Re: [Algorithms] General purpose task parallel threading approach

[Jarkko L. <al...@gm...>]

Personally, I try to do allocations from the stack when ever possible to
avoid memory fragmentation issues, so 2-4kb stack sounds quite small for my
purposes at least.

 

 

Cheers, Jarkko

So far the experience I (and few others) have says that 2 to 4 kilobytes is
the size which is enough to handle 95% of all cases. You could use same
memory pool for tasks of different sizes (bigger size will result in less
tasks you have in flight), for example - 2 continuous pieces of 4k memory
could be used to create an 8k task.

Also keep in mind that a 2 KB stack is likely to get overflowed REALLY
quickly with any real operations going on.
