How would you optimize a large-scale simulation written in Julia?

Optimization involves eliminating allocations, ensuring type stability, vectorizing loops, and using parallel execution.

Large simulations in Julia require careful control over memory and computation. Optimization steps include preallocating arrays, ensuring type stability, using @inbounds and @simd, and distributing workloads. GPU acceleration may be used for further scaling. The goal is to make every loop compile into efficient machine code.
