单元) Special Function Units (特殊功能单位) Warp Scheduler(Warp调度器) SM基本架构 GPU中的每个SM都支持数百个线程的并发执行,通常是每个GPU有多个SM,所以有可能有数千个线程并发执行。CUDA采用了SIMT单指令多...
As the prevalence of general purpose computations on GPU, shared memory programming models were proposed to ease the pain of GPU programming. However, with the demanding needs of more intensive workloads, it's desirable to port GPU programs to more scalable distributed memory environment, such as ...
Intel® Threading Building Blocks (Intel® TBB) is a widely used C++ library for shared memory parallel programming and heterogeneous computing (intra-node distributed memory programming). The library provides a wide range of features for parallel programming that include: ...
