Deprecated features in OneAPI TBB: runtime_loader, task_scheduler_init, atomic

[Przemysław_O_]

Hello,

I have tried to test some code, which we build with Intel C++ Professional 2020, with OneAPI.

TBB reports errors, some headers does not exists anymore:

#include "tbb\atomic.h"

#include "tbb/runtime_loader.h"
#include "tbb/task_scheduler_init.h"

I suppose, that we can simply replace tbb::atomic with std::atomic.

What about runtime_loader and task_scheduler_init?

Is there any replacement/workaround for those features?

Hi Goutham,

thank you for your answer. Those informations were helpful.

Unfortunately, one of the features we use (runtime_loader) is labeled as "No replacement is planned" and we have to find some workaround.
