Concurrency Goals
Concurrency behavior in libcortlet-upgradesched is focused on reducing unnecessary coordination overhead while maintaining stable execution under heavy workloads.
Execution Stability
The project is designed to keep task execution consistent during high levels of concurrent activity.
The repository references goals involving:
- reduced thread thrashing
- reduced synchronization overhead
- lower cache invalidation pressure
- stable task coordination under stress workloads
Reduced Coordination Overhead
The project uses lightweight coordination strategies intended to avoid unnecessary blocking and excessive synchronization work between execution paths.
This helps reduce overhead during large task workloads.
High Task Workloads
The repository references stress-oriented testing involving workloads exceeding 50k tasks.
Validation focuses on maintaining stable execution behavior during sustained concurrent activity.
Failure Prevention
The repository references:
- deadlock prevention
- dropped task prevention
- segmentation fault prevention
as part of its concurrency validation process.
Atomic Coordination
The project references explicit memory coordination strategies using:
- acquire ordering
- release ordering
- relaxed ordering
The repository also references avoiding unnecessary reliance on stronger synchronization barriers where lighter coordination methods are sufficient.
Memory Consistency
The project includes cache-aware alignment strategies intended to reduce false sharing and unnecessary cache pressure during concurrent execution.
This helps maintain more consistent scheduling behavior during heavy workloads.
