v0.2.0

New Benchmarks

• Added Video Transcoding Benchmark

Bug Fixes

DjangoBench:

• Fixed patching logic to make sure patches were properly applied when installing on Ubuntu.
• Fixed the bug that Ctrl+C might not end the benchmark.
• Made sure the cleanup command will succeed regardless of the status of kill.

FeedSim:

• Solved unstable multi-instance runs on large core count CPUs and prevented fall-back to
  fixed-QPS runs, thus saving benchmark execution time.
• Fixed potential un-synchronized final 5-min benchmarking phase among mutliple instances.

In Perf monitoring hook:

• Handled topdown errors to prevent blocking results reporting.

TaoBench:

• Ensured TaoBench client would be linked with the openssl 1.1 that came with tao_bench package
  and not the openssl in the system.

Documentation

• Updated READMEs

Feature Improvements

DjangoBench

• Added Standalone mode to enable running DjangoBench on single node
• Added a parameter bind_ip to DjangoBench's db role so that we will be able to
  bind Cassandra DB to a custom IP address using Benchpress CLI command.
• Raised siege concurrency upper limit to 1024 to make sure it will scale up.
• Try infer a JAVA_HOME before starting Cassandra to reduce the chance of Cassandra not
  being able to find JVM

TaoBench

• Added Standalone mode to enable running TaoBench on single machine
• Introduced bind_cpu and bind_mem parameters in TaoBench to let user choose whether to bind NUMA nodes

Perf Monitoring hook

• Also monitor CPU frequency reported by cpuinfo_cur_freq in addition to scaling_cur_freq.
• Monitor power consumption if the system supports power reporting through hwmon.
• Use ARM's topdown-tool to monitor non-NVIDIA ARM CPU's micro-arch and topdown telemetries

v0.1.0
