Detailed Description

Resource that adapts an upstream resource to be thread safe.

An instance of this resource can be constructed with an existing, upstream resource in order to satisfy allocation requests. This adaptor wraps allocations and deallocations from the upstream in a mutex lock.

This class is copyable and shares ownership of its internal state via cuda::mr::shared_resource.

Constructor & Destructor Documentation

explicit

Construct a new thread safe resource adaptor using upstream to satisfy allocation requests.

Parameters

upstream

The resource used for allocating/deallocating device memory.
