Maximum Number Of Tasks?

[FritzVonBraun <sf@saf.com>]

I was wondering about the maximum number of tasks in Ada but I couldnt 
find any info. The question is, is a task in Ada technically similar to 
a thread in Windows under the hood? Threads are restricted by the stack 
size that each thread has reserved, so in practice the maximum number of 
threads is about 2000.

The reason I'm asking is that I wonder if Ada provides a more 
comfortable solution to the thread pool problem. In C++ for example I 
create a number of threads roughly equal to the number of processor 
cores and then have a number of Jobs that are distributed over the 
threads and which implement a time sharing system by returning control 
to the thread which then assigns time to another Job.

Would I have to do the same in Ada or are tasks meant to be "micro 
objects' of which many can be created and the Ada runtime does 
effectively what my threadpool system does in C++

Thanks for any info
