I use pthreads_attr_getthreadsizes() to get default stack size of one thread, 8MB on my machine.
But when I create 8 threads and allocate a very large stack size to them, say hundreds of MB, the program crash.
So, I guess, shall
("Number of threads" * "stack size per thread") < a constant value (e.g. virtual memory size)
?
The short answer is “Yes”.
The longer answer is that all of your threads share one virtual address space, and userspace-usable part of this space must be therefore be large enough to contain all thread stacks (as well as the code, static data, heap, libraries and any miscellaneous mappings).
Multi-hundred-megabyte stacks are a good indication that You’re Doing It Wrong, as they say in the classics.
