Portfolio --> Scenarios --> Trace state failed with Bitbrains small

[SauliusITnt]

Hello OpenDC team,

I'm currently working on a data center simulation project using OpenDC 3.0 (local version on Windows). When running a scenario with the “Bitbrains Small” workload trace, the simulation fails with a java.nio.file.NoSuchFileException for the file:

traces\bitbrains-small\trace.parquet

The console output also includes this message:

Simulation job [ID] failed: java.nio.file.NoSuchFileException: traces\bitbrains-small\trace.parquet

I have checked the installation and the traces/bitbrains-small/trace.parquet file is missing. It is not included in the project’s GitHub repository, nor is there documentation on where to obtain it.

Additionally, at startup I see this warning:

WARNING: A terminally deprecated method in sun.misc.Unsafe has been called
WARNING: sun.misc.Unsafe::objectFieldOffset has been called by org.wildfly.common.lock.SpinLock ...
WARNING: sun.misc.Unsafe::objectFieldOffset will be removed in a future release

Could you please advise:

Where can I download the required bitbrains-small/trace.parquet file?

Is there an alternative workload trace I could use for testing purposes?

Should I be concerned about the sun.misc.Unsafe warnings in the current version?

Thanks in advance for your help!
