In this repository, you will find the assignments for the "Introduction to Concurrent Programming" series at Hydra'22. All assignments are in Kotlin and leverage the kotlinx.atomicfu library that simplifies using the concurrent primitives, such as Compare-and-Set and Fetch-and-Add. Please see the example of the atomic counter implementation in src/counter to get the intuition on how to use the library.

Please complete the Treiber stack and Michael-Scott queue algorithms in the src/stack and src/msqueue folders. To check the implementations for correctness, run ./gradlew test --tests "stack.*" and ./gradlew test --tests "msqueue.*", correspondingly.

Please complete the Fetch-and-Add-based queue implementation in src/faaqueue and implement a concurrent queue that leverages the flat-combining technique in src/fcqueue. To run the tests, use ./gradlew test --tests "faaqueue.*" and ./gradlew test --tests "fcqueue.*".

Please make the classic Dijkstra algorithm concurrent with a Multi-Queue or Stealing Multi-Queue under the hood in the src/dijkstra folder. To run the tests, use ./gradlew test --tests "dijkstra.*".
