$ dpcpp test39.dp.cpp 

$./a.out 
TBB Warning: The number of workers is currently limited to 23. The request for 31 workers is ignored. Further requests for more workers will be silently ignored until the limit changes.

Max error: 0

Hi,


Thanks for reaching out to us.

We are not getting this type of warning as you are getting.

As your warnings are more related to TBB we are moving this issue to the TBB forum, so that the TBB developer can help you with that.


Warm Regards,

Abhishek

DPCPP/SYCL on CPU executes TBB underneath – and it looks like the machine has 24 cores (23 + master thread).  Somehow, DPCPP requested more cores. I cannot reproduce this issue internally.
