A tagged union describing different resources identified by the type field. This structure should not be directly modified outside of the API that created it.

‎ struct {
           enum cudaDevResourceType 
               type;
           union {
               struct cudaDevSmResource 
               sm;
               struct cudaDevWorkqueueConfigResource 
               wqConfig;
               struct cudaDevWorkqueueResource 
               wq;
           };
       };

• If type is cudaDevResourceTypeInvalid, this resoure is not valid and cannot be further accessed.

• If type is cudaDevResourceTypeSm, the cudaDevSmResource structure sm is filled in. For example, sm.smCount will reflect the amount of streaming multiprocessors available in this resource.

• If type is cudaDevResourceTypeWorkqueueConfig, the cudaDevWorkqueueConfigResource structure wqConfig is filled in.

• If type is cudaDevResourceTypeWorkqueue, the cudaDevWorkqueueResource structure wq is filled in.
