Microsoft It seems like Microsoft Research is really busy these days with research operating systems. We had Singularity, a microkernel operating system written in managed code, and late last week we were acquainted with Barrelfish, a "multikernel" system which treats a multicore system as a network of independent cores, using ideas from distributed systems. Now, we have a third contestant, and it's called Helios.

Return of the operating system

Reading this and really the last two weeks of news at OSNews, I am starting to get the feeling that operating systems are coming back into style.

It seems like just a few years ago, whenever an alternative operating system was presented on OSNews, there would always be at least one post about how we already have Linux/BSD/Windows/[insert OS here]. This would always lead into someone saying that there is no longer a need for alternative operating systems.

However with the introduction of multiple core as well as the rise of mainstream multiple processor computers, there has been a large push to really make programs (including OS's) more parallel.

It is great to see that there is interest in locally distributed operating systems. In my (relatively un-researched) opinion, I would say unless fabrication technologies and/or materials dramatically increase speed, the only way to move personal computers forward is to increase parallelism.

This is why I have been enjoying the news so much recently. With not one but THREE open source (depending on who you talk to) projects coming out of Microsoft, as well as an Alpha1 release from Haiku (BeOS arguably being the first "parallel" OS's), it has been a fun time for an operating system geek.
