2024-10-03Show executed during match target count in match progressBoris Kolpackov1-2/+2
2024-05-09Try to improve deadlock detection accuracy (GH issue 319)Boris Kolpackov1-1/+11
2024-02-26Add ability to request serialization from schedulerBoris Kolpackov1-10/+15
In particular, this can be used to make sure no other recipe is being executed in parallel with the caller.
2022-05-17Handle stack size querying on OpenBSDBoris Kolpackov1-1/+13
2022-02-17Add support for cheaply starting parallel scheduler pre-tuned to serialBoris Kolpackov1-8/+23
2021-05-13Do lazy allocation of shadow task queuesBoris Kolpackov1-7/+5
2021-05-12Deal with helper thread starvation during phase switchingBoris Kolpackov1-7/+139
The implemented solution entails shadowing old phase queues so that helpers don't pick up old phase tasks and boosting the max_threads count so that we can create more helpers if all the existing ones are stuck in the old phase.

2020-08-07Add ability to allocate additional active threads to current threadBoris Kolpackov1-2/+32
2020-08-06Double default task queue sizeBoris Kolpackov1-1/+1
Testing shows quite a lot of "full" conditions on low core count (e.g., 2) CPUs (such as Intel U-series).

2019-08-07Distinguish between internal/external wait deactivation in schedulerBoris Kolpackov1-11/+18
This turns out to be necessary for the deadlock detection to work properly.
