I'm using parallel_sort and regretfully my comparator needs to use a object that is not thread safe. I can make copies of this object for each thread and then the comparator would just need to use the right copy for the thread it is on, kind of like a thread_local but not global.
I'm looking for some tips on how to achieve this with TBB. I know task_scheduler_observer and enumerable_thread_specific are both options for implementing thread_locals but I'm not sure which is better in my case.
Thanks in advance!
