Multicore OS

Considerations

 The design challenge for a

many-core multicore system is
to efficiently harness the hardware parallelism within

multicore processing power each core processor, known as

and intelligently manage the instruction level parallelism
substantial on-chip resources

efficiently potential for multiprogramming

and multithreaded execution
 Potential for parallelism exists within each processor

at three levels:

potential for a single application
to execute in concurrent
processes or threads across
multiple cores
