WebOct 8, 2015 · Just wanted to add, this NVENC sample was written this way to demonstrate various way that an application might write into the padded GPU input buffer. 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.

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 … WebJan 2, 2012 · 1 Answer. You certainly could use cudaMemcpy to copy pitched device memory, but it would be more usual to use cudaMemcpy2D. An example of a pitched copy from host to device would look something like this: #include "cuda.h" #include typedef float real; int main (void) { cudaFree (0); // Establish context // Host array …
WebAllocating excessive amounts of memory with cuMemAllocHost () may degrade system performance, since it reduces the amount of memory available to the system for paging. As a result, this function is best used sparingly to allocate staging areas for data exchange between host and device. Note all host memory allocated using cuMemHostAlloc () will ...
