Using PC sampling#
PC (Program Counter) sampling service for GPU profiling is a profiling technique to periodically sample the program counter during GPU kernel execution. PC sampling helps in understanding code execution patterns and identifying hotspot(s).
Here are the benefits of using PC sampling:
Identify performance bottlenecks
Understand kernel execution behavior
Analyze code coverage
Find heavily executed code paths
To try out the PC sampling feature, you can use the command-line tool rocprofv3 or the ROCprofiler-SDK library on ROCm 6.4 or later.
Note
PC sampling is ONLY supported on AMD GPUs with architectures gfx90a and later.
PC sampling availability and configuration#
To check if the GPU supports PC sampling, use:
rocprofv3 -L
Or
rocprofv3 --list-avail
The output lists if rocprofv3 supports PC sampling on the GPU and the supported configuration.
List available PC Sample Configurations for node_id 11
Method: ROCPROFILER_PC_SAMPLING_METHOD_HOST_TRAP
Unit: ROCPROFILER_PC_SAMPLING_UNIT_TIME
Minimum_Interval: 1
Maximum_Interval: 18446744073709551615
The preceding output shows that the GPU supports PC sampling with the ROCPROFILER_PC_SAMPLING_METHOD_HOST_TRAP method and the ROCPROFILER_PC_SAMPLING_UNIT_TIME unit. The minimum and maximum intervals are also displayed.
Note
Important firmware fixes to host-trap and stochastic PC-sampling for AMD Instinct MI300X have been made in ROCm 7.0. To ensure that you have the latest fixes, check if you have the correct firmware versions installed:
For host-trap PC-sampling on MI300X: PSP TOS Firmware >= version 00.36.02.59 or 0x00360259 For stochastic PC-sampling on MI300X as described in the following section: MEC Firmware feature version: 50, firmware version >= 0x0000001a
To check the firmware versions, use:
# To check PSP TOS Firmware:
sudo cat /sys/kernel/debug/dri/0/amdgpu_firmware_info | grep SOS
# To check MEC Firmware:
sudo cat /sys/kernel/debug/dri/1/amdgpu_firmware_info | grep MEC
Based on the available PC-sampling configurations, use the following command to profile the application using PC-sampling:
rocprofv3 --pc-sampling-beta-enabled --pc-sampling-method host_trap --pc-sampling-unit time --pc-sampling-interval 1 --output-format csv -- <application_path>
The preceding command enables PC sampling with the host_trap method, time unit, and an interval of 1 μs (microsecond). Replace <application_path> with the path to the application you want to profile.
This generates two files, agent_info.csv and pc_sampling_host_trap.csv. Both files are prefixed with the process ID.
Here are the contents of pc_sampling_host_trap.csv file generated for MatrixTranspose sample application:

For description of the fields in the output file, see PC sampling fields.
If you find the Instruction_Comment field in the output file to be empty, populate this field by compiling your application with debug symbols.
Enabling debug symbols while compiling the application maps back to the source line. This helps in understanding the code execution pattern and hotspots.

PC sampling fields#
Here are the fields in the output file generated by PC sampling:
Sample_Timestamp: Timestamp when sample is generatedExec_Mask: Active SIMD lanes when sampledDispatch_Id: Originating kernel dispatch IDInstruction: Assembly instruction such ass_load_dword s8, s[1:2], 0x10Instruction_Comment: Instruction comment that maps back to the source-line if debug symbols were enabled when application was compiledCorrelation_Id: API launch call ID that matches dispatch ID
To dump samples in a more comprehensive format, use JSON through
--output-format json:
rocprofv3 --pc-sampling-beta-enabled --pc-sampling-method host_trap --pc-sampling-unit time --pc-sampling-interval 1 --output-format json -- <application_path>

Host-trap PC sampling and arbitrary sampling skid#
Host-trap PC sampling is a software-based technique that utilizes a background kernel thread to periodically interrupt running waves to capture the program counter (PC). This method is effective for gathering performance data without requiring specialized hardware to snapshot the waves. However, this method has certain limitations due to the potential delay between receiving and processing the interrupt by the wave to capture the PC. This delay can lead to a sampling skid, where the PC samples might be attributed to the instructions that are up to two instructions away from the actual source of latency. This results in a non-precise intra-kernel sampling method.
When analyzing an application profile generated by host-trap PC sampling, it is important to consider not only the costliest reported instruction but also the instructions immediately preceding or following it. If the costly instruction is near a branch instruction, it is important to consider the instruction targeted by the branch and the one immediately following it as well.
To address the limitations of host-trap sampling, the hardware-based stochastic PC sampling method has been developed. This method provides precise intra-kernel sampling with zero sampling skid, offering more accurate performance insights.
It is important to note that the skid issue inherent in host-trap PC sampling is not likely to be resolved in its current form. Therefore, to achieve more precise performance profiling, it is recommended to adopt stochastic PC sampling starting with the gfx942 architecture.
Note
Host-trap PC sampling is supported on AMD Instinct MI200, MI300, MI325, MI350, and MI355.
Hardware-based (stochastic) PC sampling method#
The ROCPROFILER_PC_SAMPLING_METHOD_STOCHASTIC method has been introduced for the gfx942 architecture.
It employs a specific hardware for probing waves actively running on the GPU.
Besides the information already provided with ROCPROFILER_PC_SAMPLING_METHOD_HOST_TRAP useful for
determining hotspots within the kernel, this method delivers additional information, which helps to determine
whether a sampled wave issued an instruction represented with the specified PC.
If not, this method provides the reason for not issuing the instruction (stall reason).
Such information is particularly useful for understanding stalls during kernel execution.
To use this method on gfx942, it is recommended to list available PC sampling configurations to verify if the latest ROCm stack is installed on the system using:
rocprofv3 -L
An output similar to the following indicates that the ROCPROFILER_PC_SAMPLING_METHOD_STOCHASTIC method is available:
Method: ROCPROFILER_PC_SAMPLING_METHOD_STOCHASTIC
Unit: ROCPROFILER_PC_SAMPLING_UNIT_CYCLES
Minimum_Interval: 256
Maximum_Interval: 2147483648
Note
On gfx942, ROCPROFILER_PC_SAMPLING_METHOD_STOCHASTIC requires intervals to be specified in cycles with values as powers of 2.
To profile an application with ROCPROFILER_PC_SAMPLING_METHOD_STOCHASTIC PC sampling enabled on gfx942, use:
rocprofv3 --pc-sampling-beta-enabled --pc-sampling-method stochastic --pc-sampling-unit cycles --pc-sampling-interval 1048576 --output-format csv, json -- <application_path>
The preceding command serializes samples in both CSV and JSON output formats in the pc_sampling_stochastic.csv and out_results.json files, respectively.
On comparing the pc_sampling_stochastic.csv to pc_sampling_host_trap.csv, you can notice that the ROCPROFILER_PC_SAMPLING_METHOD_STOCHASTIC method
generates the following additional fields:
Wave_Issued_Instruction: Indicates whether the wave issued an instruction represented with the specified PC. Value = 1 for yes and 0 for no.Instruction_Type: If the value ofWave_Issued_Instructionis 1, this field indicates the type of the issued instruction. Otherwise, this field remains irrelevant.Stall_Reason: If the value ofWave_Issued_Instructionis 0, this field indicates the reason for not issuing the instruction (stall reason). Otherwise, this field remains irrelevant.Wave_Count: Total number of waves actively running on a compute unit when the sample is generated.

Fields starting with arb_state_ are of particular interest as they indicate the state of the arbiter at the time of sampling.
For example, arb_state_issue_ fields indicate the type of instructions issued by the arbiter at the time of sampling.
On the other hand, arb_state_stall_ fields indicate the type of instructions stalled at the time of sampling.
This information is useful for understanding how many instructions per cycle (IPC) are issued.
Note
The stochastic PC sampling is supported on AMD Instinct MI300, MI325, MI350, and MI355.
