Can Ultimate Edition change our world

Postby John Spera » Tue Dec 09, 2014 3:20 pm


I have been using Ultimate Edition for a number of years now. I am intuitively drawn to it. However as a software developer for many decades, I would like to encourage the following suggestions.

The video and sound capturing world needs a linux os that remains in a dedicated run state so that frames are not lost. The Mac OS was evolved from a linux model and it is functionally able to accomplish this feat. The os kernal needs a fearure that looks for a dedicated flag set when it looks at the process it wants to swap. When set that process would never be suspended.

For desktop operations that are invoked for input stream capturing, we need the application to be able to set this flag to on. The ability to access process control information needs to be implimented.

Many desktops have 4-8 cores with 8-16 GBs of memory. Will there ever be a need to suspend a dedicated process?

I do have similar linux os suggestions to make. What I do not know where to present them.

Thanks for any assistance with this matter.

Hey John excellent questions and after running through old posts, I'm surprised not to see a response. <BREW> I can't speak for video or sound capturing, but the Linux kernel has many features. And when it comes to memory and process management there are many tweaks and setting that will cover your concerns. ex. Dynamic Memory Allocation, Overcommitting, VmSize, Resident Size, Demand Paging, and you can add the Linux Scheduler to the list too:

And if and depending on what you are running on your Linux OS - 8-16 GB RAM, would determine whether or not you would want to do process management. A server on the other catch my drift. 8-)
