If you are using Spring’s Java-configuration, your config class needs to implements AsyncConfigurer: @Configuration @EnableAsync public class AppConfig implements AsyncConfigurer { […] @Override public Executor getAsyncExecutor() { ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor(); executor.setCorePoolSize(2); executor.setMaxPoolSize(5); executor.setQueueCapacity(50); executor.setThreadNamePrefix(“MyExecutor-“); executor.initialize(); return executor; } } See @EnableAsync documentation for more details : http://docs.spring.io/spring/docs/3.1.x/javadoc-api/org/springframework/scheduling/annotation/EnableAsync.html

Simultaneous mutable access to arbitrary indices of a large vector that are guaranteed to be disjoint

When the compiler can’t enforce that mutable references to a slice elements aren’t exclusive, Cell is pretty nice. You can transform a &mut [T] into a &Cell<[T]> using Cell::from_mut, and then a &Cell<[T]> into a &[Cell<T>] using Cell::as_slice_of_cells. All of this is zero-cost: It’s just there to guide the type-system. A &[Cell<T>] is like a … Read more
