run_oa.py Options

Collect basic data, do markup, and collect refinement data. Then proceed to run analysis on profiling data. This script combines the separate scripts collect.py and analyze.py.

Usage

advisor-python <APM>/run_oa.py <project-dir> [--options] -- <target> [target-options]

NOTE:
Replace <APM> with $APM on Linux* OS or %APM% on Windows* OS.

Options

The following table describes options that you can use with the run_oa.py script. The target application to analyze and application options, if any, must be preceded by two dashes and a space and placed at the end of a command.

Option

Description

<project-dir>

Required. Specify the path to the Intel® Advisor project directory.

-h

--help

Show all script options.

-v <verbose>

--verbose <verbose>

Specify output verbosity level:

  • 1 - Show only error messages. This is the least verbose level.

  • 2 - Show warning and error messages.

  • 3 (default) - Show information, warning, and error messages.

  • 4 - Show debug, information, warning, and error messages. This is the most verbose level.

NOTE:
This option affects the console output, but does not affect logs and report results.

--assume-dependencies (default) | --no-assume-dependencies

Assume that a loop has a dependency if the loop type is not known. When disabled, assume that a loop does not have dependencies if the loop dependency type is unknown.

--assume-hide-taxes [<loop-id> | <file-name>:<line-number>]

Use an optimistic approach to estimate invocation taxes: hide all invocation taxes except the first one.

You can provide a comma-separated list of loop IDs and source locations to hide taxes for. If you do not provide a list, taxes are hidden for all loops.

--assume-never-hide-taxes (default)

Use a pessimistic approach to estimate invocation taxes: do not hide invocation taxes.

--assume-parallel | --no-assume-parallel (default)

Assume that a loop is parallel if the loop type is not known.

--check-profitability (default) | --no-check-profitability

Check the profitability of offloading regions. Only regions that can benefit from the increased speed are added to a report.

When disabled, add all evaluated regions to a report, regardless of the profitability of offloading specific regions.

-c {basic, refinement, full}

--collect {basic, refinement, full}

Specify the type of data to collect for the application:

  • basic - Collect basic performance data (Survey, Trip Counts, FLOP), analyze data transfer between host and device memory, attribute memory objects to loops, and track accesses to stack memory.
  • refinement - Collect refined data (Dependencies) for marked loops only. Do not analyze data transfers.
  • full (default) - Collect both basic data for application and refined data for marked loops, analyze data transfer between host and device memory and potential data reuse, attribute memory objects to loops, and track accesses to stack memory.
NOTE:
For --collect full, make sure to use --data-reuse-analysis and --track-memory-objects.

For --collect basic, make sure to use the --track-memory-objects.

--config <config>

Specify a configuration file by absolute path or name. If you choose the latter, the model configuration directory is searched for the file first, then the current directory.

The following device configurations are available: xehpg_512xve (default), xehpg_256xve , gen12_tgl, gen12_dg1.

NOTE:
You can specify several configurations by using the option more than once.

--cpu-scale-factor <integer>

Assume a host CPU that is faster than the original CPU by the specified value.

All original CPU times are divided by the scale factor.

--data-reuse-analysis (default) | --no-data-reuse-analysis

Estimate data reuse between offloaded regions. Disabling can decrease analysis overhead.

IMPORTANT:
Use with --collect full.

--data-transfer (default) | --no-data-transfer

Analyze data transfer.

NOTE:
Disabling can decrease analysis overhead.

--dry-run

Show the Intel® Advisor CLI commands for advisor appropriate for the specified configuration. No actual collection is performed.

--enable-batching | --disable-batching (default)

Enable job batching for top-level offloads. Emulate the execution of more than one instance simultaneously.

--enable-edram

Enable eDRAM modeling in the memory hierarchy model.

--enable-slm

Enable SLM modeling in the memory hierarchy model. Use both with collect.py and analyze.py.

--exclude-from-report <items-to-exclude>

Specify items to exclude from a report. Available items: memory_objects, sources, call_graph, dependencies, strides.

By default, you can exclude the following items from the report:

  • For the CPU-to-GPU modeling:
    • memory objects
    • sources
    • call graph
    • dependencies
  • For the GPU-to-GPU modeling:
    • memory objects
    • sources

Use this option if your report is heavy weight, for example, due to containing a lot of memory objects or sources, which slows down opening in a browser.

NOTE:
This option affects only data shown in the HTML report and does not affect data collection.

--executable-of-interest <executable-name>

Specify an executable process name to profile if it is not the same as the application to run. Use this option if you run your application via script or other binary.

NOTE:
Specify the name only, not the full path.

--flex-cachesim <cache-configuration>

Use flexible cache simulation to model cache data for several target devices. The flexible cache simulation allows you to change a device for an analysis without recollecting data. By default, when no configuration is set, cache data is simulated for all supported target platforms.

You can also specify a list of cache configurations separated with a forward slash in the format <size_of_level1>:<size_of_level2>:<size_of_level3>. For each memory level size, specify a unit of measure as b - bytes, k- kilobytes, or m - megabytes.

For example, 8k:512k:8m/24k:1m:8m/32k:1536k:8m.

--gpu (recommended) | --profile-gpu | --analyze-gpu-kernels-only

Model performance only for code regions running on a GPU. Use one of the three options.

NOTE:
This is a preview feature. --analyze-gpu-kernels-only is deprecated and will be removed in futire releases.

--ignore <list>

Specify a comma-separated list of runtimes or libraries to ignores time spent in regions from these runtimes and libraries when calculating per-program speedup.

NOTE:
This does not affect estimated speedup of individual offloads.

--include-to-report <items-to-include>

Specify items to include to a report. Available items: memory_objects, sources, call_graph, dependencies, strides.

By default, you can add the following items from the report:

  • For the CPU-to-GPU modeling: strides
  • For the GPU-to-GPU modeling:
    • call graph
    • dependencies
    • strides

Use this option if you want to add more data to the report or see that some data, for example, sources or memory objects, are missing from the report, though you collected this data.

NOTE:
This option affects only data shown in the HTML report and does not affect data collection.

-m [{all, generic, regions, omp, icpx -fsycl, daal, tbb}]

--markup [{all, generic, regions, omp, icpx -fsycl, daal, tbb}]

Mark up loops after survey or other data collection. Use this option to limit the scope of further collections by selecting loops according to a provided parameter:

  • all - Get lists of loop IDs to pass as the option for further collections.

  • generic (default) - Mark up all regions and select the most profitable ones.

  • regions - Select already existing parallel regions.

  • omp - Select outermost loops in OpenMP* regions.

  • icpx -fsycl - Select outermost loops in SYCL regions.

  • daal - Select outermost loops in Intel® oneAPI Data Analytics Library regions.

  • tbb - Select outermost loops in Intel® oneAPI Threading Building Blocks (oneTBB) regions.

omp, icpx -fsycl, or generic selects loops in the project so that the corresponding collection can be run without loop selection options.

You can specify several parameters in a comma-separated list. Loops are selected if they fit any of specified parameters.

--model-system-calls (default) | --no-model-system-calls

Analyze regions with system calls inside. The actual presence of system calls inside a region may reduce model accuracy.

--mpi-rank <mpi-rank>

Specify a MPI rank to analyze if multiple ranks are analyzed.

--no-cache-sources

Disable keeping source code cache within a project.

--no-cachesim

Disable cache simulation during collection. The model assumes 100% hit rate for cache.

NOTE:
Usage decreases analysis overhead.

--no-profile-jit

Disable JIT function analysis.

--no-stacks

Run data collection without collecting data distribution over stacks. You can use this option to reduce overhead at the potential expense of accuracy.

-o <output-dir>

--out-dir <output-dir>

Specify the directory to put all generated files into. By default, results are saved in <advisor-project>/e<NNN>/pp<MMM>/data.0. If you specify an existing directory or absolute path, results are saved in specified directory. The new directory is created if it does not exist.

If you only specify the directory <name>, results are stored in <advisor-project>/e<NNN>/pp<MMM>/<name>.

NOTE:
If you use this options, you might not be able to open the analysis results in the Intel Advisor GUI.

-p <output-name-prefix>

--out-name-prefix <output-name-prefix>

Specify a string to add to the beginning output result filenames.

NOTE:
If you use this options, you might not be able to open the analysis results in the Intel Advisor GUI.

--set-parameter <CLI-config>

Specify a single-line configuration parameter to modify in a format "<group>.<parameter>=<new-value>". For example: "min_required_speed_up=0", "scale.Tiles_per_process=0.5". You can use this option more than once to modify several parameters.

--track-heap-objects (default) | --no-track-heap-objects

Deprecated. Use --track-memory-objects.

--track-memory-objects (default) | --no-track-memory-objects

Attribute heap-allocated objects to the analyzed loops that accessed the objects. Disable to decrease analysis overhead.

IMPORTANT:
Currently, this option affects only the analysis step.

--track-stack-accesses (default) | --no-track-stack-accesses

Track accesses to stack memory.

IMPORTANT:
Currently, this option does not affect the collection.
