Pinned memory vector - how to make it?

[andrey-vasenin]

Hi all! How to initialize a host_vector with page-locked memory using thrust? I only can initialize it with cudaMallocHost

Is this approach correct?

#include <thrust/host_vector.h>
#include <thrust/mr/allocator.h>
#include <thrust/system/cuda/memory_resource.h>

typedef thrust::host_vector<char, thrust::mr::stateless_resource_allocator<char,
    thrust::system::cuda::universal_host_pinned_memory_resource> > pinned_hostvec;

int main()
{
    int size = 10;
    pinned_hostvec myvec(size);
}
