knowledge of threads working under the hood in the os layer

[kushal bhattacharya]

hi,
I want to know how threads actually work under the hood in the os layer and how it allocates data and other memory related stuffs . Can any of you please give me some references or any book from where i can have a start?
Thanks,
Kushal

Wikipedia is a good place to start:

In my student days I learned about threading, except we didn't call it
treading back then, by implementing time-slice threading on a
single-board computer. Our task was to make a home control system that
could manage the lights and heating pretty much automatically. As I
recall the single board computer used a Z80 processor and we developed
the software using HP64000 workstations, in Pascal and assembly.

I think you can learn a lot by doing roughly the same, except with much
more modern hardware and software. There are two main routes:

* Use a simulation of an old computer. I think a DOSBox comes pretty
close to reality. You can run old PC programs in a DOSBox.

* Use an Arduino or similar. I do not have personal experience with it
but I know it's pretty cheap and does support C++. What I don't know is
if you can take full charge of the beast to e.g. implement threading.


Cheers & hth.,

ok i will try :) by dosbox do u mean virtualvm box ?

I don't know what you already know, but if you don't already know
about processes, you should probably start there. Perhaps with Unix
processes -- there's a lot more material out there on them than on
threads.
