Micro-benchmarks

Raw data

The black line at revision 11490 marks when we changed the system where the microbenchs are run.

The purle line at revision 12298.5 marks when the default scheduler was switched to use tree-based worker iterators, and the green line at revision 17026.5 marks when this was reverted.

The black line at revision 19182.5 marks when we changed again the system where the microbenchs are run.

The black lines at revisions 19320.5 and 19451.5 mark the period when the kernel was switched to 4.8.11 instead of the usual Debian 4.5.0

Tasks Overhead

This is the time to submit a task, from the main thread:

This is the time to execute an empty tasks:

This is the total time to submit & execute an empty tasks:

Synchronous Tasks Overhead

This is the total time to submit & execute a synchronous task:

Asynchronous Tasks Overhead

This is the total time to submit & execute an asynchronous task without dependencies:

Tasks size Overhead

This shows the speedup of running small tasks sizes on 60 cores of a 64-core machine. The highest curve (in blue) is for 4096µs tasks, the next curve (in green) is for 2048µs tasks, the next curve (in purple) is for 1024µs tasks, etc.
