I need make my application execute 5 operations in the same time, for that i make the class Operation and extends to Thread, make method do and its work fine buts when i start the threads they don’t run all in the same time. To run i make t1 = Operation.new t2 = Operation.new t3 = Operation.new t4 = Operation.new t5 = Operation.new and t1.join t2.join … I’m doing something wrong ? Why the threads don’t run all the same time? ---

There might be good reasons to do that. I often subclass Thread to give each thread an API for status and interchange, other than just shared variables. That way you can include the required synchronization inside the API. That said, does the OP know that Ruby’s “green threads” will only ever schedule one thread at a time? Even on a multi-core/multi-CPU box? If each thread completes within its timeslice, it will appear that they’re running sequentially. Clifford H…
