CUDA中给出了这两个抽象单元:拷贝引擎(Copy Engine)和 计算引擎(Kernel Engine),这两个引擎在支持异步运算, 比如我们需要完成矩阵乘法运算C = A x B,一般流程如下所示(假设拷贝与运算都是消耗一个单位时间): 该示例中运算由单stream完成,数据拷贝与运算是按照代码给定顺序进行,图中两个矩阵运算的也会依次进行,...

CUDA的微架构(Micro-architecture)一般指的是Streaming Multiprocessor(简称SM)的架构,并不包括外围的一些辅助功能,比如memory控制单元,copy engine之类。指令集(Instruction Set Architecture,简称ISA)就不用解释了,就是GPU执行的机器码的形式。CUDA的机器码也被称为SASS,有人说是Streaming ASSembly,存疑。CUDA还有另外一...

deviceOverlap is 1 if the device can concurrently copy memory between host and device while executing a kernel, or 0 if not. Deprecated, use instead asyncEngineCount. multiProcessorCount is the number of multiprocessors on the device. kernelExecTimeoutEnabled is 1 if there is a run time lim...

一些设备可以在内核执行的同时执行与 GPU 之间的异步内存复制。 应用程序可以通过检查asyncEngineCount设备属性(请参阅设备枚举)来查询此功能,对于支持它的设备,该属性大于零。 如果复制中涉及主机内存,则它必须是页锁定的。 还可以与内核执行(在支持concurrentKernels设备属性的设备上)或与设备之间的拷贝(对于支持async...
