CUresult cuMemcpyPeer ( CUdeviceptr  dstDevice, CUcontext  dstContext, CUdeviceptr  srcDevice, CUcontext  srcContext, size_t  ByteCount   ) Copies from device memory in one context to device memory in another context. dstDevice is the base device pointer of the destination memory and dstContext is the destination context. srcDevice is the base device pointer of the source memory and srcContext is the source pointer. ByteCount specifies the number of bytes to copy. Note that this function is asynchronous with respect to the host, but serialized with respect all pending and future asynchronous work in to the current context, srcContext, and dstContext (use cuMemcpyPeerAsync to avoid this synchronization). Parameters: dstDevice  - Destination device pointer dstContext  - Destination context srcDevice  - Source device pointer srcContext  - Source context ByteCount  - Size of memory copy in bytes Returns: CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUE Note: Note that this function may also return error codes from previous, asynchronous launches.
