[docs]class Profiler:
r"""
This class to enable the profiling of MindSpore neural networks.
MindSpore users can import the mindspore.Profiler, initialize the Profiler object to start profiling,
and use Profiler.analyse() to stop profiling and analyse the results.
Users can visualize the results using the `MindSpore Insight
<https://www.mindspore.cn/mindinsight/docs/en/r2.2/index.html>`_ tool.
Now, Profiler supports AICORE operator, AICPU operator, HostCPU operator, memory,
correspondence, cluster, etc data analysis.
Args:
output_path (str, optional): Output data path. Default: ``"./data"`` .
op_time (bool, optional): (Ascend/GPU) Whether to collect operators performance data. Default value: ``True``.
profile_communication (bool, optional): (Ascend only) Whether to collect communication performance data in
a multi devices training,collect when True. Setting this parameter has no effect during single device
training. When using this parameter, `op_time` must be set to ``True`` . Default: ``False`` .
profile_memory (bool, optional): (Ascend only) Whether to collect tensor memory data, collect when ``True`` .
When using this parameter, `op_time` must be set to True. Default: ``False`` .
parallel_strategy (bool, optional): (Ascend only) Whether to collect parallel policy performance data.
Default value: ``True`` .
start_profile (bool, optional): The start_profile parameter controls whether to enable or disable performance
data collection based on conditions. Default: ``True`` .
aicore_metrics (int, optional): (Ascend only) Types of AICORE performance data collected, when using this
parameter, `op_time` must be set to ``True`` , and the value must be in [-1, 0, 1, 2, 3, 4, 5],
Default: ``0`` , the data items contained in each metric are as follows:
- -1: Does not collect AICORE data.
- 0: ArithmeticUtilization contains mac_fp16/int8_ratio, vec_fp32/fp16/int32_ratio, vec_misc_ratio etc.
- 1: PipeUtilization contains vec_ratio, mac_ratio, scalar_ratio, mte1/mte2/mte3_ratio, icache_miss_rate
etc.
- 2: Memory contains ub_read/write_bw, l1_read/write_bw, l2_read/write_bw, main_mem_read/write_bw etc.
- 3: MemoryL0 contains l0a_read/write_bw, l0b_read/write_bw, l0c_read/write_bw etc.
- 4: ResourceConflictRatio contains vec_bankgroup/bank/resc_cflt_ratio etc.
- 5: MemoryUB contains ub_read/write_bw_mte, ub_read/write_bw_vector, ub\_/write_bw_scalar etc.
l2_cache (bool, optional): (Ascend only) Whether to collect l2 cache data, collect when True.
Default: ``False`` .
sync_enable (bool, optional): (GPU only) Whether the profiler collects operators in a synchronous way.
Default: ``True`` .
- True: The synchronous way. Before sending the operator to the GPU, the CPU records the start timestamp.
Then the operator is returned to the CPU after execution, and the end timestamp is recorded,
The duration of the operator is the difference between the two timestamps.
- False: The asynchronous way. The duration of the operator is that of sending from the CPU to the GPU.
This method can reduce the impact of adding profiler on overall training time.
data_process (bool, optional): (Ascend/GPU) Whether to collect data to prepare performance data.
Default value: ``True`` .
timeline_limit (int, optional): (Ascend/GPU) Set the maximum storage size of the timeline file (unit M).
When using this parameter, `op_time` must be set to True. Default value: ``500`` .
profile_framework (str, optional): (Ascend/GPU) The host information to collect, it must be one of
["all", "time", "memory", None], When is not set to None, a subdirectory host_info will be generated in the
specified profiler directory, which stores the collected memory and time files on the Host side.
Default: "all".
- "all": Record both host timestamp and host memory usage.
- "time": Only record host timestamp.
- "memory": Only record host memory usage.
- None: Not record host information.
Raises:
RuntimeError: When the version of CANN does not match the version of MindSpore,
MindSpore cannot parse the generated ascend_job_id directory structure.
