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,...
Texture alignment: zu bytes Concurrent copy and kernel execution: Yes with 5 copy engine(s) Run time limit on kernels: Yes Integrated GPU sharing Host Memory: No Support host page-locked memory mapping: Yes Alignment requirement for Surfaces: Yes Device has ECC support: Disabled CUDA Device Dri...
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...
Texture alignment: 512 bytes Concurrent copy and kernel execution: Yes with 2 copy engine(s) Run time limit on kernels: No Integrated GPU sharing Host Memory: No Support host page-locked memory mapping: Yes Alignment requirement for Surfaces: Yes Device has ECC support: Disabled Device supports ...
为了确保 CUDA 的独特类型可以在 Unreal Engine 4 上毫无问题地使用,所以我制作了 addWithCuda2,它除了 addWithCuda 之外还使用 int4 类型。 当然,剪掉头文件也是必要的。 kernel.cu file hljs code #include"cuda_lib_test.h"__global__voidaddKernel(int* c,constint* a,constint* b) ...
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...
For example, the asyncEngineCount field of the device property structure indicates whether overlapping kernel execution and data transfers is possible (and, if so, how many concurrent transfers are possible); likewise, the canMapHostMemory field indicates whether zero-copy data transfers can be ...
