Stores the properties of an agent (CPU, GPU, etc.)
The node_id
member is the KFD topology node id. It should be considered the "universal" indexing number. It is equivalent to the HSA-runtime HSA_AMD_AGENT_INFO_DRIVER_NODE_ID property of a hsa_agent_t
. The const char*
fields (name
, vendor_name
, etc.) are guaranteed to be valid pointers to null-terminated strings during tool finalization. Pointers to the agents via
- See also
- rocprofiler_query_available_agents are constant and will not be deallocated until after tool finalization. Making copies of the agent struct is also valid.

---|---|---|
uint32_t | array_count | Number of SIMD arrays. |

uint32_t | cu_per_engine | computed |
uint32_t | cu_per_simd_array | Number of Compute Units (CU) per SIMD array. |

int32_t | logical_node_type_id |
Logical sequence number with respect to other agents of same type. This will always be [0..N) where N is the total number of X agents (where X is a rocprofiler_agent_type_t value). This field is intended to help with environment variable indexing used to mask GPUs at runtime (i.e. HIP_VISIBLE_DEVICES and ROCR_VISIBLE_DEVICES) which start at zero and only apply to GPUs, e.g., logical_node_type_id value for first GPU will be 0, second GPU will have value of 1, etc., regardless of however many agents of a different type preceeded (and thus increased the node_id or logical_node_id). Example: a system with 2 CPUs and 2 GPUs, where the node ids are 0=CPU, 1=GPU, 2=CPU, 3=GPU, then then CPU node_ids 0 and 2 would have logical_node_type_id values of 0 and 1, respectively, and GPU node_ids 1 and 3 would also have logical_node_type_id values of 0 and 1. |
