## Designing an ultra low-overhead multithreading runtime for Nim Mamy Ratsimbazafy mamy@numforge.co ## Hello! ## I am Mamy Ratsimbazafy During the day blockchain/Ethereum 2 developer (in Nim) During multithreading: definitions and use-cases Parallel APIs Sources of overhead and runtime design Minimum viable runtime plan in a weekend ## Understanding the design space Concurrency vs parallelism, hardware threads The same distinctions can be done at a multithreaded language or multithreading runtime level. ## The problem ## How to schedule M tasks on N hardware threads? ## Latency vs Throughput
