Re^2: (OT) Programming languages for multicore computers

How often do you think it can be expected that your program will have the whole of the computer to (ab)use? How often do you think the computer doesn't have several other tasks to run?

Programs should not bother about limiting their CPUs/CPU time usage. Actually it is quite the opposite, they should use as many (concurrent) CPU resources as possible in order to finish sooner.

It is the operative system who has the responsibility to ensure that some program does not degrade the performance of any other application running concurrently by just creating too many threads or any other mean.

I'm not talking about limiting themselves artificially. I'm talking about bending backwards to escape the single core limitation. I do believe that most often it's not needed. That most often there's plenty other processes to use the other cores. And that if all those processes attempt to use several cores, they will all finish later than if they did not bother.
