ADSP: Algorithms + Data Structures = Programs Episode 258: π³π΄ An Algorithm Taxonomy (Serial, Parallel, Cooperative)
Oct 31, 2025
Live from Norway, two hosts dive into the fascinating world of algorithm taxonomy. They explore the distinction between serial, parallel, and cooperative algorithms, highlighting how parallel algorithms can appear sequential. Discover the importance of cooperative algorithms, where multiple threads collaborate, and learn why thinking at this level is crucial. The discussion also touches on the efficiency of high-level code and its potential to lead to exciting machine learning developments. Tune in for insights that bridge algorithms and practical programming!

Episode notes
Three-Level Algorithm Taxonomy
- Algorithms fall into three conceptual levels: serial, parallel, and cooperative.
- Each level changes who initiates work and how execution resources are used.
Parallel Algorithms Look Sequential
- Parallel algorithms present a seemingly sequential API while executing work on acquired parallel resources.
- The caller initiates the operation, parallel threads run the work, then results return to the caller.
Cooperative Algorithms Require Participation
- Cooperative algorithms require multiple threads or processes to call and participate together in the primitive.
- They don't acquire resources; the callers donate their execution resources to the collective operation.
