I can think of several advantages that using blocking or signals to
reduce the cpu load would have:
- Reduced energy consumption
- Running additional background programs could be done far more efficiently
- It would be much simpler to examine the load balance.
It may depend on the type of
I noticed that the cpu usage of an mpi program is always at 100 percent,
even if the tasks are doing nothing but wait for new data to arrive. Is
there an option to change this behavior, so that the tasks sleep until
new data arrive?
Why is this the default behavior, anyway? Is it really so costly
