One major discussion explored whether processor designers could help address the issue by focusing less on specific applications and single-use benchmarks and more on the operating system and need for hardware to efficiently support many different processes on the machine at the same time. &#8220;There is a growing sense among those who do research into system software that computer architects&mdash;those who design processors and other system components&mdash;need to change their focus,&#8221; reports Timothy Roscoe of ETH Zurich. &#8220;This is partly because many commercially important workloads are now OS-intensive, and some current processor designs incur a high overhead when switching to kernel mode, and partly because as chips become more parallel, the need to coordinate multiple tasks and communicate between multiple applications on cores becomes a key performance bottleneck.&#8221;<\/span><\/span><\/span><\/span><\/li>\n<\/ul>\n<p><i><span style=\"font-family: verdana,geneva;\"><span style=\"font-size: medium;\"><span style=\"font-family: verdana,geneva;\">&mdash;Tim Harris, Senior Researcher, System and Networking Group at Microsoft Research Cambridge<\/span><\/span><\/span><\/i><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The latest innovations in multicore technology are meaningless if the software you run is not written to take advantage of the advanced hardware design.
