Each kind of memory is associated with its own hardware resource limits, many of which you can find by using cuDeviceGetAttribute. WebA tag already exists with the provided branch name. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior.
WebJun 16, 2011 · The pitch // returned in pPitch by cuMemAllocPitch() is the width in bytes of the // allocation. The intended usage of pitch is as a separate parameter of the // allocation, used to compute addresses within the 2D array. Given the row // and column of an array element of type T, the address is computed as: Bye, Skybuck. 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.
WebCopies from device to host memory. dstHost and srcDevice specify the base pointers of the destination and source, respectively. ByteCount specifies the number of bytes to copy. Note that this function is synchronous. Parameters: dstHost. - Destination host pointer. WebPerform a 2D memory copy according to the parameters specified in pCopy.

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 ...

You certainly could use cudaMemcpy to copy pitched device memory, but it would be more usual to use cudaMemcpy2D.
