tbb::task_scheduler_init class (newbie)

[yesilgulalp]

Hi,

In the past, there was a class named "task_scheduler_init" in the "tbb" library, but I think that class does not exist anymore. For example, instead of the "tbb :: task_scheduler_init :: default_num_threads ()" function, there could be an approach like this link -> https://github.com/oneapi-src/oneTBB/issues/248
My question is how can I determine how many threads to use for execution. Specifically "tbb :: task_scheduler_init init {number};" What can I use instead?

Hi,

Thanks for reaching out to us.

As this issue is more related to TBB, we are moving this issue to the oneAPI TBB forum.

Warm Regards,

Abhishek

You will need to use task_arena and control the concurrency to achieve this effect. When you create a task_arena, you can specify the maximum concurrency, which will set how many threads are used. Please see https://software.intel.com/content/www/us/en/develop/documentation/tbb-documentation/top/intel-threading-building-blocks-developer-reference/task-scheduler/taskarena-class.html for details.
