December 28, 201015 yr There are a number of reasons to support more than 4 cores (AMD Phenom II X6, for example). Since so many tend to use HandBrake, it makes sense that we would want support more than the current 4 cores in the kernel.
December 28, 201015 yr I'm already playing with a Slackware 13.1 box with the AMD Phenom II X6 1090T and 6 GB DDR3-1600 RAM ... it was supposed to be my new main system. I have unRaid running on it as a test server for 4.6 final (hopefully soon 5.03beta?) ... and sent Tom an email regarding other issues but mentioned that only four processors got configured. Now I'm trying to get Slackware 13.1 installed with multilib 64/32 and VMWare 2.02 ... I got past the missing autoconf and utsrelease files and then I got stuck at the vmmon not compiling ... then reinstalled and am trying from the start again. Then to integrate the right unRaid to the right kernel ... and then to install Windows XP in a VM to run all those nasty old windows programs for compressing video.
December 28, 201015 yr and then to install Windows XP in a VM to run all those nasty old windows programs for compressing video. Are you aware you can run handbrake natively on unRAID? No need for the VM if you can handle the command line version. See here: http://lime-technology.com/forum/index.php?topic=7265.msg70593#msg70593 Allowing the use of the max available cores on your CPU would not hurt though. Joe L.
December 28, 201015 yr Yes I was and I could probably do a few scripts around it, I almost always compress the files the same way, I just have to watch the automatic cropping ... Currently I am using MediaShrink a wrapper written by EvilPenguin on the SageTV forums to automate reasonable cropping and selecting the right switches for Handbrake. If I could get the same script to work natively under unRaid then it would be perfect with much less hair pulling (it's written in perl but tailored for windows machines) I was also thinking that if I did succeed in making an unRaid development system (with unRaid running from a full Slackware install) it would be using all the cores ... depending on the resources used it would be really good to have all the cores 'out of the box' if it didn't make unRaid too big ...
January 4, 201115 yr Author To get back to topic, accessing the other cores really has nothing to do with using HandBrake under a VM. I, for example, never use the graphical version of HandBrake because I understand the options. But since I can, in essence, get two additional cores for around $20 on an AMD X6, it seems unfortunate that I wouldn't be able to use them because of the kernel configuration.
January 5, 201115 yr From linux 'menuconfig': CONFIG_NR_CPUS: This allows you to specify the maximum number of CPUs which this kernel will support. The maximum supported value is 512 and the minimum value which makes sense is 2. This is purely to save memory - each supported CPU adds approximately eight kilobytes to the kernel image. Currently set to 4, what's the correct number I should set this to, maybe 16?

Modern 4 core CPU's from Intel also do hyperthreading so they present themselves as 8 total cores. 8 or 16 should be good but 16 should make it so you will not have to change it for quite a while.

Ok, "16 ought to be enough for anybody"
January 5, 201115 yr Except University of Glasgow researchers More realistically though, Sandy Bridge is slated to release with dual and quads and Intel plans to release 6 and 8 core variants in the future. 16 should be good enough for awhile, but probably not as long as the 4 CPU limit lasted. And I want my 256k of memory back!
January 28, 201115 yr Author This change is greatly appreciated. In which version would we see the change? I ask only because I am buying next week and want to make sure I buy the most logical processor.
