struct
ripple::Topology¶ The Topology struct stores information about the topology of the system.
It holds information about the caches, processors, processor mapping, gpu devies, etc, which can be used to optimally partiion parallel algorithms.
Public Functions
-
Topology() noexcept¶ Constructor to create the topology.
-
auto
num_gpus() const noexcept -> size_t¶ Gets the number of gpus in the system.
- Return
The total number of gpus in the system.
-
auto
num_cores() const noexcept -> size_t¶ Gets the number of cpu cores for the system.
- Return
The number of independent cpu cores in the system.
-
auto
combined_gpu_memory() const noexcept -> uint64_t¶ Calculates the total number of bytes of memory available from all gpus.
- Return
The total number of bytes of gpu memory in the system.
-
auto
combined_gpu_memory_gb() const noexcept -> float¶ Calculates the total number of gigabytes of memory available from all gpus.
- Return
The total number of gigabytes of gpu memory in the system.
-
auto
device_to_device_available(size_t gpu_id1, size_t gpu_id2) const noexcept -> bool¶ Determines if peer to peer access is possible between two gpus.
- Return
true if peer to peer is possible between the gpus.
- Parameters
size_t: gpu_id1 The index of the first gpu.size_t: gpu_id2 The index of the second gpu.
