Namespaces | |
| cuda | |
| Definitions and functionality wrapping CUDA APIs. | |
| cuda::device | |
| Definitions and functionality related to CUDA devices (not including the device wrapper type cuda::device_t itself) | |
| cuda::device::peer_to_peer | |
| API functions and definitions relating to communications among peer CUDA GPU devices on the same system. | |
| cuda::context::peer_to_peer | |
| API functions and definitions relating to communications among "peer" contexts on the same system, which may possibly regard different CUDA devices. | |
Functions | |
| void | cuda::context::current::peer_to_peer::enable_access_to (const context_t &peer_context) |
| Allows subsequently-executed memory operations and kernels to access the memory associated with the specified peer context - if peer-to-peer access is supported between the two devices. | |
| void | cuda::context::current::peer_to_peer::disable_access_to (const context_t &peer_context) |
| Prevents subsequently-executed memory operations and kernels from accessing the memory associated with the specified peer context - if peer-to-peer access is supported between the two devices. | |
| bool | cuda::context::peer_to_peer::can_access (context_t accessor, context_t peer) |
| Check if a CUDA context can access the global memory of another CUDA context. | |
| void | cuda::context::peer_to_peer::enable_access (context_t accessor, context_t peer) |
| Enable access by one CUDA device to the global memory of another. More... | |
| void | cuda::context::peer_to_peer::disable_access (context_t accessor, context_t peer) |
| Disable access by one CUDA device to the global memory of another. More... | |
| void | cuda::context::peer_to_peer::enable_bidirectional_access (context_t first, context_t second) |
Enable access both by the first to the second context and the other way around. | |
| void | cuda::context::peer_to_peer::disable_bidirectional_access (context_t first, context_t second) |
Disable access both by the first to the second context and the other way around. | |
| bool | cuda::device::peer_to_peer::can_access (const device_t &accessor, const device_t &peer) |
| Determine whether one CUDA device can access the global memory of another CUDA device. More... | |

| Determine whether two CUDA devices can currently access each other. | |
| void | cuda::device::peer_to_peer::enable_bidirectional_access (const device_t &first, const device_t &second) |
Enable access both by the first to the second device and the other way around. | |
| void | cuda::device::peer_to_peer::disable_bidirectional_access (const device_t &first, const device_t &second) |
