## 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

## Go runtime related problems in TiDB production environment ## About me Arthur Mao(毛康力), Senior Engineer@PingCAP • TiDB core developer (top3 contributor) • GitBook about golang internals (@tiancaiamao) ready => goroutine wake up == 4.3ms ☐ Sometime even 10ms+ latency here! ☐ The time spend on runtime schedule is not negligible - When CPU is overload, which goroutine should be given priority? ## client lib ## Conclusion - Under heavy workload, goroutines get longer to be scheduled - The runtime scheduling does not consider priority • CPU dense workload could affect IO latency ## Part II -

## Nim - the first high performance language with full support for hot codereloading at runtime by Viktor Kirilov ## Me, myself and I • my name is Viktor Kirilov - from Bulgaria • creator of doctest double=""> x; 2 x $$ 6 $$ = 91.4; c2nim tool - generate C/C++ bindings for Nim ## Runtime compilation - WHY • much faster iteration times ■ no need to restart the program - can preserve powerful ■ fine-tuning values • interactive (REPL-like): very useful for exploration and teaching ## Runtime compilation for C/C++: HOW • replacing entire functions: using shared libraries OR hot-patching:
