Memory Latency Checker (MLC) Workload Profiles

The following profiles run customer-representative and benchmarking scenarios using the Intel Memory Latency Checker(MLC) workload.

PERF-MEM-LATENCY.json​

Runs the MemoryLatencyChecker workload to measure memory latency and bandwidths against increasing load.

  • Workload Profile

  • Supported Platform/Architectures

    • linux-x64
    • win-x64

  • Supported Operating Systems

    • Azure Linux 3, 4
    • Ubuntu 20.04, 22.04, 24.04
    • RedHat 8, 9
    • Windows 10, 11
    • Windows Server 2019, 2022, 2025

  • Dependencies
    The dependencies defined in the 'Dependencies' section of the profile itself are required in order to run the workload operations effectively.

    • Internet connection.

    Additional information on components that exist within the 'Dependencies' section of the profile can be found in the following locations:

  • Profile Parameters The following parameters can be optionally supplied on the command line to modify the behaviors of the workload.

    ParameterPurposeDefault Value
    CommandArgumentsOptional. A set of arguments to pass to the MLC toolset. See the MLC Documentation for additional information.

  • Profile Runtimes The following timings represent the length of time required to run a single round of profile actions. These timings can be used to determine minimum required runtimes for the Virtual Client in order to get results. These are estimates based on the number of system cores.

    • (4-cores/vCPUs) = 5 minutes
    • (16-cores/vCPUs) = 20 minutes

  • Usage Examples The following section provides a few basic examples of how to use the workload profile.

    # Execute the workload profile
    VirtualClient.exe --profile=PERF-MEM-LATENCY.json --system=Demo --timeout=1440

    # Override the default MLC command line used
    VirtualClient.exe --profile=PERF-MEM-LATENCY.json --system=Demo --timeout=01.00:00:00 --parameters="CommandLineArguments=--peak_injection_bandwidth"
