7.2. cudaAccessPolicyWindow Struct Reference
[Data types used by CUDA Runtime]
Specifies an access policy for a window, a contiguous extent of memory beginning at base_ptr and ending at base_ptr + num_bytes. Partition into many segments and assign segments such that. sum of "hit segments" / window == approx. ratio. sum of "miss segments" / window == approx 1-ratio. Segments and ratio specifications are fitted to the capabilities of the architecture. Accesses in a hit segment apply the hitProp access policy. Accesses in a miss segment apply the missProp access policy.
Public Variables
- void * base_ptr
- enumcudaAccessProperty hitProp
- float hitRatio
- enumcudaAccessProperty missProp
- size_t num_bytes
Variables
- void * cudaAccessPolicyWindow::base_ptr [inherited]
-
Starting address of the access policy window. CUDA driver may align it.
- enumcudaAccessPropertycudaAccessPolicyWindow::hitProp [inherited]
-
CUaccessProperty set for hit.
- float cudaAccessPolicyWindow::hitRatio [inherited]
-
hitRatio specifies percentage of lines assigned hitProp, rest are assigned missProp.
- enumcudaAccessPropertycudaAccessPolicyWindow::missProp [inherited]
-
CUaccessProperty set for miss. Must be either NORMAL or STREAMING.
- size_t cudaAccessPolicyWindow::num_bytes [inherited]
-
Size in bytes of the window policy. CUDA driver may restrict the maximum size and alignment.
