[Omp] Threadprivate variables and nested parallelism

[Marina Kraeva]

Hello,

I could not find in API 2.5 what will happen if a threadprivate variable 
is referenced within a nested parallel region, other than this:

The values of data in the threadprivate objects of threads other than 
the initial thread are guaranteed to persist between two consecutive 
active parallel regions only if all the following conditions hold:
• Neither parallel region is nested inside another parallel region.


I would think that each thread of the initial team (created for the 
nesting parallel region) will create a new team, and the threadprivate 
copy of this thread will become shared among threads in the new team in 
the nested parallel region (so there will be NT shared variables, where 
NT is the number of threads in the nesting parallel region).

Am I correct assuming this? Can I count on this behavior or it's undefined?

Thank you,
Marina Kraeva.
