Threads being NUMA aware

Threads being NUMA aware

[Nick Krause]

I am wondering if the project for threads being NUMA aware is still
value as after reading it.
It seems to be obsolete due to it being directly supported in work
queues  by another kernel
layer.
Regards Nick

Please get yourself a NUMA system and test this out.

Russell,
Unfortunately I don't have money for an extra machine as of now as I
am a student
so if x86 is NUMA I can test otherwise I can't.

If you can't get an extra machine then you probably can't contribute to 
developing filesystems, and your ability to do any sort of kernel development 
will be greatly limited.  It's probably best that you choose another area of 
software development until you get more hardware (and skill).

If you had even read the NUMA Wikipedia page then you would already know the 
answer to this implied question.

But really programming computers isn't something that you are good at.  It's 
not something that you will become good at if you attempt tasks that are way 
above your skill level.  I think that the best strategy for you is to find a 
mailing list for Linux beginners, when your skills get to the level that you 
answer more questions than you ask (and people appreciate your answers) then 
you can move on to easy programming tasks.  Once you master the easy 
programming tasks you can move on to more difficult tasks.

I suggest that you develop a realistic plan.  Plan to start kernel programming 
in 2024 and have a series of goals on that path over the next 10 years.  Make 
your 2015 goal be answering lots of questions on a Linux beginners mailing 
list, that's a goal you can achieve in a year.

After reading the article seems it does and just because I don't have
an extra machine doesn't seem to be an issue so
far.
