Function cust::memory::cuda_malloc_async

source · [−]

pub unsafe fn cuda_malloc_async<T: DeviceCopy>(
    stream: &Stream, 
    count: usize
) -> CudaResult<DevicePointer<T>>

Expand description

Unsafe wrapper around cuMemAllocAsync which queues a memory allocation operation on a stream. Retains all of the unsafe semantics of cuda_malloc with the extra requirement that the memory must not be used until it is allocated on the stream. Therefore, proper stream ordering semantics must be respected.

Safety

The memory behind the returned pointer must not be used in any way until the allocation actually takes place in the stream.
