The pitch returned by cuMemAllocPitch() is guaranteed to work with cuMemcpy2D() under all circumstances. For allocations of 2D arrays, it is recommended that programmers consider performing pitch allocations using cuMemAllocPitch().Due to alignment restrictions in the hardware, this is especially true if the application will be performing 2D memory copies between different regions of device ... WebDec 12, 2010 · Hi, I have been reading the programming guide for CUDA and came across these two different methods of memory management. I wanted to clarify the difference between cuArrayCreate and cuMemAllocPitch. Is cuArrayCreate used to create an array in which each element might be a set of 1,2 or 4 elements, as opposed to a simple linear …

NVIDIA CUDA Library: cuMemcpyDtoD

WebAllocates bytesize bytes of host memory that is page-locked and accessible to the device. The driver tracks the virtual memory ranges allocated with this function and automatically accelerates calls to functions such as cuMemcpyHtoD().Since the memory can be accessed directly by the device, it can be read or written with much higher bandwidth than … WebNote that this function infers the type of the transfer (host to host, host to device, device to device, or device to host) from the pointer values. This function is only allowed in contexts which support unified addressing. Note that this function is asynchronous and can optionally be associated to a stream by passing a non-zero hStream argument. WebIf srcMemoryType is CU_MEMORYTYPE_HOST, srcHost and srcPitch specify the (host) base address of the source data and the bytes per row to apply. srcArray is ignored. If srcMemoryType is CU_MEMORYTYPE_DEVICE, srcDevice and srcPitch specify the (device) base address of the source data and the bytes per row to apply. srcArray is … summary of phil by alan shipnuck

One can use cuMemcpy2D for host-to-device /w padding, or cuMemcpyHtoD for transfers, or use a CUDA kernel to write data into buffer. This is what the sample demonstrates.
