#2832: possible race condition in LoopControl

 Reporter: Roland Haas
   Status: new
Milestone: 
  Version: 
     Type: bug
 Priority: major
Component: 

Comment (by Erik Schnetter):

We don’t need `new` or `std::vector`. We replace the call to `new` with `posix_memalign`, and the call to `delete` by `free`. Then each thread has one cache line as intended.

Alternatively, there could be one call to `posix_memalign` allocating memory for all threads, and each thread uses pointer arithmetic to find its place.
