- 作用:CUDAMemcpy2DAsync()函数中的dst参数用于指定内存拷贝的目标位置区域。在使用该参数时,需要保证目标位置区域指针所指向的内存空间足够大,能够存储从源位置区域复制过来的数据。 10. dpitch: 目标内存区域的行字节数 - 说明:目标内存区域的行字节数 - 类型:size_t - 作用:dpitch参数用于确定目标内存区域每...
请问aclrtMemcpyAsync 对于host内存(非aclrtMallocHost申请) 到device内存拷贝是同步还是异步?对于cudaMemcpyAsync 而言,从 host -> device 进行内存拷贝,存在两种现象:host内存为pinned memory (页锁定内存),即由 cudaMallocHost 申请的内存,则cudaMemcpyAsync为异步; host内存为“可换页内存”,即由普通的malloc申请的...
Hello everyone, I’m currently exploring the new asynchronous memory copy feature on an RTX 3050 laptop running Windows 11 with Microsoft Visual Studio version 19.29.30152. Specifically, I’m attempting to implement memcpy…
cudamemcpytosymbolasync 是CUDA 运行时库中的一个函数,用于异步地将数据从主机(CPU)内存或设备(GPU)内存复制到设备符号(通常是全局变量或常量内存)中。与 cudamemcpy 不同,cudamemcpytosymbolasync 是专门用于与设备符号交互的,并且它是异步执行的,不会阻塞主机线程。

2、并不是只要一调用hipMemcpyAsync就会出现卡死的现象,在卡死现象出现前调用了若干次hipMemcpyAsync,并没有出现卡死的现象。3、尝试在调用hipMemcpyAsync之前调用hipStreamSynchronize,主机端线程会卡死在hipStreamSynchronize,并且在hipStreamSynchronize前调用hipGetLastError,并没有发现错误。
