Performance Checks

Defining Metrics

buildtest provides a method to define test metrics in the buildspecs which can be used to store arbitrary content from the output/error file into named metric. A metric is defined using the metrics property where each element under the metrics property is the name of the metric which must be a unique name. A metric can apply regular expression on stdout, stderr like in this example below. The metrics are captured in the test report which can be queried via buildtest report or buildtest inspect. Shown below is an example where we define two metrics named hpcg_rating and hpcg_state.

buildspecs:
  metric_regex_example:
    executor: generic.local.sh
    type: script
    description: capture result metric from output
    run: echo "HPCG result is VALID with a GFLOP/s rating of=63.6515"
    tags: tutorials
    metrics:
      hpcg_rating:
        type: float
        regex:
          exp: '(\d+\.\d+)$'
          stream: stdout

      hpcg_state:
        type: str
        regex:
          exp: '(VALID)'
          stream: stdout

The metrics will not impact behavior of test, it will only impact the test report. By default a metric will be an empty dictionary if there is no metrics property. If we fail to match a regular expression, the metric will be defined as an empty string.

Note

If your regular expression contains an escape character \ you must surround your string in single quotes ' as pose to double quotes "

Let’s build this test.

We can query the metrics via buildtest report which will display all metrics as a comma separted Key/Value pair. We can use buildtest report --format metrics to extract all metrics for a test. Internally, we store the metrics as a dictionary but when we print them out via buildtest report we join them together into a single string. Shown below is the metrics for the previous build.

You can define a metric based on variables or environment variables which requires you have set vars or env property in the buildspec. The vars and env is a property under the metric name that can be used to reference name of variable or environment variable. If you reference an invalid name, buildtest will assign the metric an empty string. In this next example, we define two metrics gflop and foo that are assigned to variable GFLOPS and environment variable FOO.

Comparison Operators

buildtest supports several comparison operators as part of status check such as >, >=, <=, <, ==, !=. Each metric is compared with a reference value that can be useful when running performance checks. In this section we will cover the following comparison:

Greater Equal

buildtest can determine status check based on performance check. In this next example, we will run the STREAM memory benchmark and capture metrics named copy, scale add and triad from the output and perform an Assertion Greater Equal (assert_ge) with a reference value.

The assert_ge contains a list of assertions where each metric name is referenced via name that is compared with the reference value defined by ref property. The comparison is metric_value >= ref, where metric_value is the value assigned to the metric name captured by the regular expression. The type field in the metric section is used for the type conversion which can be float, int, or string. The item is a numeric field used in match.group to retrieve the output from the regular expression search. The item must be non-negative number.

44          ref: 6000
45        - name: triad
46          ref: 6500

buildtest will evaluate each assertion in the list and use a logical AND to determine the final status of assert_ge.

Let’s build this test, take a close look at the output of buildtest build and take note of the assertion statement.

Assert Equal

buildtest can perform assert equality check with metrics to determine status of test. In this next example, we define four metrics x, y, first, and last which will be compared with its reference value. We introduce a new property assert_eq which is composed of list of assertions. Each reference is converted to its appropriate type (int, float, str).

10      last: Smith

33          item: 1
34      last:
35        type: str
36        regex:
37          stream: stdout
38          exp: '(Smith)$'
39          item: 1
40    status:

This test is expected to pass where all assertions are True. Let’s build the test and see the output

In the next example, we have two tests to highlight some exceptions. In the first test, we define an invalid metric name invalid_metric in assert_eq since this metric was not defined in metrics field, therefore this test will fail. The second test will fail because we have a mismatch in value captured by metric x which is 1 however the reference value is 2.

Assert Not Equal

In this section, we will discuss the inverse equality operation Not Equal check (!=) with reference value.

We can use assert_ne property to perform != check, it works similar to assert_eq with data types int, float and str. In this example, we check the metrics x, y, first and last and each metric should pass. The reference value is converted to the data-type (type field) for each metrics

Assert Range

The assert_range property can be used to test performance for a metric given a lower and upper bound. This property expects one to specify lower and upper field which must be an integer or floating point number to perform comparison. buildtest will perform an assertion, if metric value is in the range specified by lower and upper, then test will pass. Shown below is an example using the assert_range property with stream benchmark.

Note that performance results may vary on your system and depending on the metric value you may want to adjust the lower and upper bound to match your requirement.

Contains and Not Contains

Buildtest can perform status check with a list of reference values and check if metrics value is in the list. The property contains and not_contains can be used to perform this type of check. The ref property is a list of reference values that a metric must have to pass metrics check.

In example below we have two tests, the first test perform contains and not_contains on metrics x. We expect both status check will pass. The second test is expected to fail because metric x will store integer value 1 but the list has string equivalent ‘1’.
