Chakra Replay#

Chakra Replay workload (test_template_name is ChakraReplay) replays execution traces from the Chakra execution trace format for performance analysis and debugging.

Usage Examples#

Test TOML example:

name = "my_chakra_test"
description = "Example Chakra replay test"
test_template_name = "ChakraReplay"

[cmd_args]
trace_path = "/path/to/trace.et"

Test Scenario example:

name = "chakra-replay-test"

[[Tests]]
id = "chakra.1"
num_nodes = 1
time_limit = "00:10:00"

test_name = "my_chakra_test"

Test-in-Scenario example:

name = "chakra-replay-test"

[[Tests]]
id = "chakra.1"
num_nodes = 1
time_limit = "00:10:00"

name = "my_chakra_test"
description = "Example Chakra replay test"
test_template_name = "ChakraReplay"

  [Tests.cmd_args]
  trace_path = "/path/to/trace.et"
