Advanced Topic 40 of 51 Concurrency & Parallelism

Load Balancing in Parallel Programs

Distributing work evenly to avoid idle workers.

How it works

Static partitioning assigns equal chunks; dynamic scheduling, work stealing or task queues adapt to uneven work; the slowest worker determines total time.

Where it is used

Irregular workloads like graph algorithms.

Common pitfall

Fine granularity helps balance but adds overhead.

Where it fits in the course

Load Balancing in Parallel Programs is topic 40 of 51 in Concurrency & Parallelism, rated Advanced. It follows Parallel Sorting. The next topic is False Sharing.
