profiler tic toc in parallel code

[ArturSalamatin]

Can I use tic and toc methods of amgcl::profiler<> prof in a parallel_for loop?
Will it give correct values, or it will cause race conditions?

Particularly, I am interested in ppl or tbb libraries.

Minimal example is something like this:

#include <ppl.h>
concurrency::parallel_for(size_t(0), (size_t)200, [&](size_t sw_face)
	{
		prof.tic("Name");
		calc_func(nt, sw_face); // abstract
		prof.toc("Name");
	}
	, concurrency::auto_partitioner{});

In fact, tic/toc are to be called inside calc_func for various internal blocks.

No, tic/toc are not thread-safe
